价格是正确的程序.需要将字符串分成几部分，并将失败的玩家替换为数组中的其他玩家

Question

我对这个程序有几个问题(它还没有完成(。我有一个名为 player 的字符串，它打印从 20 个玩家的数组中选择的 4 个随机玩家。我需要一种方法将它们分成单独的名称，而无需使用 split 命令(尚未在课堂上学习(。此外，我需要一种方法来用新玩家替换价格正确的游戏的失败者。因此，如果总共有 4 名玩家，并且 1 名是赢家，我需要用数组中的 3 名新人替换 3 名输家。最后，我需要一种方法，当数组从 20 个人中随机选择时，不会重复玩家。提前感谢大家！

您可以使用它来拆分播放器字符串。

    String 4players = Arrays.toString(playerarray);
    String[] splited = 4players.split(","); // use the symbol that seperates the players 
    for(String s : splited)
    System.out.println(s.trim());
