9333,12,120,2,1
PRINT
9533,5,45,0,0
8573,10,120,1,0
6343,6,18,170,0
PRINT
9311,12,120,2,1

    public String toString() {
        return player_ID + "," + total_score;

        for (FantasyPlayers str : Stats) 
        {
                System.out.println(str);
        }
        Collections.sort(Stats, new Comparator<FantasyPlayers>()
            {
            public int compare(FantasyPlayers one, FantasyPlayers two)
            {
                if (one.total_score == two.total_score){
                    Integer playerOne = one.player_ID;
                    Integer playerTwo = two.player_ID;

                    return playerTwo.compareTo(playerOne);
                }
                Integer scoreOne = one.total_score;
                    Integer scoreTwo = two.total_score;

                return scoreTwo.compareTo(scoreOne);
                }
        });
        System.out.println("Ordered");
        for (FantasyPlayers str : Stats) 
        {
            System.out.println(str);
        }

     }

}

我在 int Score = 位置不断收到错误 ArrayIndexOutOfBoundsException:1。

我的问题是如何处理代码中的 PRINT 语句...我可以对数据执行我想要的操作，但是当我读取 print 语句时，我需要逻辑来执行某些操作。有什么建议吗？

你，我的 friend ，陷入了最常见的 java 错误......

试试这个

   if (!line.equalsIgnoreCase("PRINT"))
