Question

(10 points) What are the precise outputs of the following program when they are compiled and run.

class ObjCreator {

public static int a, b;

public static void main(String[] args){

ObjCreator obj1 = new ObjCreator();

ObjCreator obj2 = new ObjCreator();

obj1.a=20;

obj1.b=100;

obj2.a=obj1.a+10;

obj2.b=obj1.b+10;

swap(obj1, obj2);

System.out.println(obj1.a+" "+obj1.b);

System.out.println(obj2.a+" "+obj2.b);

}

public static void swap(ObjCreator obj1, ObjCreator obj2){

ObjCreator temp = obj1; obj1=obj2; obj2=temp;

}

Obj1.a have 20 and Obj1.b have 100

but while assigning to Obj2.a as Obj1.a+10, Obj2.a and Obj1.a both have the same values as 30.

in the same way Obj2.b and Obj1.b have 110.

after swaping also, both have the same values.

Output: 30 110

30 110
