Hello,

Thanks for response.
I will elaborate on the question.
In a java program, I have a main method and another method say A.
I have a exception catcher at the method {Non main} and another excpetion catcher at main.
So i have two exception catchers.
I am wondering if I should throw exception at A , because it will be caught again by main method.
or I should just handle it at exception catcher at A.
