1. package basics.java.com; 
2. public class MyPrimeNumCheck 
3. {
4.  public boolean isPrimeNumber(int number)
5. { 
6. for(int i=2; i<=number/2; i++)
7. {
8.  if(number % i == 0)
9. {
10.  return false; 
11. }
12.  } 
13. return true; 
14. } 
15. public static void main(String a[])
16. { 
17. MyPrimeNumCheck mpc = new MyPrimeNumCheck();
18. System.out.println("Is17primenumber?"+mpc.isPrimeNumber(17));
19. System.out.println("Is 19 prime number? "+mpc.isPrimeNumber(19));
20. System.out.println("Is 15 prime number? "+mpc.isPrimeNumber(15));
21.  }
