for (int i = 1; i < GPlayers.length; i++)
System.out.println("enter player name : ");
nameIn = sc.next();
GPlayers.setplayerName(nameIn);
return GPlayers;

Answer 1

You created the array, but all elements of it are still null.
The loop should probably be 0..< GPlayers.length.
After you read a name, do:
GPlayers[i] = new player(); // add constructor parameters as necessary.Please use code tags (see button above posting box), so that the [ i ] in your code doesn't cause italics. You can't underline in code tags, but you can put a comment next to the line as I did.
