Object as Reference not working

Code :

---

public class GG{
 
	public static void main(String[] args) {
		Integer i = new Integer(10);
		System.out.println("Before Call:"+i);
		change(i);
		System.out.println("After Call:"+i);
 
	}
 
	public static void change(Integer x){
		x=20;
	}
}

---

Here the output is coming
Before Call:10
After Call:10


I am confused when i am passing an object in a function then why the value is not changed as objects are passed by reference??

Dont know if this has been answered or not, but you are using local variables, and expecting a global change. You have to either make i global, or change within the main method
