Is Java's exception handling mechanism an example of the Chain of Responsibility design pattern?

Question

I have been reading about the Chain of Responsibility design pattern which basically allows a decoupling between the sender of a request and receiv

Answer 1

You are right. Exception handling in Java is based on Chain of responsibility pattern In this pattern:

1. Sender will not know which object in the chain will serve its request
2. Each node in the chain may decide to serve the request --> catching an exception and
   wrapping it with an Application specific exception
3. Each node can forward the request --> throwing exception to the immediate caller
4. None of the node can serve the request --> Leaves the job with the caller

Hence, Exception handling is a Chain of responsibility pattern
