In This Program We Learn to Print All Prime Numbers in an Interval

Example: Code Program

import java.util.*;

public class PrimeNum {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

int l, h, j, f = -1;

System.out.print("Enter Starting Point:");

l = sc.nextInt();

System.out.print("Enter Ending Point:");

h = sc.nextInt();

System.out.print("Prime Number Between "+l+" and "+h+ " are\n" );

while(l<h) {

f = -1;

j = 2;

while(j < l/2) {

if(l%j == 0)

f = f+1;

j = j+1;

}

if(f == -1)

System.out.print(l+" ");

l = l+1;

}

}

}
