The rules: Formulate your answer before you run the code.

The code:

public class TestClass {

/**
*
*/
public TestClass() {
super();
}

public boolean foo() throws ArithmeticException {
try {
int Nan = 1 / 0;
} catch (ArithmeticException e) {
throw e;
} finally {
return true;
}

}

public static void main(String[] args) {
TestClass test = new TestClass();
boolean result = false;
try {
result = test.foo();
} catch (ArithmeticException e) {
e.printStackTrace();
}

System.out.println(result);
}

}
The question:

What gets printed to the console?


a) stack trace, then false
b) stack trace, then true
c) false
d) true

Why?

First off, it's more sensible to have a subject that describes the posting.

This problem is weird. I tried it out on Eclipse with 1.5 and 1.4. The exception is being thrown out of the first method but not out of the second one. It's puzzling.

Doesn't this amount to suppressing the exception by using a finally clause?

Somebody explicate this.

At my end it is showing only true as output.

You did not mention the compiler warning.

[Stuart Ash]: The exception is being thrown out of the first method but not out of the second one. It's puzzling.

I can't tell what you mean by "first method" and "second one". Was the output "true" both times? That's what should happen.

Doesn't this amount to suppressing the exception by using a finally clause?

Yes, this is what normally happens if you either return or throw an exception from within a finally clause - the JVM completely forgets what it was doing (i.e. any original exception that was being thrown is forgotten with no trace) and instead the JVM obeys the newer instruction, returning or throwing a new exception accordingly. Which is almost always a bad thing; hence the compiler warning (which I would prefer were a compiler error, but maybe there are a few rare cases where it's not - I doubt it though).

You have highlighted, once again, the "lost exception" (steal Bruce Eckel's terminology).

I would expect the compile warning. its obligated to respect the finally clause.
