How do I use an equivalent to C++ reference parameters in Java?

Question

Suppose I have this in C++:

void test(int &i, int &j)
{
    ++i;
    ++j;
}

The values are altered inside the function and then use

Answer 1

Well, there are a couple of workarounds. You mentioned one yourself. Another one would be:

public void test(int[] values) {
    ++values[0];
    ++values[1];
}

I would go with the custom object, though. It’s a much cleaner way. Also, try to re-arrange your problem so that a single method doesn’t need to return two values.
