I have an array of strings plus one additional string. I want to use this string and values of array to get a set of string. Then I want to order the set of string alphabetically and extract the string which is the first in the list. What is the easiest way to do it in Java?
ADDED:
I wanted to do it this way:
List<String> playersList = Arrays.asList(players);
playersList.add(userName); // <---------- HERE IS A PROBLEM
Collections.sort(playersList);
I do not get any errors during the compilation. But during the execution I get a "UnsopportedOperationException". And it happens in the second line.
