如何找到多个数组中的最大值和 return java 中第一个索引的值？

Question

我的代码打印出不同玩家的列表，我想找出哪个列表的总价值最高。我希望玩家的名字打印在 Top: Gamer.

行中 table 值的下方

public static void main(String[] args) throws IOException {

        File gameScores = new File("C:\Users\jaret\OneDrive\Desktop\GameScores.csv");
        if (gameScores.exists()) {
            BufferedReader br = null;
            String line = "";
            String csvSplitBy = ",";
            int gamerCount = 0;
            br = new BufferedReader(new FileReader(gameScores));
            System.out.println("----------------------------------------------------------");
            System.out.println("-------------------------------------");
            System.out.println("Games Report");
            System.out.println("----------------------------------------------------------");
            System.out.println("-------------------------------------");
            System.out.println("Gamer   1   2   3   4   5   6   7");
            System.out.println("    8   9   10  Total");
            System.out.println("----------------------------------------------------------");
            System.out.println("-------------------------------------");

            while ((line = br.readLine()) != null) {
                String list[] = new String[10];
                list = line.split(csvSplitBy);
                int sum = 0;

                for (String element : list) {
                    try {
                        Integer num = Integer.parseInt(element);
                        sum += num;
                    } catch (NumberFormatException nfe) {
                        System.out.print(list[0] + "\t" + list[1] + (list[1].length() > 10 ? "\t" : "\t") + list[2]
                                + (list[2].length() > 10 ? "\t" : "\t") + list[3]
                                + (list[3].length() > 10 ? "\t" : "\t") + list[4]
                                + (list[4].length() > 10 ? "\t" : "\t") + list[5]
                                + (list[5].length() > 10 ? "\t" : "\t") + list[6]
                                + (list[6].length() > 10 ? "\t" : "\t") + list[7]
                                + (list[7].length() > 10 ? "\n\t" : "\n\t") + list[8]
                                + (list[8].length() > 10 ? "\t" : "\t") + list[9]
                                + (list[9].length() > 10 ? "\t" : "\t") + list[10] + "\t");
                    }
                }
                System.out.println(sum);
                gamerCount++;
            }

            System.out.println("----------------------------------------------------------");
            System.out.println("-------------------------------------");
            System.out.println("# of Gamers:    " + gamerCount);
            System.out.println("Top Gamer:  ");
            br.close();
        }

        String newGamer;
        newGamer = userInput();
        enterGamer(newGamer);
    }

这是我的输出：

Answer 1

您需要记录最高分以及得分最高的游戏名称。以下应该有效：

public static void main(String[] args) throws IOException {

    File gameScores = new File("C:\Users\jaret\OneDrive\Desktop\GameScores.csv");
    if (gameScores.exists()) {
        BufferedReader br = null;
        String line = "";
        String csvSplitBy = ",";
        int gamerCount = 0;
        int topScore = 0;
        String topScorer = "";
        br = new BufferedReader(new FileReader(gameScores));
        System.out.println("----------------------------------------------------------");
        System.out.println("-------------------------------------");
        System.out.println("Games Report");
        System.out.println("----------------------------------------------------------");
        System.out.println("-------------------------------------");
        System.out.println("Gamer   1   2   3   4   5   6   7");
        System.out.println("    8   9   10  Total");
        System.out.println("----------------------------------------------------------");
        System.out.println("-------------------------------------");

        while ((line = br.readLine()) != null) {
            String list[] = new String[10];
            list = line.split(csvSplitBy);
            int sum = 0;

            for (String element : list) {
                try {
                    Integer num = Integer.parseInt(element);
                    sum += num;
                } catch (NumberFormatException nfe) {
                    System.out.print(list[0] + "\t" + list[1] + (list[1].length() > 10 ? "\t" : "\t") + list[2]
                            + (list[2].length() > 10 ? "\t" : "\t") + list[3]
                            + (list[3].length() > 10 ? "\t" : "\t") + list[4]
                            + (list[4].length() > 10 ? "\t" : "\t") + list[5]
                            + (list[5].length() > 10 ? "\t" : "\t") + list[6]
                            + (list[6].length() > 10 ? "\t" : "\t") + list[7]
                            + (list[7].length() > 10 ? "\n\t" : "\n\t") + list[8]
                            + (list[8].length() > 10 ? "\t" : "\t") + list[9]
                            + (list[9].length() > 10 ? "\t" : "\t") + list[10] + "\t");
                }
            }
            if (sum > topScore) {
                topScore = sum;
                topScorer = list[0];
            }
            
            System.out.println(sum);
            gamerCount++;
        }

        System.out.println("----------------------------------------------------------");
        System.out.println("-------------------------------------");
        System.out.println("# of Gamers:    " + gamerCount);
        System.out.println("Top Gamer:  " + topScorer);
        br.close();
    }

    String newGamer;
    newGamer = userInput();
    enterGamer(newGamer);
}
