What is exception chaining in Java?

Exception chaining in Java is a technique that allows you to link one exception to another. This is useful when an exception occurs while handling another exception, providing a way to preserve information about the original exception. It enhances debugging and error tracking by maintaining the context of the problem.

When you throw a new exception, you can include the original exception as a parameter in the constructor of the new exception. This allows you to propagate the cause of the exception, making it easier to identify and address issues later on.

Here’s an example of exception chaining in Java:

public class ExceptionChainingExample { public static void main(String[] args) { try { methodThatThrowsException(); } catch (Exception e) { throw new RuntimeException("Error occurred in main method", e); } } public static void methodThatThrowsException() throws Exception { throw new Exception("Original exception"); } }
