Question

Create a program that simulates a pack of eight Crayons (an array of objects). Each crayon should have a color (red, yellow, green, blue, brown, black, orange and purple), length in millimeters and sharpness (a number between 1 and 5). The user wants to be able to randomly select a crayon and then be presented with the color, length and sharpness (no one likes a dull crayon). Let the user randomly select three Crayons. The same color Crayon cannot be select more than once. (Crayon.java) (13 pts) The user should also be able to view all of the Crayons (color, length and sharpness) in a menu as an alternative to the random selection. Extra-Credit: The user should be able to exit the program at any time by typing ‘end’(IN JAVA

Explanation / Answer

PROGRAM CODE:

package util;

import java.util.ArrayList;
import java.util.Random;
import java.util.Scanner;

public class CrayonChooser {

   public static void main(String[] args) {
       ArrayList<Crayon> packOfCrayons = new ArrayList<>();
       packOfCrayons.add(new Crayon("Blue", 10, 3));
       packOfCrayons.add(new Crayon("Yellow", 10, 3));
       packOfCrayons.add(new Crayon("Red", 10, 3));
       packOfCrayons.add(new Crayon("Black", 10, 3));
       packOfCrayons.add(new Crayon("Green", 10, 3));
       packOfCrayons.add(new Crayon("Orange", 10, 3));
       packOfCrayons.add(new Crayon("Pink", 10, 3));
       packOfCrayons.add(new Crayon("Brown", 10, 3));
      
       Scanner keyboard = new Scanner(System.in);
       Random random = new Random();
       while(true)
       {
       String choice;
       System.out.println(" Show - Show a crayon View - view all crayons End - End the program Enter your choice");
       choice = keyboard.next();
       if(choice.equalsIgnoreCase("end"))
           System.exit(0);
       else if(choice.equalsIgnoreCase("show"))
       {
           if(packOfCrayons.size()>0)
           {
               int rand = random.nextInt(packOfCrayons.size());
               System.out.println(packOfCrayons.get(rand));
               packOfCrayons.remove(rand);
           }
       }
       else if(choice.equalsIgnoreCase("view"))
       {
           for(int i=0; i<packOfCrayons.size(); i++)
               System.out.println(packOfCrayons.get(i));
       }
       }
   }

}
