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);
    }
}    

We would start by creating a string, called s, and an empty string, called t. We create this empty string to concatenate each element after the for loop to get...
