这个程序打印所有的队名，而不是只打印规则破坏者

Question

    import java.util.HashMap;
    import java.util.Scanner;
    import java.util.TreeSet;

    public class Tamrin1_2_1 {
        public static void main(String[] args) {
            String player,team;
            int numberOfTeams,numberOfPlayers;
            Scanner scanner=new Scanner(System.in);
            HashMap<String,String> teamsAndPlayers=new HashMap<String,String>();
            TreeSet<String> guilty=new TreeSet<String>();
            numberOfPlayers=scanner.nextInt();
            numberOfTeams=scanner.nextInt();
            for(int i=0;i<=numberOfPlayers;i++) {
                teamsAndPlayers.put(scanner.nextLine(), "0");
            }
            for(int i=0;i<numberOfTeams;i++) {
                team=scanner.nextLine();
                numberOfPlayers=scanner.nextInt();
                for(int j=0;j<=numberOfPlayers;j++) {
                    player=scanner.nextLine();
                    if(teamsAndPlayers.containsKey(player)) {
                        if(teamsAndPlayers.get(player).equals("0")) {
                            teamsAndPlayers.put(player, team);
                        }
                        else {
                            guilty.add(team);
                            guilty.add(teamsAndPlayers.get(player));
                         }
                    }
                    else {
                        guilty.add(team);
                    }
                }
            }
            System.out.println(guilty);

            }
        }

但我得到的输出是：

Answer 1

实际上，我会怀疑这些for循环条件：

for(int i=0;i<=numberOfPlayers;i++) {

和

for(int j=0;j<=numberOfPlayers;j++) {

使用<而不是<=。我怀疑现在你对每个团队的解读比要求多了一个名字。

public class Tamrin1_2_1 {
  public static void main(String[] args) {
    String player,team;
    int numberOfTeams,numberOfPlayers;
    Scanner scanner=new Scanner(System.in);
    HashMap<String,String> teamsAndPlayers=new HashMap<String,String>();
    TreeSet<String> guilty=new TreeSet<String>();
    numberOfPlayers=scanner.nextInt();
    numberOfTeams=scanner.nextInt();
    scanner.nextLine();
    for(int i=0;i<numberOfPlayers;i++) {
      teamsAndPlayers.put(scanner.nextLine(), "0");
    }
    for(int i=0;i<numberOfTeams;i++) {
      team=scanner.nextLine();
      numberOfPlayers=scanner.nextInt();
      scanner.nextLine();
      for(int j=0;j<numberOfPlayers;j++) {
        player=scanner.nextLine();
        if(teamsAndPlayers.containsKey(player)) {
          if(teamsAndPlayers.get(player).equals("0")) {
            teamsAndPlayers.put(player, team);
          }
          else {
            guilty.add(team);
            guilty.add(teamsAndPlayers.get(player));
          }
        }
        else {
          guilty.add(team);
        }
      }
    }
    System.out.println(guilty);
  }
}
