Program to reverse a number and find its sum using java

PROGRAM:

                                                                     
                                                                     
                                                                     
                                             
package reverse;
import java.io.*;

 public class reverse {
 public static void main(String[] args)throws IOException {
        BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter a number ");
        int num=Integer.parseInt(in.readLine());
        int n=num;
        int temp=0,rem=0,sum=0;
       while(num>0)
        {
            temp=num%10;
            rem=rem*10+temp;
            num=num/10;
            sum=sum+temp;
        }
        System.out.println(rem+" is a reverse of "+n);
        System.out.println(sum+" is the sum of digit "+n);
        // TODO code application logic here
    }

}

OUTPUT:
