Onother question. Is java have call by value and call by

reference for primitive like int?

Like this

Int day = 30;
System.out.println(day);// show 30

Public void change(int T){
T=50;
}

Change (day);
System.out.println(day);// show 50 ?

Is there a way? For example in c++ we use & befor argument

You should use mutable objects. Integer is immutable as well as other primitive wrapper classes.
