java面试--（生成随机数，获取重复次数最多，并且数是最大的一个，打印出来）

import java.util.*;

public class MaxRandom {

    public static void main(String[] args){
        int[] num = new int[10];
        for(int i=0;i<10;i++){
            num[i]=getRandomNum();
            System.out.print(num[i]+" ");
        }
        System.out.println();
        FindMax(num);
    }

    public static int getRandomNum()
    {
        return ((int) (Math.random()*10));
    }

    public static void FindMax(int[] num){
        int maxCount = -1,maxValue = -1;
        int [] count = new int [11];

        Arrays.sort(num);
        System.out.println(Arrays.toString(num));

        for(int index =0;index<num.length&&num[index]>=0;index ++)
        {
            count[num[index]]++;
            if(count[num[index]]>maxCount || (count[num[index]]==maxCount && maxValue<num[index]) )
            {
                maxCount = count[num[index]];
                maxValue = num[index];
            }
        }
            System.out.println("The max count number is "+ maxValue+", the count is： "+maxCount);

    }

}

运行：

6 7 5 1 2 6 8 5 8 6
[1, 2, 5, 5, 6, 6, 6, 7, 8, 8]
The max count number is 6, the count is： 3
