It certainly is covered. There's a whole page dedicated to it (across pages 135-136 in Chapter 6 "RequestDispatcher & Wrappers"). The 10 mentioned by Christophe, above, form the complete set.
As you'll have noticed, the 10 quickly reduce to 5 for learning purposes, by exchanging the "include" for "forward" in the stem. The names are also all lower case, using an underscore where the
Java method name would capitalise. Just a couple of hints.
