# More about Objects and Classes

## 18. Testing Two Reference Variables

Answer:No. The == operator tests if two reference variables refer to the same object.


# Testing Two Reference Variables

Here is the program, modified to use the == operator.

The objects are the same as before so the picture is the same as on the previous page.

import java.awt.*;
class EqualsDemo2
{
public static void main ( String arg[] )
{
Point pointA = new Point( 7, 99 );   // first Point
Point pointB = new Point( 7, 99 );   // second Point with equivalent data

if ( pointA == pointB  )
System.out.println( "The two variables refer to the same object" );
else
System.out.println( "The two variables refer to different objects" );

}
}

The == operator looks at the references in the two reference variables to see if those reverences are identical.

Question 18:What is the output of this program?
