java - 查找数组中最低值的索引号

Question

我必须返回 12 个数字数组中最低值的索引号。每次运行它时，我都会得到 12 作为结果。这是我的代码:

minRain = leastRain(months);

public static int leastRain (double[] mon4){
    int lowest = (int) mon4[0];

    for (int index=1; index<mon4.length; index++){
        if (mon4[index]<lowest)
            lowest = index;
    }
    return lowest;  
}

System.out.println("The month with the lowest amount of rain is: " + (minRain + 1));

Answer 1

您犯了一个愚蠢的错误 - 您将索引分配给变量而不是数组值。这样做:

public static int leastRain (double[] mon4){
    int lowest = 0;

    for (int index=1; index<mon4.length; index++){
        if (mon4[index]<mon4[lowest])
            lowest = index;
    }
    return lowest;  
}
