How to change variable value passed by argument?

[Allen]

In C++, we can do it like this:

void Square(int& value)
{
value *= value;
}

How can I do it in Java?

I try the following method, but it does not work.

void square(Integer value)
{
value = value * value;
}

Why would you ask this in a C++ group? comp.lang.java

It is a java question. Why ask it in C++ group?

Uh, yeah, exactly. Did you not read what I just wrote?

That was precisely Mark P's point. This is comp.lang.c++ (i.e. a C++
group), and you asked a Java question here. Why would you do that?

Oh. Sorry, I post it in C++ group.

I believe that newsgroup is dead. Google doesn't offer anymore, neither
does NIN.

I would recommend the forums at:
