reverse the position of integer digits?

Question

i have to reverse the position of integer like this

input = 12345

output = 54321

i made this but it gives wrong output e.g 5432

#include         


        

Answer 1

public class TestDS {

public static void main(String[] args) {

    System.out.println(recursiveReverse(234));
           System.out.println(recursiveReverse(234 ,0));



}



public static int reverse(int number){

    int reversedNumber = 0;
    int temp = 0;


    while(number > 0){

        //use modulus operator to strip off the last digit
        temp = number%10;

        //create the reversed number
        reversedNumber = reversedNumber * 10 + temp;
        number = number/10;

    }



    return reversedNumber;

}



private static int reversenumber =0;
public static int recursiveReverse(int number){

    if(number <= 0){

        return reversenumber;
    }

    reversenumber = reversenumber*10+(number%10);
    number =number/10;

    return recursiveReverse(number);

}

public static int recursiveReverse(int number , int reversenumber){

    if(number <= 0){

        return reversenumber;
    }

    reversenumber = reversenumber*10+(number%10);
    number =number/10;

    return recursiveReverse(number,reversenumber);

}

}
