Reverse the number using command line argument.





How   to  reverse  the number   you  enter   and  find sum of this number .  Here   is  simple
 java code  for  beginners  to  reverse   the  number .
In  this   program  we   pass argument   through   command  you want   to reverse  then
using modulus  operator  we can   reverse this number . Each time  number divided by 10 .
Here  r  is remainder of n.

 

public class ReverseNumber {

public static void main(String args[]) {

int n=0;  

String s=args[0];
 
      n=Integer.parseInt(s); 

              System.out.println("entered num is: "+n);
                 
                 int r,sum=0,rev=0;
     
             while(n>0) {

                    r=n%10; 

                        n=n/10; 

                     rev=(rev*10)+r; 
               
                        sum+=r;

                 }

 
                System.out.println("sum of digits is: "+sum); 


             System.out.println("reverse of the num is: "+rev);

         } 


}


When  we   run this  code  using  argument   output will be .

entered num is: 2345
sum of digits is: 14

reverse of the num is: 5432
