16. The equals() Method

Answer:
The x value and the y value of one point is equal to the x value and the y value of the other point.

The `equals()` Method

The equals() method is defined for class Point:

pointA.equals( pointB )   —— returns true if the two points

                             contain equivalent data

The example program shows this:

import java.awt.*;
class EqualsDemo
{
  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.equals( pointB ) )
      System.out.println( "The two objects contain the same data: " + pointA );
    else
      System.out.println( "The two objects are not equivalent: " + pointA + 
          " differs from" + pointB);     

  }
}
