http://forum.java.sun.com/thread.jspa?threadID=5220057
Thanks in advance..+*
This is the Question
Create a class ToyCollection that stores information about different toys in a toy shop.  The information to be stored about a single toy is,
-         Toy identification as String
-         Name of the toy as String
-         Short description about the toy as a String
-         Price of the toy as float
-         Quantity of the toy in hand as short integer.
This class contains following methods,
-         Constructor method that assigns user input values to above mentioned variables.
-         main ( ) method that creates array of 4 objects of ToyCollection class and that takes input for all above details from the user and
calls method to check validity of Quantity and Price values. If all values are valid then create the objects and display the details
for all 4 toys.
-         Method that checks validity of quantity and price. If the quantity is 0 or negative then method should throw user defined
exception with appropriate message and come out of program. Similarly if the price is 0 or negative then it should throw user defined exception with appropriate message and come out of program.
-         Method that displays all details about a single toy in the following format, e.g. Here Total price should be calculated.
Toy Identification                  :  S-1
Toy Name                            :  Small Scooter
Toy Description                    :  Ordinary 3 wheeler scooter
Toy price                              :   650.50
Quantity in hand                    :   3
Total price of Toys               :    1951.50
And i did the following coding
import java.io.*;
import java.lang.*;
public class ToyCollection
     public int toyid;
     public String toyname;
     public String toydetails;
     public float toyprice;
     public int toyquantity;
     public void setToyid(int tid)
          toyid = tid;
     public void setToyname(String tname)
          toyname = tname;
     public void setToydetails(String tdet)     
          toydetails = tdet;
     public void setToyprice(float tpri)
          toyprice = tpri;
     public void setToyquantity(int tquan)
          toyquantity = tquan;
     public int getToyid()
          return toyid;
     public String getToyname()
          return toyname;
     public String getToydetails()     
          return toydetails;
     public float getToyprice()
          return toyprice;
     public int getToyquantity()
          return toyquantity;
     public static void main(String args[])throws Exception
          ToyCollection a=new ToyCollection();
          System.out.println("Enter the Toy id");
          BufferedReader br1=new BufferedReader(new InputStreamReader(System.in));
          int tid=Integer.parseInt(br1.readLine());
          a.setToyid(tid);
          System.out.println("Enter the Toy name");
          BufferedReader br2=new BufferedReader(new InputStreamReader(System.in));
          String tname=br2.readLine();
          a.setToyname(tname);
          System.out.println("Enter the Toy details");
          BufferedReader br3=new BufferedReader(new InputStreamReader(System.in));
          String tdet=br3.readLine();
          a.setToydetails(tdet);
          System.out.println("Enter the Toy price");
          BufferedReader br4=new BufferedReader(new InputStreamReader(System.in));
          float tpri=Float.parseFloat(br4.readLine());
          a.setToyprice(tpri);
          System.out.println("Enter the Toy quantity");
          BufferedReader br5=new BufferedReader(new InputStreamReader(System.in));
          int tquan=Integer.parseInt(br5.readLine());
          a.setToyquantity(tquan);
          System.out.println("The Toy Attributed you entered are displayed below \n" + " ID :" + a.getToyid() + "\n " +" Name :" + a.getToyname() + "\n " + " Details :" + a.getToydetails() + "\n " + " Price :" + a.getToyprice() + "\n " + " Quantity :" + a.getToyquantity());
I submitted the above coding and this was the response from the evaluator
*"You need to create array of toys. You are accepting details of toy in a single line and your program ends."*
Eagerly awaiting your reply at the earliest people.

DrLaszloJamf , here is the question.
Create a class ToyCollection that stores information about different toys in a toy shop. The information to be stored about a single toy is,
- Toy identification as String
- Name of the toy as String
- Short description about the toy as a String
- Price of the toy as float
- Quantity of the toy in hand as short integer.
This class contains following methods,
- Constructor method that assigns user input values to above mentioned variables.
- main ( ) method that creates array of 4 objects of ToyCollection class and that takes input for all above details from the user and
calls method to check validity of Quantity and Price values. If all values are valid then create the objects and display the details
for all 4 toys.
- Method that checks validity of quantity and price. If the quantity is 0 or negative then method should throw user defined
exception with appropriate message and come out of program. Similarly if the price is 0 or negative then it should throw user defined exception with appropriate message and come out of program.
- Method that displays all details about a single toy in the following format, e.g. Here Total price should be calculated.
Toy Identification : S-1
Toy Name : Small Scooter
Toy Description : Ordinary 3 wheeler scooter
Toy price : 650.50
Quantity in hand : 3
Total price of Toys : 1951.50
What is the java code for the above ?
