Course: Handling Errors

Developers need to be aware of the concept of exceptions in the context of Java and how they are implemented in the language so that they can handle it efficiently. Use this course to familiarize yourself with Java exceptions from both a theoretical and practical standpoint.

Delve into the two major categories of Java exceptions - checked exceptions that can be identified at the compile stage and unchecked exceptions which occur while the program is running. Next, you'll be able to try your hand at some hands-on programming and discover how to work with compile-time errors and distinguish them from exceptions.

After finishing this course, you'll be in a position to recognize the purpose and categories of Java exceptions and how to tackle them.

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.

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.
