Question

*****Please Implement in Java*******

Instructions:

Rewrite the provided Rectangle class to extend GeometricObject and implement the Comparable interface. Override the equals method of the Object class.

Two Rectangle objects are equal if their areas are the same.

Implement the compareTo to be consistent with equals method.

The compareTo method will return 0, if two rectangle are eqauls

The compareTo method return 1 , if the area of rectangle1 is bigger than the area of rectangle2

The compareTo method return -1, if the area of rectangle2 is bigger than the area of rectangle1

Sample Run:

Note:

The first two numbers are the width and height of the first rectangle followed by the width and height of the second rectangle follow by "==" for equals or ">=<" for compareTo method.

The width and height of a rectangle is a positive value and the default value is 1.

For zero and negative numbers use the default values.

**** Use the following DriverMain class******

class DriverMain{
   public static void main(String args[]){
Scanner input = new Scanner(System.in);
double w1 = input.nextDouble();
double h1 = input.nextDouble();
double w2 = input.nextDouble();
double h2 = input.nextDouble();
String s = input.next();
Rectangle rectangle1 = new Rectangle(w1, h1);
       Rectangle rectangle2 = new Rectangle(w2, h2);
if(s.equals("=="))
System.out.print(rectangle1.equals(rectangle2)) ;
else if(s.equals(">=<"))
System.out.print(rectangle1.compareTo(rectangle2));
else
System.out.print("Invalid");
   }
}
