Javaв„ў EE 5 Tutorial, The (3rd Edition)

You might note an inconsistency in the coding style here. I used bool rather than Boolean. It would be better to be consistent, but in this case I fell short of that goal. You ll probably find other examples as you go through the book. They re part of my learning process, and I ll point them out when I notice them.

Also notice the commented-out code here. It s the result of an attempt to write a test that I later decided was a dead end. I should have had the courage to delete the code, but I must have decided to keep it in case I needed it. As far as I can tell from here, I never needed it. You can draw the obvious lesson from that and delete such things. Trust your code manager to keep a copy, or print the code and keep a big stack of paper in your bottom desk drawer .
