Modeling Entities in Java: Getting Started with Classes & Objects
Classes are a core concept in Java's object-oriented programming model. The class is an abstract type and an object is an instance of that type. Object oriented Java programming allows classes to be instantiated and inherit features from the Java.lang.object. You will learn about member variables, fields, functions, and methods. Learn to instantiate objects of built-in Java classes and invoke methods on them.

Modeling Entities in Java: Defining Custom Classes & Objects
Modeling entities in the real world require you to create custom classes to add to the various built-in classes already provided by Java. Creating such custom classes is key to harnessing the power of object-oriented programming (OOP) in Java. This course focuses on defining such custom classes and then creating objects. Make the most of this course by exploring custom classes, the use of constructors, and modifiers such as private and public. You will also learn the idiomatic Java method of working with getter and setter methods as well as conventions in naming, input parameters, and return types from such methods. After completing this course, you'll not only be able to define custom classes to serve as types in your programs but also instantiate and use objects of these custom classes.

Java OOP: Understanding Inheritance & Polymorphism in Java
In this course, you will explore the basics of inheritance and run-time polymorphism in Java, and how these concepts can be used to model Is-A relationships. Begin with an introduction to inheritance, and how to identify its advantages and applications. You will then apply inheritance to model real-world entities. Next, learn the concepts of polymorphism, its advantages and applications. Then move on to recognizing how the methods derived from java.lang.Object work, and also how all built-in Java classes possess the methods derived from java.lang.Object. You will examine how objects of derived classes have independent copies of member variables, even from the derived class. Following an introduction to the Is-A relationship, you will learn how to recognize, in single inheritance, that every object of the derived class is an object of the base class, but not every object of the base class is an object of the derived class. Explore how to upcast and downcast, and learn how downcasting can sometimes be dangerous. Finally, learn how one base class can be created with multiple derived classes.

Java OOP: The Role of Constructors in Inheritance
In this course, you will learn the role of constructors and how to use the super keyword in architecting inheritance hierarchies in Java. You will begin by identifying the role of access modifiers and recognizing the basics of superclass constructors. When you add your own constructor, you will see that Java takes away the default no-argument constructor it had provided. You will learn how to apply the two ways of initializing derived classes: implement an explicit no argument constructor in the base class or use the super keyword and have only parameterized constructors in both the base and derived classes. You will recognize that a base class's constructor is invoked when a derived class object is instantiated and identify what happens when there is a base and derived class that have many different constructors. You will be able to initialize member variables: add a member variable into a derived class and ensure it is correctly initialized, even in addition to any invocations of the base class constructor.

Java OOP: Multi-level Inheritance
In this course, learners will focus on creation of multilevel inheritance in Java and how such hierarchies include child and grand-child classes that all inherit from a common ancestor base class. Begin with an introduction to multilevel inheritance, and how you can access multiple derived classes by using a base class in multilevel inheritance. Explore use of the instanceof operator, where you can check that an object is an instance of every class in its inheritance hierarchy. Concerning the Is-A Relationship, you will learn how to apply multilevel inheritance when every object of the derived class is an object of the base class, but not every object of the base class is an object of the derived class. Examine downcasting; see how to upcast multiple levels; learn why downcasting is very dangerous; and perform various upcasting operations. After moving on to multilevel inheritance hierarchies, you will construct two parallel base classes and derived classes for each of those base classes. Finally, explore use of the extends keyword, recognizing situations where multiple inheritance is allowed.

Java OOP: Understanding Overriding & Hiding in Inheritance
In this course, you will learn about method overriding, including the use of the super keyword from contexts other than within constructions, and also examine the behavior of static methods. To start, participants learn how to apply method overriding and recognize the concept of hiding, and use the super keyword inside any method invocation in the derived class. This follows on to the use of advanced forms of overriding, combining method overriding with complex inheritance hierarchies. Study static methods and static binding, recognizing that static methods do not support run-time polymorphism. Examine pitfalls to avoid with static methods by learning to recognize how static methods are bound using compile-time rather than run-time binding. Learn how to correctly override the method .toString, which is inherited from java.lang.Object, and describe how the .equals method and the == operator are related. Explore how to correctly override the .hashCode method and write the code to correctly override the .equals method, inherited from java.lang.Object.

