Question

Can anyone help, please:

You have decided to use a specialized toy company to purchase birthday gifts for young children of your friends and relatives. The available toys are divided into three categories: plushies, blocks, and books. In addition, you can add a card and/or a balloon with each gift.

You must utilize the provided Toy class for this project, without making any changes to it (study and review the class carefully.) The class will keep a total cost for one toy and determine if the toy is age-appropriate for the child. Assume that the user enters the name and age of the child correctly.

Your program must print a title and a list to the console of all the gifts, with a total for each gift, and the total amount of the order. Then your program must generate a random five-digit order number as an order number.

·       All input items and messages will use dialog boxes (JOptionPane). Only the title, list of gifts, total, and order number are printed on the console. (See sample output.)

·       Ask for the name of the child.

·       Ask for the age of the child. . (A child should be under 18? You decide)

·       Ask for the toy choice and validate the input choicePrint out a message if the toy is not age appropriate and ask if a different toy is desired. Otherwise, print the message "Good Choice!"

·       If the user does not want a different toy, process the toy requested. Otherwise, repeat the steps for a new toy choice.

·       Ask if a card or balloon should be added to the gift.

·       If a card is added, capture the card message

·       Display on the console the name, age, “gift card” message and the total for gift.

·       Ask if another gift is desired. If yes, repeat the steps starting with the name of the child.

·       If no, display on the console the total amount of the order and the random five-digit order number.

·       Any amount should be displayed (on the console) as US currency format (e.g. $15.43).

·       Name your driver class Birthday

·       Input validations are expected

·       Javadoc should be generated

·       UML class diagram(s) must be created

I just need the class and driver

Explanation / Answer

Solution for the Given Problem

I written this below TestToy Driver class to test the given java program called Toy with sample plushie..
And it is working fine with the below code and i tested also.

public class TestToy
{
   public static void main(String[] args)
   {
       Toy obj = new Toy("plushie",2);
       boolean flag = obj.ageOK();
       obj.addCard("yes");
       obj.addBalloon("yes");
       System.out.println(obj);
   }
}
