I am using c# language and doing this on console based application. The problem i am having is sorting. i need to produce two things. first is sorting alphabetically, second is sorting numerically. I add products and quantity myself so there is no fixed arraylist as such. i want to know how to sort it based on what i enter into the console. does this make sense?

C#

     public class TheoVendingMachine
  {
      private ArrayList merchandises;
      public MoneySet moneys;
      public MoneySet currentMoneys;
      public TheoVendingMachine()
      {
          this.merchandises = new ArrayList();
          this.moneys = new MoneySet();
          this.currentMoneys = new MoneySet();
      }
      public Merchandise[] getProductTypes()
      {

          ArrayList arrayList = new ArrayList();
          arrayList.Sort();
          foreach (Merchandise product in this.merchandises)
          {
              if (!arrayList.Contains(product))
              {
                  arrayList.Add(product);
              }

          }

Merchandise[] array = new Merchandise[arrayList.Count];

          for (int i = 0; i < arrayList.Count; i++)
          {
              array[i] = (Merchandise)arrayList[i];
              arrayList.Sort();
          }


          return array;
      }

What you enter in the console is always text - so if you want to sort things numerically, you need to convert the text to a number:

C#

string s = Console.ReadLine();
int i;
if (int.TryParse(s, out i))
   {
   // Valid integer entered
   ...
   }
else
   {
   // Tell the user that isn't a number...
   ...
   }

And I wouldn't use an ArrayList - use a typed array or List<T> - that way you don;t have to cast it to the desired type before you use it.
So...Set up either a class to contain the string and integer value together then use a List<T>of that class, or set up two Lists (one of string and one of int) and sort them appropriately.

You know how to do that, yes?