Java OOP: Access Modifiers for Regulating Access
In this course, you will learn about access modifiers that can be used to tag member variables and member functions inside Java classes to regulate how these can be accessed from different contexts. Participants begin by examining the properties of public, private, and protected access modifiers. These properties govern how classes, member functions, and member variables can be accessed within the same class, outside the same class but within the same package, and in entirely different packages. This leads into an examination of cross-package access and how access works from one package into another. You will then learn about the semantics of protected members, and the use of the protected access modifier. Next, explore the cross-package access of protected members, which enables you to use the protected keyword across packages. As the course concludes, you will learn about the semantics of using default access modifiers both inside and outside the same package.

Java OOP: Interfaces & Anonymous Classes
In this course, you will focus on one of the most important concepts in all object-oriented programming for Java, the interface. Learners explore how anonymous inner classes provide lightweight instantiations of interfaces, and how interfaces are pure abstract entities. Begin with an introduction into using interfaces and how all their methods are abstract by default. Examine how the instanceof operator works the same way with interfaces as with classes. This leads on to combining the extends and implements keywords: implementing a derived class that can extend a base class and implement an interface. Then learners learn to set up two inheritance hierarchies and combine these into a set of objects that implement both sets of interfaces. Advanced features of interfaces are also examined. Learn how interfaces can support default method implementations. You will set up a class that implements some of the methods of an interface and declares itself abstract. Finally, you will create and define anonymous inner class objects and access outer class variables from your anonymous inner class.

Mapping Relationships in Java: Modeling Is-a Relationships Using Inheritance
Java is an object-oriented programming language, meaning Java programs and frameworks are built on the pillars of inheritance and runtime polymorphism. Inheritance is used to model is-a relationships between classes; such relationships could include either behavior and state or just behavior alone. Use this course to appreciate how classes can be used to model an entity's state and behavior and inheritance to model is-a relationships between two classes. Create various objects of the universal base class Java.lang.Object and of other built-in and custom classes. Use the instanceof operator and the getClass method. Create an inheritance hierarchy out of custom classes. Then, practice using up-casting and down-casting on your objects to explore the relationship between variable types, object types, and inheritance. By the time you're finished, you'll clearly understand how inheritance is a powerful mechanism for code re-use and modeling is-a relationships in Java.

Mapping Relationships in Java: Overriding Methods and Using Access Modifiers
Method overriding is a way in which a derived class can redefine - and override - the implementation of a method already defined in a base class. By overriding only those methods you absolutely need to and relying on the base class implementations for all others, you get a lot done with relatively little new code. Use this course to learn how to carry out this technique. Explore the somewhat surprising behavior of static methods and the phenomenon known as hiding. Use the final keyword to mark member variables, member functions, and even entire classes. Use the abstract keyword to indicate a given method is not implemented. Study the semantics of the access modifiers public, private, protected, and package-private. When you're done, you'll recognize how overriding differs from hiding, the semantics of access modifiers, and how abstract classes are used.

Classes in Java: Implementing Functional Interfaces Using Lambdas
Lambda expressions allow you to define classes that implement single-method interfaces in a very concise and compact manner. This makes code that uses lambda functions easier to read and understand and much more maintainable. Lambda expressions can be made even more compact and readable by the use of method references. In this course, you will learn to create and use lambda expressions to implement functional interfaces. You will see that lambda expressions are essentially blocks of code that accept input arguments, perform operations, and return values. Lambda expressions can be used in any place where we use anonymous classes or a named class that implements an interface with just a single abstract method. You will see that lambdas can only be used to implement functional interfaces i.e. interfaces that have exactly one abstract method. Such interfaces are usually annotated using the @FunctionalInterface annotation which allows the compiler to detect if the single abstract method contract has been violated for such interfaces. You will understand and implement the four types or categories of functional interfaces, the Predicate, Function, Consumer, and Supplier interfaces. Finally, you will round this course off by exploring and implement method references which are essentially even more compact representations of lambda expressions. When you are finished with this course you will have the skills and knowledge to construct lambda expressions in the right way and use Predicates, Functions, Suppliers, and Consumers to process and store your objects.

