I am unable to add an element to a list? UnsupportedOperationException

Question

This one list object is biting me in the butt..

Any time I try to add an element to it, it produces this:

Caused by: java.lang.UnsupportedOperationEx         


        

Answer 1

Arrays.asList() will give you back an unmodifiable list, and that is why your add is failing. Try creating the list with:

AdventureLobbies.players = new ArrayList(Arrays.asList(rs.getString("players").toLowerCase().split(",")));
