Testing a arraylist for the same string

[ben riches]

Hello all i an array list with the following inside it

[ben, ben, Names, name, name, mum, mum, mum, mum, mum]

I want to be able to get the output like this
ben
Names
name
mum
so what should happen, is that it test the arraylist for dublicates and only pulls out one of each. if you understand what I mean.
Thanks
Ben

What have you tried so far? Which part is giving you trouble?
When asking folks a question, taking a minute to first explain things to your Cardboard Analyst and to think about Asking a Good Question is time well spent.

Use a set, which can contain no duplicates. See Set, HashSet, and perhaps TreeSet in java.util.

Make an array in which you copy the unique elements and print its contents.
But, Dirk is right: Give these problems some thought yourself, that way you'll learn a lot faster...

Here's one way

import java.util.*;
class Test
{
  public Test()
  {   
    ArrayList list = new ArrayList(Arrays.asList(new String[]{
      "ben", "ben", "Names", "name", "name", "mum", "mum", "mum", "mum", "mum"}));
    for(int x = 0; x < list.size(); x++)
    {
      if(list.indexOf(list.get(x).toString()) == x) System.out.println(list.get(x).toString()); 
    }
    System.exit(0);
  }
  public static void main(String[] args){new Test();}
}
