Definition
Exception handling in Java is a mechanism to handle runtime errors, allowing the program to continue its normal flow even when unexpected events occur. It uses try-catch blocks to manage exceptions that may arise during program execution.
Summary
Exception handling in Java is a crucial aspect of programming that allows developers to manage errors effectively. By using try-catch blocks, programmers can catch exceptions and handle them gracefully, ensuring that the application continues to run smoothly. This mechanism not only improves the user experience but also helps in debugging and maintaining code quality. Understanding how to create custom exceptions and using the finally block for resource management are essential skills for any Java developer. By following best practices in exception handling, developers can write robust applications that are resilient to errors, making their software more reliable and user-friendly.
Key Takeaways
