排名数组Java
我正在尝试在我的作业中对数组进行排名，但是我不知道该怎么做。有人能帮我吗？先感谢您
我添加了完整作业说明的图像。 这是我的代码：
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 < 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;
}
// Print out the
System.out.println("\tP1\tP2\tP3\tP4\tP5\tP6\tTotal\tRank");
// Prints out the results and the rank for each team
for(int teamNb = 0; teamNb<3; teamNb++){
System.out.print("Team"+(teamNb+1));
for(int p=0; p<6; p++){
total = total + finalScore[teamNb][p];
System.out.print("\t" + finalScore[teamNb][p]+"("+ scoreAmongOthers[teamNb][p]+") ");
}
System.out.print("\t"+ total);
total = 0;
System.out.println();
}
}
}

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回答来源：Stack Overflow
