For instance variables there will be separate copy for each object created in heap (Not like static objects)

/**

 */

/**
 * @author U0123154
 *
 */
public class Inst {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Demo obj1 = new Demo();
Demo obj2 = new Demo();
obj1.i++;
obj2.i--;
obj1.display();
obj2.display();
}

}

public class Demo {

public int i=10;

void display(){

System.out.println("The value of i is  " +i);

}

}

Output:-

The value of i is  11

The value of i is  9
