Question

    public class Survey
{
    public static void main(String[] args)
    {
        int[] survey = {1,2,6,4,8,5,9,7,8,10,1,6,3,8,6,10,3,8,2,7,6,5,7,6,8,6,7,5,6,6,5,6,7,5,6,4,8,6,8,10};
        int length = survey.length;
        int undivided = 0, avg;
        for(int loop = length -1; loop>=0; loop--)
        {
            int add = survey[loop];
            System.out.println(add);
            undivided = add + undivided;        
        }
        System.out.println(undivided);
        avg = (undivided/length);
        System.out.println("The average score for the cafeteria was:" + avg);
        System.out.println(countFrequencies(survey[3]));
    }

    public static void countFrequencies(int input[]) { 
        int n = input.length;
        for (int i = 0; i < n; i++) {
            input[i]--;
        }

        for (int i = 0; i < n; i++) {
            input[input[i] % n] += n;
        }

        for (int i = 0; i < n; i++) {
            System.out.println((i + 1) + " " + input[i] / n);
            input[i] = input[i] % n + 1;
        }
    }
}

如何输入频率方法......它不起作用。我不知道我还能尝试什么，但当我尝试输入任何内容时，它似乎有点问题。它不会正常运行。

错误：

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
The method countFrequencies(int[]) in the type Survey is not applicable for the arguments (int)
    at Survey.main(Survey.java:18)

Answer 1

survey是int[]
survey[3]是int
countFrequencies()需要int[]参数，但获得survey[3] int

如何输入采用数组的方法？
