How do you handle exceptions in Java?


Java exception handling is important in creating robust, reliable, and error-resistant code. Java exceptions interrupt the normal flow of instructions in a program. They usually occur when an error occurs during program execution. Java has a sophisticated way to handle these exceptions. This allows developers to manage errors gracefully while maintaining the stability of their applications. This guide covers the key concepts, types, and strategies for handling exceptions effectively in Java. Java Classes in Pune



Understanding Java Exceptions


An exception is a situation that arises during the execution of an application, disrupting its normal flow. Java classifies exceptions into two types: checked and unchecked. Understanding these types of exceptions is essential for implementing effective strategies to handle them.



Checked exceptions: These are exceptions that must either be caught or declared within the method in which they may occur. These exceptions extend but exclude runtimeException. The compiler checks for checked exceptions at compile time, requiring handlers to deal with these exceptions.



Unchecked Errors These include runtime errors and exceptions. They extend Java. lang.RuntimeException and java. lang.Error respectively. Unchecked errors are not checked during compilation, so the compiler doesn't require them to be declared or caught. Runtime exceptions can be used to signal programming errors such as logic mistakes or improper usage of an API. Java Classes in Pune | With 100% Placement (2024)
