4 //验证质数

6 public static void main(String[] args){
7 Scanner scan = new Scanner(System.in);
8
9 int num = scan.nextInt();
10 int counter = 0;
11
12 //算质数可能
13 for(int i=2;i<num;i++){
14 if(num%i == 0){
15 counter++;
16 }
17 }
18
19 //判断
20 if(counter>0){
21 System.out.println(\”输入值\\t\”+num+\”\\t不是质数\”);
22 }else{
23 System.out.println(\”输入值\\t\”+num+\”\\t是质数\”);
24 }
25 scan.close();
