Can anyone help me finish my code for cash ? :P

Can anyone help me with this task ?

Implement a subclass Square that extends the Rectangle class. In the constructor, accept the the x- and y- coordinates of the centre and the siude length of the square. call the setLocation and setSize methods of the rectangle class (look these up !!) Also supply a method getArea that returns the area of the square. Write a test class that makes use of the square class.


So far I have this:



public class Square

{
private int length;
Square (int l) {
this.length =l;
}

public void setLength(int l)

{
this.length =l;
}

}

public int getArea() {
return this.length*this.length;


How do i finish it off ?

Theres a drink via Paypal in it for ya !! :)

Think i may have cracked it :)

Code:

---

import java.awt.*;

public class Square extends Rectangle {

        public Square(int x, int y, int length) {
                this.setLocation(x,y);
                this.setSize(length);
        }
       
        public Square() {
                this(0,0,0);
        }
       
        public void setSize(int length) {
                this.setSize(length, length);
        }
       
        public void setLength(int length) {
                this.setSize(length);
        }
       
        public double getArea() {
                return (this.getWidth() * this.getHeight());
        }
       
        public double getLength() {
                return this.getWidth();
        }
}

Code:

---


class SquareTest {
       
        public static void main(String[] args) {
                Square square = new Square(0,0,4);
                System.out.println("Location: " + square.getLocation());
                System.out.println("Length: " + square.getLength());
                System.out.println("Area: " + square.getArea());
        }
}

Now I need cash. :(
