How can I write a code to output the same result as this cod

How can I write a code to output the same result as this code but using recursion in java.

public class Recursion{

public static void main(String[] args)
   {
       Scanner keyboard = new Scanner(System.in);
      
       System.out.println(\"Enter a String\");
       String input = keyboard.nextLine();
      
       int len = input.length();
       char[] tempCharArray = new char[len];
  
       for(int i = 0; i < len; i++)
       {
           tempCharArray[i] = input.charAt(i);
           System.out.println(tempCharArray[i]);
       }

}

}

Solution

Hi, Please find my recursive code.

Please let me know in case of any issue.

import java.util.Scanner;

public class Recursion{

   public static void recursion(char[] tempCharArray, int i, String input){

       // base case

       if(i == tempCharArray.length)

           return;

       tempCharArray[i] = input.charAt(i);

       System.out.println(tempCharArray[i]);

       recursion(tempCharArray, i+1, input);

   }

   public static void main(String[] args)

   {

       Scanner keyboard = new Scanner(System.in);

       System.out.println(\"Enter a String\");

       String input = keyboard.nextLine();

       int len = input.length();

       char[] tempCharArray = new char[len];

       // calling recursive function

       recursion(tempCharArray, 0, input);

   }

}
