On the chapter 1, I guess the section "Answers to review questions" gave wrong for the questions 14 and 16.
For the question 14, it says the right options would be A, B, C and E.
But C doesn't work, once "-cp" has the short form "-c" (--create-file) and would provide also a "-p" that is an invalid argument for the "jar" command.
Regarding 16, it gives me a scenario where I have a file /my/directory/named/A/Bird.java, where my pwd would be /my/directory, and asks me possible package names in case I decided to compile that Bird.java file from the pwd.
Well, actually, with any of options 2(B), 4(D), 6(F) works fine, no compilation fail is raised when invoked;
$ (pwd /my/directory) javac named/A/Bird.java
But the "Answers to review questions" tells that for that question, the right option to be taken would be the 4(D).
