Reverse String in java (Three ways to reverse string)

There are three ways to reverse the string :

1) Using For Loop

2) Using Recursion

3) Using StringBuilder

Reverse string Using For loop :

        

public class ReverseString{

        public static void main(String[] args) {

                String origional = "Programming";

                String reverse = "";

                for (int i = origional.length() - 1; i >= 0; i--) {

                reverse = reverse + origional.charAt(i);

        }

        System.out.println("Reverse String is : " + reverse);

        }

}

Output: 

        Reverse String is : gnimmargorP

Reverse string using Recursion: 

public class recursion1 {

        public static void main(String[] args) {

                recursion1 rsr = new recursion1();

                String Origional = "Programming";

                String reverse = rsr.recursion(Origional);

                System.out.println("Reverse string is:" + reverse);

        }

        public String recursion(String orig) {

                if (orig.length() == 1)

                        return orig;

                else

                        return orig.charAt(orig.length() - 1) + recursion(orig.substring(0, orig.length() - 1));

        }

}

Output: 

        Reverse String is : gnimmargorP

Reverse string using String Builder: 

public class reversemethod {

        public static void main(String[] args) {

                String Java = "Programming";

                StringBuilder sb = new StringBuilder(Java);

                System.out.println("Reverse string is: " + sb.reverse());

        }

}

Output: 

        Reverse String is : gnimmargorP
