1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

public class ReverseString { //Using For Loop public static void usingLoop(String str){ String reverse = ""; for(int i=str.length()-1;i>=0;i--){ reverse+= str.charAt(i); } System.out.println("REVERSE USING LOOP : "+reverse); } //Using String Buffer public static void usingStringBuffer(String str){ StringBuffer sb = new StringBuffer(str); sb.reverse(); System.out.println("REVERSE USING STRING BUFFER : "+sb); } //Using Recursive Method public static String usingRecursion(String str){ if(str == null || str.length() <= 1 ){ return str; } return usingRecursion(str.substring(1))+str.charAt(0); } public static void main(String[] args) { ReverseString.usingLoop("pushkar"); ReverseString.usingStringBuffer("pushkar"); System.out.println("USING RECURSIVE METHOD "+ReverseString.usingRecursion("pushkar")); } }

Output : 

REVERSE USING LOOP : rakhsup

REVERSE USING STRING BUFFER : rakhsup

USING RECURSIVE METHOD : rakhsup
