int x=1;
int y=x;
System.out.println(y);
x=20;
System.out.println(y);
Obviously the program will print 1 and 1. However, I need to create a reference between x and y so every time i change x, y will be changed as well.

3You need to create an instance of `Integer` instead of primitive int. – Atri Nov 18 '15 at 20:01

In Java world you achieve this little differently than C/C++ . Come back to your question once you understood the object orientation – Abhiram mishra Nov 18 '15 at 20:04

@ashutosh What would that change? – Sotirios Delimanolis Nov 18 '15 at 20:12

@ashutosh `Integer` is an immutable class. – M A Nov 18 '15 at 20:13

1@ashutosh `Integer` isn't mutable, so that wouldn't help anything. You need a wrapper class that can have its value changed, like [`AtomicInteger`](http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicInteger.html). – azurefrog Nov 18 '15 at 20:14
