How can i sort my data with regards to the total number of points, im having difficulty with that!!

can someone help, thanksssssssss

@minus
Have a look at the Comparator interface and the Collections.sort() or Arrays.sort() methods. btw, your 's' key seems to be stuck; fix that.

kind regards,

Actually, the OP's already using that in the class Team - but just look at your compareTo method:

public int compareTo(Team aTeam){
//if 
return 0;
}//end method compareTo() 

Do you know, what this method should be doing?

@Nepomuk
No he isn't; he's using the Comparable interface. A Comparator interface is easier when you want to sort on different criteria.

kind regards,

Ah, sorry, you're right and I'm wrong. I should read more carefully. ^^
