java - what is exception propagation?

Question

What is exception propagation? I tried to Google it, but couldn't find satisfactory results. Preferably explain this in terms of Java.

Answer 1

It's explained, surprisingly, in the Java tutorial page about exceptions.

An exception propagates from method to method, up the call stack, until it's caught. So if a() calls b(), which calls c(), which calls d(), and if d() throws an exception, the exception will propagate from d to c to b to a, unless one of these methods catches the exception.
