Java Program to find the Prime numbers using values from Terminal as input through (String [] args)

class PrimeNo

{

    public static void main(String[] args) /*String []args will take

input from the terminal(cmd command line) directly */

    {

        int n;

        for(int i=0;i<args.length;i++) /* using length function to get the total

length of the one dimensional array*/

        {

            int j=2;

            n=Integer.parseInt(args[i]); /*using parseInt function

from Integer class to convert the

numbers (which are in String) into the integer*/

            for(;j<=Math.sqrt(n);j++)

            {

                if(n%j==0)

                    break;

            }

            if(j>Math.sqrt(n))

                System.out.println(n+" = Prime Number");

            else

                System.out.println(n+" = Not Prime Number");

        }
