Deleting a Int from my ArrayList

I have a Arraylist: ArrayList<PlayerBean> playerlist = new ArrayList<PlayerBean>();

from an Object that includes a String and an double (Name and points).

 public class PlayerBean{private String name;private double points;}

However for one of my Spinners I want to show only the name (String) in my Arraylist.

How do I manage to delete(remove) the double(points)?

I tried this without any success any ideas?

I am using the swinger for android. any idea?

ArrayList<PlayerBean> playerlist = new ArrayList<PlayerBean>();

List<String> namesOnly = filterNames(playerlist);

private List<String> filterNames(ArrayList<PlayerBean> playerlist12) {
    List<String> names = new ArrayList<String>();
    for(PlayerBean b  : playerlist12)
    {
        names.add(b.getName());

    }
    return names;
}

Rather than removing them, why don't you make a new array List of String type, and assign all the names into this list. So you don't have any points.

Your list contains PlayerBean objects and you can't temporarily delete member variables from objects. Thus you can't remove points from the list.

You could either use a List<String> instead or provide a spinner model that only displays the name. I assume you're using Swing, don't you?
