Create a test driver to test the functionality of your Rectangle class created in number 14 above.

Question

What will be an ideal response?

Answer 1

```
public class RectangleTest
{
public static void main(String args[])
{
Rectangle r1 = new Rectangle();
Rectangle r2 = new Rectangle(5,6);
Rectangle r3 = r2;
System.out.println(r1.toString() + "\n" + r2.toString() +
"\n" + r3.toString());
r1.setLength(8);
r1.setWidth(10);
System.out.println("The area of r1 = " + r1.getArea());
System.out.println("The perimeter of r1 = " + r1.getPerimeter());
if(r1.equals(r2))
System.out.println("r1 and r2 are equal!");
else
System.out.println("r1 and r2 are not equal!");
if(r2.equals(r3))
System.out.println("The area of r2 and r3 = " + r2.getArea());
else
System.out.println("r2 and r3 are not equal!");
}
}
