Here is my solution to

Write a program to check whether a number is prime in Java

class Prime
{
 public static void main(String arg[])
 {
 int n,c=0;
 n=Integer.parseInt(arg[0]);
 for(int i=2;i<=n/2;i++)
 {
 if(n%i==0)
 c++;
 }
 if(c>0)
    System.out.println(n+" Is not prime no.");
 else
 System.out.println(n+" Is prime no.");	
 }
}

Output:
