排名数组Java

因此，我知道练习的重点是练习使用数组。您已在注释中概述了所需的算法。这是我的实现。

public class RankScores {
    private static int getRank(int[][] scores, int rowIndex, int columnIndex) {
        int count = 0;
        int score = scores[rowIndex][columnIndex];
        for (int row = 0; row < scores.length; row++) {
            for (int col = 0; col < scores[row].length; col++) {
                if (scores[row][col] > score) {
                    count++;
                }
            }
        }
        return count + 1;
    }

    private static int getTeamRank(int[] scores, int index) {
        int count = 0;
        int score = scores[index];
        for (int i = 0; i < scores.length; i++) {
            if (scores[i] > score) {
                count++;
            }
        }
        return count + 1;
    }

    public static void main(String[] args) {
        int referenceScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
        int ranks[][] = new int[referenceScore.length][];
        int totals[] = new int[referenceScore.length]; // total score for each team
        int teamRanks[] = new int[referenceScore.length];
        for (int row = 0; row < ranks.length; row++) {
            ranks[row] = new int[referenceScore[row].length];
            totals[row] = 0;
            for (int col = 0; col < ranks[row].length; col++) {
                ranks[row][col] = getRank(referenceScore, row, col);
                totals[row] += referenceScore[row][col];
            }
        }
        for (int team = 0; team < teamRanks.length; team++) {
            teamRanks[team] = getTeamRank(totals, team);
        }
        System.out.println("          P1     P2     P3     P4     P5     P6   Total Rank");
        for (int row = 0; row < ranks.length; row++) {
            System.out.print("Team " + (row + 1) + " ");
            for (int col = 0; col < ranks[row].length; col++) {
                System.out.printf("%2d(%2d) ", referenceScore[row][col], ranks[row][col]);
            }
            System.out.println(" " + totals[row] + "  " + teamRanks[row]);
        }
    }
}

运行上面的代码将产生以下输出。

         P1     P2     P3     P4     P5     P6   Total Rank
Team 1 39(11) 40( 8) 17(17) 35(13) 42( 1)  6(18)   179   3
Team 2 40( 8) 41( 6) 27(15) 41( 6) 42( 1) 36(12)   227   1
Team 3 42( 1) 40( 8) 26(16) 42( 1) 42( 1) 35(13)   227   1
