print it's
WAP to input a 4 4 digit number and
reverse in java
​

Answer 1

I have used the reverse() function

import java.util.Scanner;

public class NumberReverser {

   int reverse = 0;

   public static void main(String [] args){

       Scanner sc = new Scanner(System.in);

       System.out.print("Enter a number: ");

       StringBuilder number = new StringBuilder(sc.next());

       System.out.print("The reversed number is ");

       System.out.print(number.reverse());

   }

}

Output:

Enter a number: 123456789

The reversed number is 987654321
