Java Core Programming Literacy (Beginner Level)

Topics covered

• compare and contrast the usage of parameterized and non-parameterized lists
• create Predicate, Consumer, Function, and Supplier interfaces
• examine and invoke the methods available in the Iterable interface
• identify how the Comparator and Comparable interfaces are used in tree sets
• illustrate type inference with parameterized methods
• illustrate various aspects of nested static classes
• implement a try-with-resource block to close resources after their use
• implement interfaces with generic types using lambdas
• list examples of checked exceptions in Java and contrast these with unchecked exceptions
• perform filter operations with local and anonymous classes
• recall how Java infers data types using wildcard capture
• recall how the Java compiler uses type erasure with generic types
• recognize different type of map implementations
• recognize how anonymous instances are objects
• throw and handle exceptions at various levels when nested function calls are involved
• use generic types as input arguments to methods and return values from methods
• use inner classes to create iterators for data structures
• use multidimensional arrays to store tabular data
• use multiple bounds with type parameters
• use multiple catch blocks to handle different types of exceptions in your code
