Need to print all products from a Stock Manager - Computer Programmers, Programming Forum

JohnDavis32 · #1 10-25-2008

I need to print all of the products from a stock manager application with stock levels below a given value. This is the signature I've been given:

Code:


     public void printInventoryExceptions(int quantity)

Quote:

Note: Not all products should be displayed, only products that are equal or below the quantity specified. Print page headings even if there are no inventory exceptions.

Here is the full code I have so far for the application:

Code:

public class StockManager
{
    private Product[] stock;



    public StockManager(int maxID)
    {
        stock = new Product[maxID];
    }

    

    public Product findProduct(int id)
    {
        return(stock[id]);
    }
    
    public Product findProduct(String name)
    {
        int maxID = stock.length;
        boolean notFound = true;
        Product temp = null;
        for (int i = 0; i < maxID && notFound; i++) {
            if ((stock[i] != null) && (stock[i].getName() == name)) {
                notFound = false;
                temp = stock[i];
            }
        }
        return(temp);
    }



    public int numberInStock(int id)
    {
        int quantity = 0;
        if (stock[id] != null) {
            quantity = stock[id].getQuantity();
        }
        return(quantity);
    }


    public void printProductDetails()
    {
        for (int i=0; i < stock.length; i++) {
            if (stock[i] != null) {
                System.out.println(stock[i]);
            }
        }
    }



    public void addProduct(Product item)
    {
        if (stock[item.getID()] == null){
            stock[item.getID()] = item;
        }
    }
    

    public void delivery(int id, int amount)
    {
        if (stock[id] != null) {
            stock[id].increaseQuantity(amount);
        }       
     }
    

    public Product removeProduct(int id)
    {
        Product temp = stock[id];
        stock[id] = null;    
        return(temp);
    }

Any help would be much appreciated.

I'm assing it's a loop I need to set up, so I have set something up similar to the one earlier in the code:

Code:

public void printInventoryExceptions(int quantity) 
   {
        for (int i=0; i < stock.length; i++) {
            if (stock[i] != null) {
                System.out.println(quantity);
            }
        }
    }

Alright, now this is what I have, but nothing is printing:

Code:

public void printInventoryExceptions(int quantity) 
   {
        for (int i=0; i < stock.length; i++) {
            if (stock[i] != null) {
                System.out.println(stock[i].getQuantity());
            }
        }
    }

Unfortunately, I just found out that this has to do with an "exception report", but we haven't covered it in the BlueJ book yet and I have 9 hours left to figure this out.

Any help would be amazing.

This is the newest code, and it does print something, just not what I need:

Code:

public void printInventoryExceptions(int quantity) 
   {
        int maxID = stock.length;
        boolean notFound = true;
        Product temp = null;
        for (int i = 0; i < maxID && notFound; i++) {
            if ((stock[i] != null)){
                notFound = false;
                temp = stock[i];
                quantity = temp.getQuantity();
            }
        }
        System.out.println("There are " + quantity + " " + " product ID " + stock.length );
    }

The code is now printing "There are 100 product ID 1", which is not what I need, but at least it's printing something. I need it to print anything less than 100 and the name of the product, but I don't know how to add the name of the product.
