Edit method return value in a debugger

Question

Given the following Java code, how can I use the IntelliJ or Eclipse debugger to return false from the condition() method?

public boolean condition() {
    return (4 == add());
}

public int add() {
    return 2 + 2;
}

Answer 1

In Eclipse you can use Force Return.

Just place a breakpoint on return (4 == add()); and type false on the Display view-tab. Then make a selection of your false, right click and hit "Force Return".

Answer 2

In IntelliJ (since IDEA 15 EAP) you can use Force return.

Extract from jetbrains' blog

You can force the return from the current method without executing any more instructions from it:

NB :

If the method returns a value, you’ll have to specify it (smart code completion provided).

If the method has try-finally blocks, you’ll be able to choose whether to execute them or not.
