public class Hexagon extends Shape implements Cloneable, Comparable<Shape>{

    private double sideLength;

    public Hexagon(double sideLength, String color, boolean filled) {
        super(color, filled);
        this.sideLength = sideLength;
    }

    public double getSideLength() {
        return sideLength;
    }

    public void setSideLength(double sideLength) {
        this.sideLength = sideLength;
    }
  
    @Override
    public double getArea() {
        return 1.5 * Math.sqrt(3) * sideLength * sideLength;
    }

    @Override
    public double getPerimeter() {
        return 6 * sideLength;
    }

    @Override
    public int compareTo(Shape shp) {
        double diff = getArea() - shp.getArea();
        if (diff > 0)
            return (int) Math.ceil(diff);
        else
            return (int) Math.floor(diff);
    }

    @Override
    public String toString() {
        String string = super.toString() + " ";
        string = string + "side= " + sideLength + "area= " + getArea() + "perimeter= " + getPerimeter();
        return string;
    }
   
  
}

This is the class that you need. The main method is given below:

    public static void main(String[] args) throws IOException, CloneNotSupportedException {
        Hexagon h1;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Color: ");
        String color = br.readLine();
        System.out.print("Filled");
        String tmp = br.readLine();
        boolean filled = tmp.charAt(0) == 'y' || tmp.charAt(0) == 'Y';
        System.out.print("Side: ");
        double side = Double.parseDouble(br.readLine());
        h1 = new Hexagon(side, color, filled);
        System.out.println("First hexagon");
        System.out.println(h1);
      
        Hexagon h2 = (Hexagon) h1.clone();
        System.out.println("Cloned hexagon");
        System.out.println(h2);
        if (h1.compareTo(h2) == 0)
            System.out.println("Both hexagon are identical");
        else
            System.out.println("Two hexagons are different");
      
      
      
        System.out.println("Modify the cloned hexagon");
        h2.setSideLength(side + 10);
        System.out.println(h2);
        if (h1.compareTo(h2) == 0)
            System.out.println("Both hexagon are identical");
        else
            System.out.println("Two hexagons are different");
    }

Please post 1 question at a time. Class rectange is very same. still am providing you the rectangle class. I belive you can code teh main

class Rectangle extends Shape implements Cloneable, Comparable<Shape> {
    private double length;
    private double width;

    public Rectangle(double length, double width, String color, boolean filled) {
        super(color, filled);
        this.length = length;
        this.width = width;
    }

    public double getLength() {
        return length;
    }

    public void setLength(double length) {
        this.length = length;
    }

    public double getWidth() {
        return width;
    }

    public void setWidth(double width) {
        this.width = width;
    }
  
    @Override
    public double getArea() {
        return length*width;
    }

    @Override
    public double getPerimeter() {
        return 2 * (length + width);
    }

    @Override
    public int compareTo(Shape shp) {
        double diff = getArea() - shp.getArea();
        if (diff > 0)
            return (int) Math.ceil(diff);
        else
            return (int) Math.floor(diff);
    }

    @Override
    public String toString() {
        String string = super.toString() + " ";
        string = string + "length= " + length + "width= " + width + "area= " + getArea() + "perimeter= " + getPerimeter();
        return string;
    }
  
  
}
