如何获取数组中最大值的索引？

Question

我有两个数组

String[] city;
int[] temp;

它们的长度都是4。City保存每个城市的名称，temp保存每个城市的平均温度。温度中的温度与城市中的城市顺序相同。所以我的问题是，我怎样才能得到temp中最大int的索引？我想打印出来

"The city with the highest average temperature is " + city[index] + 
" with an average temperature of " + temp[max];

如果不想使用其他类，可以执行以下操作。您需要存储max和max所在位置的索引，以便还可以打印城市

String[] city = getCities ();  // assuming this code is done
int[] temp = getTemparatures ();
int max = Integer.MIN_VALUE;
int index = -1;

for(int i = 0; i < temp.length; i ++){
    if(max < temp[i]){
        max = temp[i];
        index = i;
    }
}

System.out.println ("The city with the highest average temperature is " + city[index] + 
" with an average temperature of " + temp[index]);
