Question

I’m trying to make a java application that’s allows the user to make a catalog for a supermarket, and then display all the products that the user entered to the catalog. Now I have a problem with filling the array of objects the should be fill in by the user’s input.
The output should be like the following (user input in Bold):

Enter product description (or # to stop): Condensed Powdered water
Enter product code: P3487
Enter product unit price: $2.50
Enter product unit phrase: per packet

Enter product description (or # to stop): Distilled Moonbeams
Enter product code: K3876
Enter product unit price: $3.00
Enter product unit phrase: a dozen

Enter product description (or # to stop): Anti-Gravity Pills
Enter product code: Z9983
Enter product unit price: $12.75
Enter product unit phrase: for 60

Enter product description (or # to stop): #

Your catalog:
P3487, Condensed Powdered water, $2.50 per packet.
K3876, Distilled Moonbeams, $3.00 a dozen.
Z9983, Anti-Gravity Pills, $12.75 for 60.

The code that I wrote : 2 classes
class 1:

public class Catalog {

private String description ; 
private String code ;
private double price ;
private String phrase ;

int counter = 0;

private Catalog [] list = new Catalog [100];

public Catalog (String productDescription , String productCode , double    productPrice , String productPhrase)
{
    description = productDescription;
    code = productCode;
    price = productPrice;
    phrase = productPhrase;
}

public void setDescription (String productDescription)
{
    description = productDescription;
}

public String getDescription ()
{
    return description;
}

public void setCode (String productCode)
{
    code = productCode;
}

public String getCode ()
{
    return code;
}

public void setPrice (double productPrice)
{
    price = productPrice;
}

public double getPrice ()
{
    return price;
}

public void setPhrase (String productPhrase)
{
    phrase = productPhrase;
}

public String getPhrase ()
{
    return phrase;
}

class 2:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class CatalogTest {

/**
 * @param args
 * @throws IOException 
 */

public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub

    String name = null; 
    String code = null;
    double price = 0.0;
    String phrase = null;



    BufferedReader input = new BufferedReader (new InputStreamReader  (System.in));

    Catalog product = new Catalog(name,code,price,phrase);

    Catalog [] productsArray = new Catalog [100];


    for (int i = 0 ; i < productsArray.length ; i ++)
    {


        System.out.println("Enter product description (or # to stop): ");
        name = input.readLine();

        if (!("#".equals(name))) 
        {

            productsArray [i] = product;
            product.setDescription(name);

            System.out.println("Enter product code: ");
            code = input.readLine();
            productsArray [i] = product;
            product.setCode(code);


            System.out.println("Enter product unit price: ");
            price = Double.parseDouble(input.readLine());
            productsArray [i] = product;
            product.setPrice(price);


            System.out.println("Enter product unit phrase: ");
            phrase = input.readLine();
            productsArray [i] = product;
            product.setPhrase(phrase);



            productsArray [i] = new Catalog (name,code,price,phrase);



        }

        else 
        {
            System.out.println("Your Catalog:");

            System.out.printf("%s, %s,$%.2f   %s",product.getCode(),product.getDescription(),product.getPrice(),product
                    .getPhrase());
            break;
        }


    }


}
}

The output I get (user input in Bold) :
Enter product description (or # to stop):
condensed powdered water
Enter product code:
p3487
Enter product unit price:
2.50
Enter product unit phrase:
per packet
Enter product description (or # to stop):
distilled moonbeams
Enter product code:
k3876
Enter product unit price:
3
Enter product unit phrase:
a dozen
Enter product description (or # to stop):
#
Your Catalog:
k3876, distilled moonbeams,$3.00 a dozen

So any help PLEASE ??

Answer 1

Here is the updated code that works…

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CatalogTest
{

    /**
     * @param args
     * @throws IOException
     */

    public static void main(String[] args) throws IOException
    {
        // TODO Auto-generated method stub

        String name = null;
        String code = null;
        double price = 0.0;
        String phrase = null;

        BufferedReader input = new BufferedReader(new InputStreamReader(
            System.in));

        Catalog product = new Catalog(name, code, price, phrase);

        Catalog[] productsArray = new Catalog[100];

        for (int i = 0; i < productsArray.length; i++)
        {

            System.out.println("Enter product description (or # to stop): ");
            name = input.readLine();

            if (!("#".equals(name)))
            {

                productsArray[i] = product;
                product.setDescription(name);

                System.out.println("Enter product code: ");
                code = input.readLine();
                productsArray[i] = product;
                product.setCode(code);

                System.out.println("Enter product unit price: ");
                price = Double.parseDouble(input.readLine());
                productsArray[i] = product;
                product.setPrice(price);

                System.out.println("Enter product unit phrase: ");
                phrase = input.readLine();
                productsArray[i] = product;
                product.setPhrase(phrase);

                productsArray[i] = new Catalog(name, code, price, phrase);

            }

            else
            {
                System.out.println("Your Catalog:");
                for (int j = 0; j < productsArray.length; j++)
                {
                    if(productsArray[j]!=null)
                    {
                        System.out.printf("%s, %s,$%.2f %s,",
                            productsArray[j].getCode(),
                            productsArray[j].getDescription(),
                            productsArray[j].getPrice(),
                            productsArray[j].getPhrase());
                    }
                }
                break;
            }

        }

    }
}
