Hi Friend,

Try this:

import java.util.*;

public class ReverseNumber {
    public static void main(String[] args) {
        try {
            Scanner input = new Scanner(System.in);
            System.out.print("Enter number: ");
            int num = input.nextInt();
            int n = num;
            int reversedNumber = 0;
            for (int i = 0; i <= num; i++) {
                int r = num % 10;
                num = num / 10;
                reversedNumber = reversedNumber * 10 + r;
                i = 0;
            }
            System.out.print("After reversing, number be: "+reversedNumber);
        }
             catch (Exception e) {
            System.out.println(e);
        }
    }
}

Thanks
