Having hard time getting this to work.

Question

Hi
I have been working on this for several hours now and not having much luck. I think im not understanding the relationship between the two classes properly. Also there is a GUI that goes with it but it only so fay has the code to construct the GUI. My problem is getting these two classes to compile, then mabe i can move on to finishing the GUI. If you need the GUI then i can post it.
If you could, please take a look at these two classes that im having trouble with, where am i going wrong.......
import java.util.*;
     public class ShoppingCart     {
private Product[] shoppingcart;
private static int count;
public void shoppingCart()     {
shoppingcart = new Product[50];
     count = 0;
public void addProduct(String name, double price, int quantity) {
boolean found = false;
int i = 0;
while(i < count)
if(shoppingcart.getName().equals(name)) //tests for existing entry.
found = true;
break; // break form loop if true.
i++;
     // adds retrieves corresponding number for entry.
if(found == true)
shoppingcart[i].setPrice(price);
// adds new entry.
else {
if(count < shoppingcart.length)     {
shoppingcart[count++] = new Product(name, price, quantity);
else {
Product[] temp = new Product[shoppingcart.length*2];
for (int j = 0; j < shoppingcart.length; i++)
temp[j] = shoppingcart[j];                                   
temp[count++] = new Product(name, price, quantity);
shoppingcart = temp;
          public String findProduct(String name)     {
for (int i = 0; i < count ; i++)
if(shoppingcart[i].getName().equals(name))
return shoppingcart[i];
return "Not found.";
I think i will post the other class below.....

Answer 1

This is the second class.
Explanation. With a working GUI this program will add and retrieve different products, two events are required, add/modify and search. new products are added to an array with three parameters name, price and quantity. These product need to be able to be called up and stored into a text area displaying name, price and quantity.
Any help is appreciated.
public class Product {
private String name;
private double price;
private int quantity;
public Product(String name, double price, int quantity)     {
          this.name = name;
               //price = 0.00;
               quantity = 0;
               //this.name = name;
this.price = price;
public String getName()     {
return name;
public double getPrice()     {
return price;
public int getQuantity()     {
return quantity;
          public void setName(String name)     {
          name = name;
          public void setPrice(double price)     {
          //price = price;
          public void setQuantity(int quantity)     {
          quantity = quantity;
}
