Use of variables in methods like charAt()

[Grisbas]

Hi.
I'm aware of creating methods like charAt() is one.

Random

String s = "Random text";

System.out.println(s.charAt(2));

What I'm confused about how it is possible for charAt() to use the string "s"? What's the deal? Does it parse the string to the class? There's probably an easy answer to this, but I've yet to see how it works, which is why I'm asking for help. A link to a tutorial answering my question would be awesome.

Thanks in advance.

The string s is an object of type String. So like any other object, there are methods which are specific to the class which operate on the object. In this case, String is backed by a char[] array. So when you pass an argument to charAt() it returns the character at that location in the array.
