问题

以下是翻译好的部分：

  1. 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。
  3. 我附上了完整作业说明的图片。
  5. 这是我的作业图片：
  7. [![enter image description here][1]][1]
  9. 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");

  1.     // 打印出每个团队的结果和排名
  2.     for(int teamNb = 0; teamNb<3; teamNb++){
  3.         System.out.print("Team"+(teamNb+1));
  4.         for(int p=0; p<6; p++){
  5.             total = total + finalScore[teamNb]
    ;
  6.             System.out.print("\t" + finalScore[teamNb]
    +"("+ scoreAmongOthers[teamNb]
    +") ");
  7.         }
  8.         System.out.print("\t"+ total);
  9.         total = 0;
  10.         System.out.println();
  11.     }
  12. }

}

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:

以下是翻译好的内容：

  1. public class RankScores {
  2.     private static int getRank(int[][] scores, int rowIndex, int columnIndex) {
  3.         int count = 0;
  4.         int score = scores[rowIndex][columnIndex];
  5.         for (int row = 0; row < scores.length; row++) {
  6.             for (int col = 0; col < scores[row].length; col++) {
  7.                 if (scores[row][col] > score) {
  8.                     count++;
  9.                 }
  10.             }
  11.         }
  12.         return count + 1;
  13.     }
  15.     private static int getTeamRank(int[] scores, int index) {
  16.         int count = 0;
  17.         int score = scores[index];
  18.         for (int i = 0; i < scores.length; i++) {
  19.             if (scores[i] > score) {
  20.                 count++;
  21.             }
  22.         }
  23.         return count + 1;
  24.     }
  26.     public static void main(String[] args) {
  27.         int referenceScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
  28.         int ranks[][] = new int[referenceScore.length][];
  29.         int totals[] = new int[referenceScore.length]; // total score for each team
  30.         int teamRanks[] = new int[referenceScore.length];
  31.         for (int row = 0; row < ranks.length; row++) {
  32.             ranks[row] = new int[referenceScore[row].length];
  33.             totals[row] = 0;
  34.             for (int col = 0; col < ranks[row].length; col++) {
  35.                 ranks[row][col] = getRank(referenceScore, row, col);
  36.                 totals[row] += referenceScore[row][col];
  37.             }
  38.         }
  39.         for (int team = 0; team < teamRanks.length; team++) {
  40.             teamRanks[team] = getTeamRank(totals, team);
  41.         }
  42.         System.out.println("          P1     P2     P3     P4     P5     P6   Total Rank");
  43.         for (int row = 0; row < ranks.length; row++) {
  44.             System.out.print("Team " + (row + 1) + " ");
  45.             for (int col = 0; col < ranks[row].length; col++) {
  46.                 System.out.printf("%2d(%2d) ", referenceScore[row][col], ranks[row][col]);
  47.             }
  48.             System.out.println(" " + totals[row] + "  " + teamRanks[row]);
  49.         }
  50.     }
  51. }

上述代码运行后产生以下输出：

  1.           P1     P2     P3     P4     P5     P6   Total Rank
  2. Team 1 39(11) 40( 8) 17(17) 35(13) 42( 1)  6(18)   179   3
  3. Team 2 40( 8) 41( 6) 27(15) 41( 6) 42( 1) 36(12)   227   1
  4. 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.

  1. public class RankScores {
  2.     private static int getRank(int[][] scores, int rowIndex, int columnIndex) {
  3.         int count = 0;
  4.         int score = scores[rowIndex][columnIndex];
  5.         for (int row = 0; row &lt; scores.length; row++) {
  6.             for (int col = 0; col &lt; scores[row].length; col++) {
  7.                 if (scores[row][col] &gt; score) {
  8.                     count++;
  9.                 }
  10.             }
  11.         }
  12.         return count + 1;
  13.     }
  15.     private static int getTeamRank(int[] scores, int index) {
  16.         int count = 0;
  17.         int score = scores[index];
  18.         for (int i = 0; i &lt; scores.length; i++) {
  19.             if (scores[i] &gt; score) {
  20.                 count++;
  21.             }
  22.         }
  23.         return count + 1;
  24.     }
  26.     public static void main(String[] args) {
  27.         int referenceScore[][]={{39,40,17,35,42,6},{40,41,27,41,42,36},{42,40,26,42,42,35}};
  28.         int ranks[][] = new int[referenceScore.length][];
  29.         int totals[] = new int[referenceScore.length]; // total score for each team
  30.         int teamRanks[] = new int[referenceScore.length];
  31.         for (int row = 0; row &lt; ranks.length; row++) {
  32.             ranks[row] = new int[referenceScore[row].length];
  33.             totals[row] = 0;
  34.             for (int col = 0; col &lt; ranks[row].length; col++) {
  35.                 ranks[row][col] = getRank(referenceScore, row, col);
  36.                 totals[row] += referenceScore[row][col];
  37.             }
  38.         }
  39.         for (int team = 0; team &lt; teamRanks.length; team++) {
  40.             teamRanks[team] = getTeamRank(totals, team);
  41.         }
  42.         System.out.println(&quot;          P1     P2     P3     P4     P5     P6   Total Rank&quot;);
  43.         for (int row = 0; row &lt; ranks.length; row++) {
  44.             System.out.print(&quot;Team &quot; + (row + 1) + &quot; &quot;);
  45.             for (int col = 0; col &lt; ranks[row].length; col++) {
  46.                 System.out.printf(&quot;%2d(%2d) &quot;, referenceScore[row][col], ranks[row][col]);
  47.             }
  48.             System.out.println(&quot; &quot; + totals[row] + &quot;  &quot; + teamRanks[row]);
  49.         }
  50.     }
  51. }

Running the above code produces the following output.

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