Reversing a string's logic

In this section, let's see how we can print a string in reverse. This is one of the questions that was asked in the Yahoo interview. Let's create a reversedemo class for our example.

We have a string called Rahul, and we want the output to be luhaR. There is one more concept that we need to be aware of: a palindrome. If you type in a string, such as madam, and we reverse the string, it would just give madam as the output. Such types of strings are called palindromes. One such instance of a palindrome is shown in the following code:

package demopack;public class reversedemo {            public static void main(String[] args) {        String s = "madam";        String t= "";        for(int i=s.length()-1; i>=0; i--)        {            t= t+ s.charAt(i);        } System.out.println(t); ...
