What you'll learn

Java applications crash when invalid data arrives, terminate abruptly when resources become unavailable, and fail silently during critical operations.

In this course, Java SE Foundations: Exception Handling, you'll learn to write resilient code that handles failures gracefully.

First, you'll explore what exceptions are, their hierarchy in Java, and how they propagate through the call stack when unhandled.

Next, you'll discover how to catch and handle exceptions using try-catch blocks, work with multiple exception types, and ensure proper cleanup with finally blocks and try-with-resources.

Then, you'll learn to propagate exceptions appropriately using throw and throws, create custom exception classes for domain-specific errors, and preserve failure context through exception chaining.

Finally, you'll understand how to manage resources automatically to prevent memory leaks, handle suppressed exceptions, and apply best practices when dealing with exceptions.

When you're finished with this course, you'll have the skills and knowledge of Java exception handling needed to build robust, production-ready applications that fail predictably, recover gracefully, and maintain system stability when things go wrong.
