It reads the first character in the strings as index zero, the second character as index one, and so on. When working on a program, if you want the character present on index two, you can get it simply by using the following statement:
Systme.out.println(a.charAt(2));
You print it in the output so that you will see that character. You might be wondering why would we need a single character from a string, but the charAt method is often used. In the next section, we will look at a program that can completely reverse the string.
For now, we will just go through an overview of the methods. We saw how to get a character that is present at a...
