how to construct a square

i have the cordinates of each corner but i dont know what to do with them.  I think that i need to take all those cordinates and put them together but im not really sure how.

any help

Thanks
Ted


      Square s = new Square(30,20,50,10);
      
      System.out.println("\nSquare:");
      System.out.println("The Distance From Top Left To Top Right = " + s.topLeft.getDistance(s.topRight));
      System.out.println("The Distance From Top Left To Bottom Left = " + s.topLeft.getDistance(s.bottomLeft));
      System.out.println("The Distance From Bottom Left To Bottom Right = " + s.bottomLeft.getDistance(s.bottomRight));
      System.out.println("The Distance From Bottom Right To Top Right = " + s.bottomRight.getDistance(s.topRight));      

      System.out.println(s.enclose);

      }
}
