Hi Friend,
Try the following code:
import java.util.*; class PrimeNumbers{ public static void main (String args[]){ System.out.println("Enter the start range:"); Scanner input=new Scanner(System.in); int num1=input.nextInt(); System.out.println("Enter the end range:"); int num2=input.nextInt(); String primeNo = ""; int counter = 0; System.out.println("Prime Numbers between "+num1+" and "+num2+" are:" ); for (int i = 5; i < 20; i++){ { int j; for (j = 2; j < i; j++) { if (i % j == 0) { break; } } if (i == j) { primeNo += i + " ";
} } } System.out.println(primeNo); } } Thanks
