我是编程的新手，我遇到了一个我遇到的挑战。
我们有一个数组（Integer [] []匹配），有几个数组，每个匹配得分（Integer [] match_result）。如果match_result [0]大于match_result [1]，则将其计为胜利。如果匹配[0]小于匹配[1]，则将其计为丢失。如果他们相等，那就是平局。我需要确定比赛总数中的胜负百分比。这是我最初给出的：
public class Main {
public static void main(String args[]){
Integer[][] matches = {{2,2},{3,2},{4,1},{1,3},{3,5},{1,1},{1,0},{0,0},{1,2},{0,2},{0,3},{3,3},{1,0}};
System.out.println(results(matches));
}
public static String results(Integer[][] matches){
Integer percentWin = 0;
Integer percentLoss = 0;
Integer percentTie = 0;
Integer amountOfMatches = 13;
Integer win=0; //added by me
Integer lost=0; //added by me
Integer tie=0; //added by me
for (int i = 0; i<amountOfMatches; i++){
Integer nrMatch = i;
Integer[] match_result;
//added by from here down
match_result = matches[i];//edited thanks to user:immibis
if (match_result[0]>match_result[1])
win++;
else if (match_result[0]<match_result[1])
lost++;
else
tie++;
percentWin= (win/amountOfMatches)*100;
percentLoss= (lost/amountOfMatches)*100;
percentTie= (tie/amountOfMatches)*100;
}
//it's not returning the percentages, any idea why???
return "Wins: " + percentWin + " Losses: " + percentLoss + " Ties: " + percentTie;
}
}
这就是我写的。我留下了一些我遇到问题的评论：
