Query with Cloning of an Object

[PavanPL KalyanK]

ShallowCloning : A new Object is created , but its variables refer to the same location and the default Object clone method only returns a shallow copy of an Object .

public class Pavan implements Cloneable 
{
int a  =10;
int b = 20;
public Object clone()throws CloneNotSupportedException
{
	return super.clone();
}
public static void main(String args[])throws CloneNotSupportedException 
{
	Pavan pav1 = new Pavan();
	Pavan pav2 = (Pavan)r.clone();
	pav1.a=20;
	System.out.println(pav2.a);
	
}

}

But this gives me (pav1.a) gives me only the value 10 (even though i chnaged to 20 with pav2.a=20)

why the value of a is not copied .


Any ideas ??

int are primitive types and are not obejcts so they dont live in heap. Clone will just copy the value of int and create a new int. Any changes to primitive types will not be reflected.
