Answer 1

You can design new class like this:

public class Inte{
       public int x=0;
}

later you can create object of this class :

Inte inte=new Inte();

then you can pass inte as argument where you want to pass an integer variable:

public void function(Inte inte) {
some code
}

so for update the integer value:

inte.x=value;

for getting value:

Variable=inte.x;
