Prime or Not

Java Program to check whether the number entered by user is Prime or Not.



package loops;
import java.util.Scanner;

public class Prime

{

public static void main(String[] args)
{
                Scanner input=new Scanner(System.in);
                System.out.println("Enter a number:");
int n=input.nextInt();
String prime="Yes, a prime number";
        for(int i=2;i*i<=n;i++)
       {
            if(n%i==0)
               {
                    prime="No, not a prime number"; 
                   break;
               }
       }
       if(n<2) 
                  prime="No, not a prime number";

        System.out.println(prime);

}


}
