Hi friend,

Code to help in solving the problem :

import java.io.*;

class PrimeNumber {
public static void main(String[] args) throws Exception{
int i;
BufferedReader bf = new BufferedReader(
new InputStreamReader(System.in));
System.out.println("Enter number:");
int num = Integer.parseInt(bf.readLine());
System.out.println("Prime number: ");
for (i=1; i < num; i++ ){
int j;
for (j=2; j<i; j++){
int n = i%j;
if (n==0){
break;
}
}
if(i == j){
System.out.print(" "+i);
}
}
}
}

Thanks