Java SE 13: Understanding Classes & Objects in Java
What makes the programming language Java so useful is that can run on multiple platforms. In this course, you will examine Java and its support for object-oriented programming. This course uses real-world entities to demonstrate how member variables represent the state of those entities, and how member functions represent the behavior of those entities. Participants study the various basic types of variables in Java and distinctions between eight primitive types and strings, which are a type of object. You will learn that all basic building blocks of all operations are these basic types of variables. As a practical exercise, create a project in Java with Java's two basic building blocks, the twin concepts of classes and objects. Next, learn to create classes and instantiate objects of these classes. You will discover that all objects in Java come with certain built-in capabilities, because they all inherit from a common ancestor base class. Finally, participants learn how to use constructors, getter methods, and setter methods to configure and initialize Java objects.

This course explores Exception Handling in Java and provides users with a strong conceptual and theoretical foundation and examines practical code-based scenarios. Begin by examining what exceptions are in Java and how Java's class hierarchy addresses errors, runtime exceptions, and checked exceptions. An exception is an event that disrupts the normal flow when executing a program, and you will learn here how to differentiate between exceptions and errors. Participants will learn to use Java's catch-or-specify requirement on code that throws specific types of exceptions. You will also learn that an exception handler is code which deals with a particular exception, both its type and location, in the program. Next, learn the sequence of method calls or function calls which culminated in the exception being thrown. The course will then explore the common runtime exceptions, and see how input-output (IO)-related code often poses special challenges in exception handling. Finally, you will be shown how exception handling is tied to the try-catch keywords.

Java SE 13: Correctly Using Try-Catch-Finally Blocks
This course covers the bedrock of Exception Handling in Java, the try-catch-finally code structure. Participants will cover the class hierarchies in exception handling; the stream and file processing; and how Java's support for exceptions and streams is built around complex class structures. You will learn how code might result in exceptions that are enclosed within a try block. Because this code structure could result in a signal to Java that normal programming might be disrupted and will cause the code evaluation to be short-circuited, the course explores details of catch blocks, including the use of multiple catch blocks; the use of the pipe operator ( - operator) to chain different exceptions within the same catch block; and how catch blocks must be arranged for related exceptions. The last part of exception handling is the 'finally block.' This keyword (finally) is used to ensure the correct release of resources, such as file handles, no matter what handled or unhandled exceptions might arise within the try block.

Java SE 13: Try-with-resources & Custom Exceptions
In this course, you will learn about the correct use of the throws clause, Java's relatively new try-with-resources construct, and the use of custom exceptions. Explore how to correctly use the throws clause while defining method signatures and implementing exception handling in a chain of methods that sequentially call each other. You will learn to ensure that resources are automatically closed, relying on language support, using the try-with-resources construct; and recognize the precise semantics of this construct in Java. This leads to throwing an object of a built-in exception type to respond to an unexpected situation in a program, and differentiating between the semantics of throwing runtime exceptions versus checked exceptions. The correct way to invoke a method that throws an exception of a checked exception type will be examined, along with how to correctly declare or handle exceptions in a chain of functions, each of which throws different types of exceptions. Finally, participants will explore the use of custom exceptions, defining their own exception classes, and then throwing exceptions that belong to those classes.

In this course, you'll identify how graph nodes can be sorted using the topological sort algorithm, which has many real-life applications, such as course scheduling, as well as modeling tasks and dependencies. Next, you'll explore shortest path algorithms, which are used in mapping applications. You'll move on to identify and implement the shortest path in an unweighted graph. Finally, you'll implement Dijkstra's algorithm to find the shortest path in a weighted graph.

Handling Errors: Handling Exceptions in Java
It is important to handle exceptions proactively in Java to ensure that the flow of a program doesn't break on the occurrence of an exception. Take this course to explore the fundamentals of handling exceptions and different constructs available in Java that allow you to do so. Delve into working with try-catch, finally, and try-with-resource blocks to handle various exceptions within your code. These blocks can be used to catch single, multiple, or categories of exceptions, clean up after your code has run, and handle exceptions related to specific Java objects, respectively. Upon completion of this course, you'll be able to implement exception handling within Java effectively.

Handling Errors: Advanced Topics in Exceptions
While handling exceptions is enough for most programmers, if you are building an app that other developers consume, you should know how to throw exceptions proactively and the various options available in Java in this regard. This is precisely the focus of this course. Learn about throwing an exception based on your conditions in a Java program and how nested function calls influence exception throwing and handling. You'll get a chance to explicitly throw an exception using the throw keyword, add complexity to your code by throwing different exceptions based on different conditions, and build a customized Exception class to define an exception that is not covered by Java's library. Having finished this course, you'll have the knowledge to throw exceptions and run your program without breaking its flow.

