I believe "string" needs to be capitalized. So...

String firstName = "Derrick";

It's one of the weird exceptions in Java.

No, it's not weird. Java has 8 primitive data types.

  1. byte
  2. short
  3. int
  4. long
  5. float
  6. double
  7. boolean
  8. char

they are all in lower-capped.

though it's used very frequently, String isn't one of the primitive data type, String is a built-in class, and the code convention in Java is that class name begins with its first letter capitalized.

Welcome to Treehouse!

I wrote a little bit about the Cannot Find Symbol error on this post. You might take a look for your own future knowledge and Java errors.

Hello, java is very weird about its character types. As the comment suggests just capitalize String. Should do the ticket.

Let me know if this helps.
