有人能告诉我为什么在游戏结束时获胜者打印出 4 次吗？ （Java，简单的 21 点游戏）

Question

输出请参考图片。我的代码能够组织适当的分数，然后根据条件选择获胜者。获胜者不得超过 21，并且获胜者不能出现平局。如果有 21 & 21 那么没有人赢。但是，如果有 24 24 21 19，则 21 获胜。 （添加 bc 堆栈需要更多细节）

如果有人能指出为什么我的程序打印出 4 个同一个获胜者的陈述，我将不胜感激。

This is my code for the section: 

/**
     * Determines who won the game, and prints the results.
     */
    public void printWinner() { 
        // Students: your code goes here.
        int[] arr = {this.human.getScore(), this.player1.getScore(), this.player2.getScore(), this.player3.getScore()};
        Arrays.sort(arr);
        for (int num : arr) {
            if (arr[3] != arr[2] && arr[3] <= 21) {
                if (arr[3] == human.getScore()) {
                    System.out.println(human.name + " wins with " + arr[3] + " points!");
                }
                if (arr[3] == player1.getScore()) {
                    System.out.println(player1.name + " wins with " + arr[3] + " points!");
                }
                if (arr[3] == player2.getScore()) {
                    System.out.println(player2.name + " wins with " + arr[3] + " points!");
                }
                if (arr[3] == player3.getScore()) {
                    System.out.println(player3.name + " wins with " + arr[3] + " points!");
                }
        }
            else if (arr[3] == arr[2] && arr[3] <= 21) {
                System.out.println("Tie, nobody wins.");}
            
            else if (arr[3] == arr[2] && arr[3] > 21) {
                if (arr [1] <= 21 && arr[1] != arr[0]) {
                    if (arr[1] == human.getScore()) {

                    }
                if (arr[1] == player1.getScore()) {
                        System.out.println(player1.name + " wins with " + arr[1] + " points!");
                    }

在检测获胜者方面效果很好，唯一的问题是同一个指定的获胜者打印了 4 次。

我只是不确定我需要编辑什么才能只打印一次结果。
