Question

In my class, I have field int count. I want to create a new variable according to value of count variable, like this: int a = new Integer(count). But when I update count variable: count++, then variable a also gets updated. So how to create non-referencing int variable?

Answer 1

You can’t do this with Java. Your closest bet would be to create an enclosing class with a single int, and refer to that instead:

class MutableInteger {
    public int value;
}

Then, later:

MutableInteger a = new MutableInteger();
a.value = 5;

MutableInteger b = a;
b.value++;

a.value++;

//since a.value is the same primitive as b.value, they are both 7

But: this breaks a bunch of commonly-accepted best practices in Java. You might look for an alternative way to solve whatever your real problem is.
