Java Exception Handling is a framework for managing runtime errors to maintain application stability. It includes try-catch-finally constructs, classification of exceptions into checked and unchecked, and the use of 'throw' and 'throws' keywords. Best practices involve catching specific exceptions, custom exceptions for unique errors, and thorough error management.

Java Exception Handling is used to manage runtime errors and improve the stability and user experience of Java applications
Try-Catch-Finally Constructs
The try block contains code that may throw an exception, the catch block specifies how to handle the exception, and the finally block is used for cleaning up resources
Checked and Unchecked Exceptions
Exceptions in Java are divided into two categories: checked and unchecked, which must be understood for effective error handling
Custom Exceptions
Developers can create custom exceptions to address specific error conditions in their applications
Adopting best practices, such as catching specific exceptions, providing informative error messages, and regularly reviewing and testing the code, is crucial for creating a reliable error handling strategy
Basic handling involves using try-catch blocks for common exceptions
Multiple Catch Blocks
Multiple catch blocks can be used to handle different types of exceptions
Finally Block
The finally block is used to execute code after the try and catch blocks, regardless of whether an exception was thrown
Throws Keyword
The throws keyword is used to indicate that a method may throw exceptions and specify the types of exceptions that must be handled
Custom exceptions should be well-documented and integrated into the overall error handling framework for specific application error conditions
00
Java try block purpose
Encloses code that might throw an exception, initiating exception handling.
01
Function of catch block in Java
Specifies how to manage exceptions thrown in try block, defines error handling.
02
Role of finally block
Executes code after try/catch, regardless of outcome, often for resource cleanup.
