Exception handling is a critical aspect of Java programming that enables developers to manage and respond to unexpected situations that can occur during the execution of a program. Java provides a robust mechanism for handling exceptions, ensuring that errors don't lead to program crashes or unpredictable behavior.

Java classes in PuneIn Java, exceptions are categorized into two types: checked exceptions and unchecked exceptions. Checked exceptions are those that are checked at compile-time, ensuring that they are either caught or declared in the method signature using the throws keyword. Unchecked exceptions, on the other hand, are runtime exceptions that typically result from programming errors and don't require explicit handling.
The try-catch block is at the core of exception handling in Java. The try block encloses the code that might generate an exception, while the catch block catches and handles the exception if it occurs. Multiple catch blocks can be chained to handle different types of exceptions.
Additionally, Java offers the finally block, which contains code that is executed regardless of whether an exception occurs or not. This is useful for releasing resources, closing files, or performing cleanup operations.
The throw keyword allows developers to manually throw exceptions when a specific condition is met. This can be useful for creating custom exceptions that are relevant to a particular application's logic.
Java also includes the concept of "exception chaining," where one exception leads to another. This helps maintain a clear trail of the original issue that caused subsequent exceptions.
Overall, proper exception handling in Java contributes to the creation of robust and reliable applications. By gracefully handling exceptions, developers can provide better user experiences and maintain the stability of their software systems.
