Three Different Way of Reversing a String in Java

 As salamo alaikum wa rahmatullah

package examples;

import java.util.Scanner;

public class ReverseString {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc=new Scanner(System.in);

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

String str=sc.nextLine();

int len=str.length();

String rev="";

for(int j=len-1;j>=0;j--) {

rev=rev+str.charAt(j);

}

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

rev="";

char a[]=str.toCharArray();

int len1=a.length;

for(int k=len1-1;k>=0;k--)

{

rev=rev+a[k];

}

System.out.println("Again the reverse :- "+rev);

// Reverse string using StringBuffer class

StringBuffer sbf=new StringBuffer(str);

StringBuffer rev2=sbf.reverse();

System.out.println("Again the reverse :- "+rev2);

}

}
