Handling Errors: An Introduction to Exceptions

IN THIS COURSE

• 1.  Course Overview
  2m 9s
  In this video, you’ll learn more about your instructor and this course. In this course, you’ll learn the concept of Java exceptions from both a theoretical and practical standpoint. You’ll look at what an exception is in the context of Java from a conceptual point of view. You’ll then learn how these are implemented in the language. You get some hands-on programming experience and learn about compile-time errors and how they’re different from exceptions. FREE ACCESS
• 2.  Exceptions in Java
  12m 3s
  In this video, you’ll learn more about exceptions in Java. In Java, an exception is an event that occurs sometimes when the program is running and has the effect of disrupting the regular flow of the program. A program may be coded to run in a specific manner, but when an exception occurs, the normal flow is effectively interrupted and an exception is thrown. Here, you’ll look at different categories of exceptions in Java. FREE ACCESS
• 3.  The Java Exception Stack
  5m 51s
  In this video, you’ll learn more about some of the more specific mechanics around exceptions and how this can help identify the source of the exception itself. You’ll take a look at a somewhat complex scenario where you have a chain of methods, each one calling another. In this scenario, it may not always be clear where exactly an exception has been thrown.

• 4.  Identifying Compile Errors in Java
  8m 14s
  In this video, you’ll learn more about working with exceptions in Java. You’ll learn it’s important to draw the line between compile time errors and exceptions that can be caught by the compiler and which must be explicitly handled. You’ll begin by exploring some compile-time errors and move on to exceptions. In these demos, you’ll use the IntelliJ IDE to write code. FREE ACCESS
• 5.  Defining Unchecked Exceptions in Java
  11m 39s
  In this video, you’ll learn more about exceptions in Java. Exceptions are issues that can occur during a program's execution, that interrupt its normal flow. Some of these exceptions can be identified by the compiler even before you perform a build of the program. However, there are others that will only occur during runtime, and you can only identify them through experience or by executing the program during the development and testing phases. FREE ACCESS
• 6.  Working with Checked Exceptions in Java
  12m 1s
  In this video, you’ll learn more about checked exceptions through a demo. These are exception tags that are detected by the compiler. You won’t be able to build your application without addressing those exceptions first. Onscreen, you’ll see you need to paste in some new code and import the java.io.FileReader class. You’ll then try to read a file that is present on your file system. FREE ACCESS
• 7.  Course Summary
  1m 40s
  In this video, you’ll summarize what you’ve learned in this course. In this class, you’ve learned the concept of Java exceptions from a theoretical and practical standpoint. You looked at what an exception is in the context of Java from a conceptual point of view and learned how these are implemented in the language. You gained hands-on programming experience and covered what compile time errors are and how these are different from exceptions. FREE ACCESS
