Question

int diff = gamesA[0] - gamesB[0];
    for(int i = 0; i < gamesA.length; i++)
    {
        int y = Math.abs(gamesA[i] - gamesB[i]);
        if(y > diff)
        diff = y;
    }
    System.out.println("In quarter finals, largest deficit of schoolB was " 
+ diff + " in the" +_____+ "game.");

我正在尝试打印出赤字最大的数组中的索引。不是值，而是它所在的索引。一切都有帮助。“ ____”是需要放置所需代码的地方。

Answer 1

只需声明变量即可在循环外存储索引

Answer 2

通过以下方式：

int diff = gamesA[0] - gamesB[0];
int i; // declare it outside the loop to make it available after loop ends.
    for(i = 0; i < gamesA.length; i++)
    {
        int y = Math.abs(gamesA[i] - gamesB[i]);
        if(y > diff)
        diff = y;
    }
    System.out.println("In quarter finals, largest deficit of schoolB was " 
+ diff + " in the" +(i+1)+ "game.");
//i+1 for indexing from 1 onward .. or use just i for indexing 0 onward.

到目前为止，其他答案将始终显示最后一个位置。试试这个：-

int diff = gamesA[0] - gamesB[0];
int pos = 0;
for (int i = 0; i < gamesA.length; i++) {
    int y = Math.abs(gamesA[i] - gamesB[i]);
    if (y > diff) {
        diff = y;
        pos = i;
    }
}
System.out.println("In quarter finals, largest deficit of schoolB was "
        + diff + " in the" + pos + "game.");
