I created a console application called FastFood in visual studio 2005. My goal here is to create burgers and consume burgers in a randomized way. It will run like this for 20 times.
Here's my code:
using System;
using System.Collections.Generic;
using System.Text;
namespace FastFood
{
interface Actor
{
void act();}
}
class TooManyPeopleException : Exception
{
public TooManyPeopleException(string message) : base
(message)
{
}
}
class BurgerConsumingException : Exception
{
BurgerConsumingException(string warning) : base(warning)
{
}
class Person : Actor
{
public string name;
public Person(string name)
{
this.name = name;
}
public String getName()
{
return this.name;
}
public void act()
{
Console.WriteLine("This should not appear in the program.");
}
}
class Worker : Person
{
McDonalds job;
public Worker(string name, McDonalds job): base(name)
{
this.name = name;
this.job = job;
}
new public void act()
{
job.Create();
}
class Consumer : Person
{
McDonalds restaurant;
public Consumer(string name, McDonalds restaurant): base(name)
{
this.name = name;
this.restaurant = restaurant;
}
new public void act()
{
try
{
restaurant.Consume();
}
catch(BurgerConsumingException)
{
Console.WriteLine("no more burgers left.");
}
}
}
class McDonalds
{
private int numBurgers = 35;
public List<Person> Customers;
private const int maxSize = 20;
private static Random randomGenerator = new Random();
public McDonalds()
{
Customers = new List<Person>();
Customers.ToString();
}
public void add(Person p)
{
if (Customers.Count <= McDonalds.maxSize)
{
Customers.Add(p);
}
else
{
try
{
throw new TooManyPeopleException("too many people");
}
catch (TooManyPeopleException v)
{
Console.WriteLine("Too many people in Mcdonalds");
}
}
}
public void remove(Person p)
{
}
public void Consume()
{
numBurgers--;
}
public void Create()
{
numBurgers++;
}
public Person getRandomPerson()
{
int i = randomGenerator.Next(Customers.Count+1);
Console.WriteLine("Number generated: " + i);
Person p = (Person) this.Customers[i];
Console.WriteLine(p.getName());
return p;
}
}
}
class Program
{
static void Main(string[] args)
{
Program prog = new Program();
prog.DoThis();
}
public void DoThis()
{
McDonalds mcdo = new McDonalds();
Worker emp1 = new Worker("emp1", mcdo);
Worker emp2 = new Worker("emp1", mcdo);
Worker emp3 = new Worker("emp3", mcdo);
Worker emp4 = new Worker("emp4", mcdo);
Worker emp5 = new Worker("emp5", mcdo);
Consumer buyer = new Consumer("buyer1", mcdo);
Consumer buyer1 = new Consumer("buyer2", mcdo);
Consumer buyer2 = new Consumer("buyer3", mcdo);
Consumer buyer3 = new Consumer("buyer4", mcdo);
Consumer buyer4 = new Consumer("buyer5", mcdo);
Consumer buyer5 = new Consumer("buyer6", mcdo);
mcdo.add(emp1);
mcdo.add(emp2);
mcdo.add(emp3);
mcdo.add(emp4);
mcdo.add(emp5);
mcdo.add(buyer);
mcdo.add(buyer1);
mcdo.add(buyer2);
mcdo.add(buyer3);
mcdo.add(buyer4);
mcdo.add9buyer5);
//runs simulation 20 times
for (int a = 1; a <= 20; a++)
{
Program program = new Program();
program.simulation();
}
}
public void simulation()
{
McDonalds mcdo = new McDonalds();
//Get a random person from Mcdo
//And execute act
//And see how many times you can catch the excpetion when there are no more burgers
mcdo.getRandomPerson();
mcdo.Consume()
mcdo.Create();
Console.ReadKey();
}
}
now my problem is this: whenever I try to run my program, it wont debug and the line "Person p = (Person)this.Cusotmers[i];" will be highlighted in yellow with the warning "ArgumentOutOfRangeException was unhandled."
How can I run it the way its supposed to with putting an exception? I want to see how long it will run the simulation. I'm just a newbie programmer(only three months in programming). Please help!
