Rethrow exception in java

Question

I have a very simple question about re-throwing exception in Java.

Here is the code snippet:

public static void main(String[] args) throws FileNotFou         


        

Answer 1

In the example given, re-throwing the Exception serves no purpose.

Doing this can be useful if the method that catches and then re-throws the exception needs to take some additional action upon seeing the Exception, and also desires that the Exception is propagated to the caller, so that the caller can see the Exception and also take some action.
