Please add Commenting (commented each line of the code and used proper variable naming conventions which are self explanatory.)on this

Square," will implement a data type Square that represents squares with the x and y coordinates of their upper-left corners and the length.

The API should be as follows.

Square(double x, double y, double length)//constructor

double area() //returns the area of the square

double perimeter() //returns the perimeter of the square

boolean intersects(Square b) //does this square intersect b? Two squares would intersect if they share one or more common points

boolean contains(Square b) //does this square contain b?

void draw() //draw this square on standard drawing

Code:

import java.util.Scanner;

public class Square {

private double x;

private double y;

private double length;

// Getters and Setters for the private members

public double getX() {

return x;

}

public void setX(double x) {

this.x = x;

}

public double getY() {

return y;

}

public void setY(double y) {

this.y = y;

}

public double getLength() {

return length;

}

public void setLength(double length) {

this.length = length;

}

//Constructor

public Square(double x, double y, double length) {

this.x = x;

this.y = y;

this.length = length;

}

//To calculate are of square

public double area() {

return this.length * this.length;

}

//To calculate perimeter of Square

public double perimeter() {

return 4 * length;

}

// To check if two squares intersect

public boolean intersect( Square s)

{

double p1X = this.x;

double p1Y = this.y;

double p2X = this.x + this.length;

double p2Y = this.y - this.length;

// If one rectangle is on left side of other

if (p1X > (s.getX() + s.getLength()) || s.getX() > p2X)

return false;

// If one rectangle is above other
