Hi,

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

import java.util.*;
public class ReverseNumber {
    public static int reverse(int num){
    int n = num;
    int reversedNumber = 0;
        while(n>9){
         int r=n%10;
         n=n/10;
         num = num * 10 + r
        }
       return num;
    }

    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));   

    }
     }
