Chapter 8, Problem 22E

Explanation of Solution

Adding the “union” method in the “Rectangle” method:

//definition of "Rectangle" class

public class Rectangle

{

    //declare the required variables

    private int x;

    private int y;

    private int width;

    private int height;

    //definition of constructor

    public Rectangle(int x, int y, int width, int height)

    {

        //check the width or height is less than 0

        if (width < 0 || height < 0)

        {

            //throw an exception message

            throw new IllegalArgumentException();

        }

        //set the values

        this.x = x;

        this.y = y;

        this.width = width;

        this.height = height;

    }

    //definition of "intersection" method

    public Rectangle intersection(Rectangle rect)

    {

/declare the variable and get the maximum value/

        int left = Math.max(x, rect.x);

/declare the variable and get the maximum value/

        int top = Math...
