What should I enter inside the [? ] to make this java assertion work ?

//The answer must have balanced parentheses
class Point { int x; int y;
  public Point(int x, int y) {this.x = x; this.y = y;}
  [???]
}
public class Exercise{

  public static void main(String [] arg){
    Point p1 = new Point(1,2);
    Point p2 = new Point(1,2);
    assert p1.equals(p2);
  }
}

What I have tried:

I have tried employing the use of a super keyword but that requires I write a new class that extends class Point.

Is there a way to solve this problem without doing so ?

Solution 1

At a guess from looking at your code, you need to write an equals method. As it stands your call to equals will invoke the base object method that just compares the two references p1 and p2. But I assume what you really want to know is whether the two points are referring to the exact same logical position.
