数组：从键盘上输入10个数，合法值为1、2或3，不是这三个数则为非法数字，试编辑统计每个整数和非法数字的个数

import java.util.Scanner;

public class Demo6 {

public static void main(String[] args) {

// TODO Auto-generated method stub

int[] nums = new int[10];

int[] count = new int[4];

System.out.println("请输入10个数：");

Scanner input = new Scanner(System.in);

for(int i=1;i<nums.length;i++){

nums[i] = input.nextInt();

switch(nums[i]){

case 1:

count[0]++;

break;

case 2:

count[1]++;

break;

case 3:

count[2]++;

break;

case 4:

case 5:

case 6:

case 7:

case 8:

case 9:

case 0:

count[3]++;

break;

}

}

System.out.println("数字1的个数为："+count[0]);

System.out.println("数字2的个数为："+count[1]);

System.out.println("数字3的个数为："+count[2]);

System.out.println("非法数字的个数为："+count[3]);

}
