Write a program in java to accept two numbers and check whether they are twin prime or not.

Twin Primes

A pair of prime numbers that differ by 2 (successive odd numbers that are both Prime numbers). 

Examples: (3,5), (5,7), (11,13), ...

import java.util.*;

class twin_prime
{
    public static void main(String args[])
    {
        int n1,n2,i,c1=0,c2=0,d;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter two numbers");
       
        n1=sc.nextInt();
        n2=sc.nextInt();
       
        for(i=1;i<=n1;i++)
        {
            if(n1%i==0)
            c1++;
        }
         for(i=1;i<=n2;i++)
        {
            if(n2%i==0)
            c2++;
        }
        d=Math.abs(n1-n2);
      
        if(d==2 && c1==2 && c2==2)
        System.out.println("Twin prime");
        else
        System.out.println("Not Twin prime");
    }
}
Output:
Enter Two numbers:
5
7
Twin prime
