Question

You will write a class called Shoe.java

Shoe.java should have

Three instance variables

• String brand (cannot be blank)
• double size (from 5 to 12)
• int color (a number from 1 to 5 representing one of 5 colors) This code is to control the amount of colors. the colors represented are as follows
  • 1. red
  • 2. green
  • 3. blue
  • 4. black
  • 5. grey

One constructor, one get method per instance variable, one set method per instance variable. You will need a toString method that will return a string with the shoe information.

• Total for this class is 170 points + style 30 points = 200 points
• constructor (25 points)
• Each set method is 20 points
• setBrand
• setSize
• setColor <--- uses an integer to set the color, must be like this: private void setColor(int color)
• Each get Method is 20
• getBrand
• getSize
• getColor <--- even when the color is a number the getColor may return a string or a number. Any way you decide to do it it should run properly with my code and with any other code that may use this class
• The toString method is 25 points
• toString <-- should spell the color. It should not print the color number.

Keep in mind that in order for this to work you will need to create ShoeException.java as well.

ShoeException.java

Total points for this class is 60 for the methods + 20 for style for a total of 80 points

• constructor (20 points)
• setMessage (20 points)
• getMessage (20 points)

The code below can be used to test that your class works well. Copy and paste it into JGrasp in a file to be named ShoeStore.java The code below should run with your code. I have tested it with my own homework code and it works well. the last 40 points will be earned depending on how well your code interacts with the given code below.

import java.util.*;
public class ShoeStore{

   public static void main(String arg[ ]) throws Exception{

      Scanner sc = new Scanner(System.in);
      double size=0;
      String brand = "";
      int color=0;
      boolean exit = false;
      final int ASIZE = 3;
      Shoe sh = null;
    
      try{
         System.out.print("Enter shoe brand: ");
         brand = sc.nextLine( );
         sc = new Scanner(System.in); //resetting the scanner
         System.out.println();
         System.out.print("Enter size from 5 to 12: ");
         size = sc.nextDouble( );
         sc = new Scanner(System.in);
         System.out.println();
         System.out.println("Enter color as a number from 1 to 5: ");
         System.out.println("1.red\n2.green\n3.blue\n4.black\n5.grey");
         System.out.print("color: ");
         color = sc.nextInt( );
         sc = new Scanner(System.in);
         System.out.println( );
         try{
            sh = new Shoe(brand, size, color);
         }
         catch(ShoeException se){
            System.out.println("Error in creating the shoe");
            System.out.println(se.getMessage( ));
            sc = new Scanner(System.in); //resetting the scanner
         }
      } //ends inner try
      catch(InputMismatchException ime){
         System.out.println("you did not enter a number for either size or color");
         sc = new Scanner(System.in);
      }
      System.out.println(sh.toString( ));
   } //main method
}   //class
