I want to have two routines in a class with same name, same signature but wiht different return type (One with void and another with int return type). Java1.1.8 is not allowing this and giving compilation error. Is there any way to solve it.I need these two routines badly or can I have the routine once with such a return tytpe do that it will work for both void and int type.

How would you propose to use this routine? You could create a method that returns an Integer object or null to simulate this behavior, but you probably should explain (then rethink) why you need such a method.

With OO overloading concept, you can not have more than one method of the same signature.
Method return type does not get counted in method signature.
So just by changing the return type , you can not have same method twice in the given class.

I think this question has been overloaded with to many answers having the same signature.

Try to return something like object (java.lang.Object) from your routine(there can be only one such routine) -
Now if you want int - then type cast object to Integer and get the int value.Hope this helps you.

You could include an int in the signature, that way if your method generates an int it will automatically go back to the calling method.
