Question

Is there a way to detect, from within the finally clause, that an exception is in the process of being thrown?

See the example below:

 try {     // code that may or may not throw an exception } finally {     SomeCleanupFunctionThatThrows();     // if currently executing an exception, exit the program,     // otherwise just let the exception thrown by the function     // above propagate } 

or is ignoring one of the exceptions the only thing you can do?

In C++ it doesn’t even let you ignore one of the exceptions and just calls terminate(). Most other languages use the same rules as java.

Answer 1

Set a flag variable, then check for it in the finally clause, like so:

boolean exceptionThrown = true; try {    mightThrowAnException();    exceptionThrown = false; } finally {    if (exceptionThrown) {       // Whatever you want to do    } }
