For this project I'm restricted to Java 2.
I'd like to find something that's a cross between a HashMap and a FIFO
buffer.  I want to store objects by name, but when it gets to a certain
size I want to automatically drop the oldest one in the queue.

I am trying to do exercise 17 on page 546 of Bruce Eckel's Thinking In
Java (4th edition):
"Write a program that reads a Java source-code file (you provide the
file name on the command line) and displays all the comments."

Is this the best we to conditionally do something if str is NOT equal to
one, two, three, or four, AND mystr is NOT equal to X?  I can't seem to
find anything like a str.unequal.  I want the if block to execute if str
equals "seven" and mystr equals "Y"

I need to generate all possible combinations of 16 bit long trinary.
e.g.
0000000000000000
0000000000000001
