Hi Friend,

Try this:

import java.util.*;

public class ReverseNumber {
    public static int reverse(int num){
        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;
            }
            return reversedNumber;
    }
    public static void main(String[] args) {
            Scanner input = new Scanner(System.in);
            System.out.print("Enter number: ");
            int num = input.nextInt();
            System.out.println("Reversed Number: "+reverse(num));
    }
}

Thanks
