kako Revunesite niz Java koristeći rekurziju

U ovom primjeru programa obrnut ćemo niz koji je unio korisnik.

Napravit ćemo funkciju za okretanje niza. Later pozivat ćemo ga rekurzivno dok se svi znakovi ne obrnu.

Napiši a Java Programirajte za Reverse String

package com.guru99;
 
public class ReverseString {
 
	public static void main(String[] args) {
 
 
		String myStr = "Guru99";
 
 
		//create Method and pass and input parameter string 
		String reversed = reverseString(myStr);
		System.out.println("The reversed string is: " + reversed);
		
	}
 
 
	//Method take string parameter and check string is empty or not
	public static String reverseString(String myStr)
	{
		if (myStr.isEmpty()){
		 System.out.println("String in now Empty");	
		 return myStr;
		}
		//Calling Function Recursively
		System.out.println("String to be passed in Recursive Function: "+myStr.substring(1));
		return reverseString(myStr.substring(1)) + myStr.charAt(0);
	}
 
}

Izlaz koda:

String to be passed in Recursive Function: uru99
String to be passed in Recursive Function: ru99
String to be passed in Recursive Function: u99
String to be passed in Recursive Function: 99
String to be passed in Recursive Function: 9
String to be passed in Recursive Function: 
String in now Empty
The reversed string is: 99uruG
