    Default For/Array Problem: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

    I want to add a player to a team, and delete this player from other teams, so that the player is not in 2 teams at the same time.

    I really dont know why this is giving me an error. (Error:
    HTML Code:
    java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
    )

    public static void addPlayertoTeam(Player p, int teamnumber) {      
     
          print.c("Adding player to team..");
     
          if (Check.getTeamMembers(teamnumber).size() != Check.getPperTeam()) {
          print.c("Player can be added. Checking other teams..");  
           for(int i=0; i < Check.getTeamAnzahl(); i++) {
            if (Check.getTeamMembers(i+1).size() != 0) {
            print.c("Check-Team is not empty.");
             for (int j=0; j < Check.getTeamMembers(i+1).size(); j++) {
              if (Check.getTeamMembers(i+1).get(j+1) == p.getName()) {
               print.c("Player found. Removing player..");
              }
             }
            }
           }
          }

    java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
    That says the code tried to use an index of 1 (requires at least 2 items) in a list or array that only had 1 item (MAX INDEX OF 0)
    Check the code to see why it is using an invalid index.
    If you don't understand my answer, don't ignore it, ask a question.

    I know, but can you tell me what exactly is wrong with my code?

    what exactly is wrong with my code?
    It is using an index that is past the end of the list.
    There aren't any comments describing what the code is trying to do so I can't point to a statement that is not doing what it is supposed to as described in the comments.

    It would help for reading the code if the indentations were more that one space. Poorly formatted code is hard to read.

    What is the index that has the value that is past the end of the list?
    Add some print statements that print out the value of the index and the length/size of the list it is being used with.
    The print out should should you where the index is wrong for the size of the list.
    If you don't understand my answer, don't ignore it, ask a question.
