Java linked list

English · 05-01-2003, 06:17 PM

Jesus, any1 do java? Im used to using pointers. Im trying to do a linked list, but I cant get my head around it.

Here is my code to return the number of items in the list.

Code:

public int cardinality()
          {
            int count = 0;
            word temp = this.FirstWord;

             do
             {
                count++;
                temp = temp.returnNext();
             }while (temp!=null);


            return count;
          };

The line

Code:

temp = temp.returnNext();

Seems to be messing up the list, as it sets whats in temp, to equal whats in the next item. Where as I just want to point to that new item. Yes?

Im used to using C, where u can use pointers for everything. Does any1 know a way of doing it?

Morat, i think u program, help me.

Forget it, ive sorted it....

I forgot to set the last element of the list to the new element. The list wasnt growing.

1 line of code == 2 hours of pulling ur hair out.

Stay away from programming.
