Help with restaurant program (Inheritance related)

I am trying to make a program which is a restaurant ordering system. But cannot get it to compile.

here are the java files I am using.

drink.java

Quote:

import java.util.*;

public class Drink extends Order
{
private int ID;
private int name;

public Drink(int ID , String Name)
{
this.ID = ID;
this.name = name;
Drink one = new Drink();
Drink two = new Drink();
one.name = "Red Wine 750ml";
two.name = "Mineral Water 1.5l";
}

public int getID ()
{
return ID;
}
public String getName()
{
return name;
}
}

food.java

Quote:

import java.util.*;

public class Food extends Order
{
private int id;
private int name;

public Food(int id, String name)
{
this.id = id;
this.name = name;
Food one = new Food();
Food two = new Food();
one.name = "Steak with Potatoes";
two.name = "Pasta Salad";
}
public int getID()
{
return id;
}
public String getName()
{
return name;
}
}

Orders.java

Quote:

public class Orders
{
private String command;

public Orders(String command)
{
this.Orders = newOrder();
}
}

restaurant.java

Quote:

import java.util.*;
import cs1.*;

public class Restaurant {
public static void main(String[] args) {

Locale.setDefault(Locale.UK); // So monetary output uses £

Orders orders = new Orders();

Menu m1 = new Menu();
boolean nextCustomer = false;
String response;

m1.addItem("Red Wine 750ml", 11.50);
m1.addItem("Mineral Water 1.5l", 1.50);
m1.addItem("Steak and Potatoes", 9.00);
m1.addItem("Pasta Salad", 7.80);

Waiter w1 = new Waiter("Kevin");

do{
Customer c = new Customer(m1);
orders.addCustomer(c);
s1.greet();
s1.serve(c, m1);
System.out.print("Next customer? (y/n): ");
response = Keyboard.readString();
nextCustomer = response.equals("y");
} while (nextCustomer);

orders.displayOrders();
orders.displayTotal();
}
}

It would help if you said what the compiler errors were, as "import cs1.*;" means we can't test compile it ourselves.

Code:

public class Drink extends Order
{
private int ID;
private int name;

public Drink(int ID , String Name)
{

I don't know if this would be a problem, but after looking at this quickly.... since Java is case-sensitive, it might be a problem that "Name" is capitalized in the "public Drink" line but it's just "name" when you initialize it at first....

so maybe...

Code:

public class Drink extends Order
{
private int ID;
private String name;

public Drink(int ID , String name)

would work....

Note that I also made "name" a string when it's initialized, instead of an int.

But hey, I'm a tooootal noooob. I hope this helps though ^_^

tictactactics ir right. Also:
public class Orders
{
private String command;

public Orders(String command)
{
this.Orders = newOrder();
}
}

Also there is no member (attribute) on the Orders class named Orders to assign the newOrder() result to. These errors were certainly caught by the compiler and the reasons for compilation failure given.
