Program 3, “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
Note: The program should include a main method to test that it does the following.
Instantiate a Square object whose upper-left corner coordinates and length are given as command-line arguments. It should print out the area and perimeter of the square.
Prompt the user for a second square’s upper-left corner coordinates and length, and indicate whether it intersects with the square specified earlier and also whether it contains the square specified earlier.
Provide a pop-up window that displays the two squares.
A sample run would be as follows.
java Square 0.2 0.7 0.3
The area is 0.09
The perimeter is 1.2
Enter the upper-left coordinates and the length of a square: 0.3 0.6 0.4
It intersects the first square.
It does not contain the first square.
Also a window should pop up that displays both the squares.
