Reverse a string without using any in-built string functions?

Answer:

import java.io.*;
import java.util.*;
class ReverseString

{

public static void main(String args[])
{

String original, reverse = "";

Scanner in = new Scanner(System.in);


System.out.println("Enter a string to reverse");

original = in.nextLine();


int length = original.length();


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

reverse = reverse   original.charAt(i);


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

}

}