Spring: Exploring Advices in Aspect-oriented Programming
Aspect-oriented programming (AOP) allows significant, global functionality to be added to your application using a modular and non-intrusive method. The action taken before or after method execution is determined by a piece of code called the "advice." Use this course to practice working with different types of advices, starting with the before advice and after advice. Then, work with around advices, which run checks to determine whether a core operation should run at all and what goes on before and after its execution. Move on to use the after-throwing advice to set an action after an error has been thrown and the after-returning advice to determine the steps after a successful run of a method. Upon completing the course, you'll be able to attach different types of advices to aspects in an application.

Advanced Features in Java: Using Built-in Annotations
In this course, you'll learn how annotations are defined and used in Java. You'll explore three popular built-in annotations, the @Override, @Deprecated, and @SuppressWarnings built-in annotations. Next, you'll examine how the @Override annotation is a valuable aid in detecting and fixing typos in the names of overridden methods, and crucially, helps to detect such issues at compile-time rather than at run-time. Then you'll explore the @Deprecated annotation and see how if you mark a class, method, or variable with the @Deprecated annotation, Java will issue an appropriate warning when you reference that element. You'll also learn about the @SuppressWarnings annotation, which does exactly what its name suggests, and for that reason ought to be used only with extreme caution, if at all. The @SuppressWarnings annotation allows the selective suppression of different types of warnings. You can also entirely eliminate all compiler warnings using @SuppressWarnings annotation with the all input argument, but this is quite dangerous and is an especially egregious programming practice.

Advanced Features in Java: Using Custom Annotations
In this course, you'll learn about two advanced built-in annotations, @SafeVarargs and @FunctionalInterface, before moving on to defining and using your own custom annotations. You'll begin with @SafeVarargs and see that it is purely indicative and does not imply any added compiler checks, so it is important to not be lulled into a false sense of security about methods that have been decorated with this annotation. Next, you'll move to another built-in annotation, @FunctionalInterface. This is used to decorate interfaces that contain exactly one abstract method. Finally, you'll learn how to define and use custom annotations. This will involve a detailed study of target and retention policies. The retention policy determines whether the annotation will be preserved only in source code, into compiled bytecode, or all the way to runtime. Finally, you'll see how the target policy governs what code elements - fields, methods, constructors, type parameters, and classes - can be decorated with an annotation.

Advanced Features in Java: Using Generic Type Parameters
In this course, you'll learn how type parameters can be used to combine type safety and code re-use. You'll see how type parameters can be specified for either for classes or for individual methods of classes. You'll learn that while instantiating objects of those classes, or while invoking those methods, you can pencil in type arguments in place of those type parameters. You'll cover defining type parameters, using classes and methods with type parameters, as well as conventions and rules that apply to such parameters. You'll then explore the raw type that lies beneath any class or method with a type parameter. Java creates just one single copy of such code, and pencils in a type parameter of java.lang.Object. Java also adds various type checks to ensure that the code is used correctly - this is known as type erasure, and forms the basis of the great performance of Java generics. Finally, you'll move on to the use of constraints on type parameters and see how these are achieved using Bounded Type Parameters. Using bounds, it is possible to exercise fine-grained control over the ensure that the type argument - for instance to specify that it must be a numeric type.

Advanced Features in Java: Wildcards and Type Capture
In this course, you'll explore how wildcards and type capture work, as well as how type erasure manifests itself in compiled bytecode. You'll start by examining how the wildcard operator, represented in syntax by the ? character, can be used in situations where you don't know up-front what type argument to specify for a particular type parameter. Next, you'll learn the three types of wildcard type parameters. Unbounded wildcards, where you know nothing at all about the type; upper bounded wildcards, which define type parameters that must inherit from a specific base class or interface; and finally lower bounded wildcards, which can be used to specify constraints in the other direction - namely that the type must be a super-class of a specified type. Next, you'll see that capture errors occur when Java is unable to infer the correct type to pencil in as the type argument for a given type parameter. Finally, you'll examine bytecode to see that whenever you create a class or method with a type parameter, Java creates just one single copy of such code, and pencils in a type parameter of java.lang.Object. It also adds various type checks to ensure that the code is used correctly. This is known as type erasure and forms the basis of the great performance of Java generics.
