If RuntimeException is thrown, can it be caught as an Exception?

Question

If I have a try block that throws a RuntimException subclass, can a subsequent catch block catches it as an Exception? Specifically:

public class MyAppException extends RuntimeException {
    // ....
}

// In some other part of the code:
try {
    // Executing this results with doSomething() throwing a MyAppException.
    int x = doSomething();
} catch(Exception exc) {
    // Does the thrown MyAppException get caught here?
}

My thinking is yes, because a RuntimeException extends Exception. However I have some production code that is not behaving this way. So obviously, if the answer is no, then that's my answer; otherwise I need to dig down and see why my code is breaking bad. Thanks in advance!

Answer 1

RuntimeException is derived from Exception, so it will get caught.

Having said this, don't do it! Runtime exceptions should be prevented, not caught.

Answer 2

Yes. It will catch RuntimeExceptionbut in case any Exception arise in catch block that you have to catch again.

I would suggest you to make a local deployment and debug the code.
