我正在尝试对我的作业中的数组进行排名,但我不理解如何做。有人可以帮帮我吗?提前谢谢您。

我附上了完整作业说明的图片。

这是我的作业图片:

这是我的代码:

public class Assignment_3_Question_1 {
// 这里,我预先定义了我的数据集。
static int referenceScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
static int finalScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
static int scoreAmongOthers[][]=new int[3][6];
static int max;
static int rank = 1;
static int count = 0;
static int total = 0;
public static void main(String[] args) {
for (int k = 0; k < 10; k++){
max = referenceScore[0][0];
for (int team = 0; team < 3; team++){
for (int position = 0; position < 6; position++){
if (max < referenceScore[team][position]){
max = referenceScore[team][position];
}
}
}
for (int x = 0; x < 3; x++){
for(int y = 0; y < 6; y++){
if(referenceScore[x][y]==max){
scoreAmongOthers[x][y]=rank;
referenceScore[x][y]=0;
count++;
}
}
}
rank = count + 1;
}
// 打印出
System.out.println("\tP1\tP2\tP3\tP4\tP5\tP6\tTotal\tRank");

    // 打印出每个团队的结果和排名
    for(int teamNb = 0; teamNb<3; teamNb++){
        System.out.print("Team"+(teamNb+1));
        for(int p=0; p<6; p++){
            total = total + finalScore[teamNb]

; System.out.print("\t" + finalScore[teamNb]

+"("+ scoreAmongOthers[teamNb]

+") "); } System.out.print("\t"+ total); total = 0; System.out.println(); } }

}

I am trying to rank my array in my assignment but I don't understand how to do it. Can someone help me? Thank you in advance

I added an image of the full assignment instructions.

Here is an image of my assignment:

排名数组 Java

And here is my code:

public class Assignment_3_Question_1 {
	// Here, I predefined my data set.
	static int referenceScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
	static int finalScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
	static int scoreAmongOthers[][]=new int[3][6];
	static int max;
	static int rank = 1;
	static int count = 0;
	static int total = 0;
	public static void main(String[] args) {
		for (int k = 0; k &lt; 10; k++){
			max = referenceScore[0][0];
			for (int team = 0; team &lt; 3; team++){
				for (int position = 0; position &lt; 6; position++){
					if (max &lt; referenceScore[team][position]){
						max = referenceScore[team][position];
					}
				}
			}
			for (int x = 0; x &lt; 3; x++){
				for(int y = 0; y &lt; 6; y++){
					if(referenceScore[x][y]==max){
						scoreAmongOthers[x][y]=rank;
						referenceScore[x][y]=0;
						count++;
					}
				}
			}
			rank = count + 1;
		}
		// Print out the  
		System.out.println(&quot;\tP1\tP2\tP3\tP4\tP5\tP6\tTotal\tRank&quot;);
		
		// Prints out the results and the rank for each team
		for(int teamNb = 0; teamNb&lt;3; teamNb++){
			System.out.print(&quot;Team&quot;+(teamNb+1));
			for(int p=0; p&lt;6; p++){
				total = total + finalScore[teamNb]

; System.out.print(&quot;\t&quot; + finalScore[teamNb]

+&quot;(&quot;+ scoreAmongOthers[teamNb]

+&quot;) &quot;); } System.out.print(&quot;\t&quot;+ total); total = 0; System.out.println(); } } }

以下是翻译好的内容:

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]);
        }
    }
}

上述代码运行后产生以下输出:

          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

So I understand that the point of the exercise is to practice working with arrays. You have outlined the required algorithm in your comment. Here is my implementation.

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 &lt; scores.length; row++) {
            for (int col = 0; col &lt; scores[row].length; col++) {
                if (scores[row][col] &gt; 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 &lt; scores.length; i++) {
            if (scores[i] &gt; 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 &lt; ranks.length; row++) {
            ranks[row] = new int[referenceScore[row].length];
            totals[row] = 0;
            for (int col = 0; col &lt; ranks[row].length; col++) {
                ranks[row][col] = getRank(referenceScore, row, col);
                totals[row] += referenceScore[row][col];
            }
        }
        for (int team = 0; team &lt; teamRanks.length; team++) {
            teamRanks[team] = getTeamRank(totals, team);
        }
        System.out.println(&quot;          P1     P2     P3     P4     P5     P6   Total Rank&quot;);
        for (int row = 0; row &lt; ranks.length; row++) {
            System.out.print(&quot;Team &quot; + (row + 1) + &quot; &quot;);
            for (int col = 0; col &lt; ranks[row].length; col++) {
                System.out.printf(&quot;%2d(%2d) &quot;, referenceScore[row][col], ranks[row][col]);
            }
            System.out.println(&quot; &quot; + totals[row] + &quot;  &quot; + teamRanks[row]);
        }
    }
}

Running the above code produces the following output.

          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
