Java 如何从数组中读取两个值并确定哪个值更大？

我是一个编程新手，有人给了我一个挑战，我被卡住了

我们有一个数组（整数[][]匹配），其中包含多个数组，每个数组都有分数（整数[]匹配结果）。如果匹配结果[0]大于匹配结果[1]，则视为获胜。如果匹配项[0]小于匹配项[1]，则其将被视为丢失。如果他们相等，那就是平局。我需要从比赛总数中确定胜负和平局的百分比。这是我最初得到的：

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;

    for (int i = 0; i<amountOfMatches; i++){
        Integer nrMatch = i;
        Integer[] match_result;

    }

    return "Wins: " + percentWin + " Losses: " + percentLoss + " Ties: " + percentTie;
}

整数[][]匹配={{2,2}、{3,2}、{4,1}、{1,3}、{3,5}、{1,1}、{1,0}、{0,0}、{1,2}、{0,2}、{0,3}、{1,0}；
System.out.println（结果（匹配））；
}
公共静态字符串结果（整数[][]匹配）{
整数百分比=0；
整数百分比损失=0；
整数百分比=0；
整数amountOfMatches=13；
对于（int i=0；i
match_result=matches[i]；
？谢谢immibis！刚刚更新了代码。知道为什么percentWin、percentLoss和percentTie返回为0吗？整数数学。
int percentWin=（int）（100*（（双）赢/amountOfMatches））
@Joey说有100场比赛，其中70场是输的。70/100==0.0*100==0。非常感谢Elliot和immibis。我将检查所有这些。代码现在运行得很好。
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;
}
