5 {
6 Scanner sc= new Scanner (System.in);
7 int n,i,count=0;
8 System.out.print("Enter a number: ");
9 n=sc.nextInt();
10 for (i=1; i<=n;i++)
11 {
12 if(n%i==0)
13 {
14 count++;
15 }
16 }
17 if(count==2)
18 System.out.println(n+" is Prime Number");
19 else
20 System.out.println(n+" is not Prime Number");
21 }
22 }
You will get the following output:
