Question

Please write in dr java

Write two classes: One class draws a square, and an exception that occurs when the user puts in an invalid dimension. First download the driver and put it in your project o DO NOT ALTER THE DRIVER! . Write a class file called DimensionException that inherits from Exception . Create the following constructors o Default - calls the parent's constructor and pass a message that it is an invalid dimension o A constructor that takes one string parameters that is passed to the parent's constructor . Write a class file called Square that DOES NOT HAVE amain method . An attribute of this class is o Length - corresponding to the length of each side . Create the following constructors o Default - creates a 1xl square (or a single star) o One that has a integer parameter that corresponds to its length and width . Accessors and Mutators for each variable o MAKE SURE THE MUTATORS CHECK FOR VALID VALUES! o If the dimension is set improperly throw the DimensionException . Create the following Methods o draw - this method will draw a square of asterisks (*) by the given dimensions o getArea - returns the area of the square o getPerimeter - returns the perimeter of the square
Here is the driver:

import java.util.*;
public class SquareDriver {
        public static void main(String[] args)
        {
                Scanner keyboard = new Scanner(System.in);
                String input ="";
                System.out.println("Welcome to the easy square program");
                while(true)
                {
                        System.out.println("Enter the length of the side of a square or enter QUIT to quit");
                        try
                        {
                                input = keyboard.nextLine();
                                if(input.equalsIgnoreCase("quit"))
                                        break;
                                int length = Integer.parseInt(input);
                                Square s = new Square();
                                s.setLength(length);
                                s.draw();
                                System.out.println("The area is "+s.getArea());
                                System.out.println("The perimeter is "+s.getPerimeter());
                        }
                        catch(DimensionException e)
                        {
                                System.out.println(e.getMessage());
                        }
                        catch(Exception e)
                        {
                                System.out.println(e.getMessage());
                        }
                }
        }
}

//Square.java
public class Square {
    private int length;
    public void setLength(int length) {
        this.length = length;
    }

    public void draw() {
        for(int i = 0;i<length;i++){
            for(int j = 0;j<length;j++){
                System.out.print("*");
            }
            System.out.println();
        }
    }

    public int getArea() {
        return length*length;
    }


    public int getPerimeter() {
        return 4*length;
    }
}
