Java Command Based Crash Course Concept

[JesseK]

Tough to debug - the 'set' methods allow you to put breakpoints to figure out what code is causing change. This is particularly important in multi-threaded code. At the same time, I rarely actually put breakpoints in simple 'set' methods as a veteran.

Make the member variables immutable with the 'final' keyword and use the variables directly. Then it's fine from a pragmatic perspective. Grumpy people will argue about style, but whatever. I mean, it's not as bad as javascript, where anything can change anything, and you can pass a variable in where a functor should be and nothing stops you until it blows up 10 calls into the stack...
