Is there ant way to sort a generic ArrayList? I have a PlayerBean that includes fist name and stats I want to sort it by first name any idea? With a String array it was simple Collections.sort(list)...

 public class PlayerBean {
    private String name;
    private int stat1;
    private Double stat2;
    private Double stat3;
    private Double stat4;

        ....
 }

have a look at http://docs.oracle.com/javase/6/docs/api/java/util/Collections.html#sort(java.util.List, java.util.Comparator) — andbi, Mar 14 '12 at 19:29

Use the same method with a specialized comparator:

 new Comparator<PlayerBean>() {

       @Override
       public int compare(PlayerBean o1, PlayerBean o2) {
           return o1.getName().compareTo(o2.getName());
       }                
 }
