Answer / lachha g

you can use Instrumentation class.

use long getObjectSize(Object objectToSize) method.
It returns amount of storage consumed by the specified object.
package Test;

import java.lang.instrument.Instrumentation;

public class ObjectSize {
private int x;
private int y;

ObjectSize(int x, int y){
this.x=x;
this.y=y;
}

public static void main(String [] args) {
ObjectSize obj= new ObjectSize(2,4);
System.out.println(Test.getObjectSize(obj));
}
}
class Test {
private static Instrumentation instrumentation;

public static void premain(String args, Instrumentation inst) {
instrumentation = inst;
}

public static long getObjectSize(Object o) {
return instrumentation.getObjectSize(o);
}
}
