Passing by reference in Java?

Question

In C++, if you need to have 2 objects modified, you can pass by reference. How do you accomplish this in java? Assume the 2 objects are primitive types such as int.

Answer 1

You can't. Java doesn't support passing references to variables. Everything is passed by value.

Of course, when a reference to an object is passed by value, it'll point to the same object, but this is not calling by reference.
