IMPORTANT: While you are in the lab, login in to a lab desktop, bring up chrome and visit this attendance app This will register your attendance in the lab. Make sure you have, at some point during the lab, logged in directly on a lab system (using the lab keyboard, monitor and mouse, no ssh!!).

Lab this week is help with the current assignment. Please show your work to the TAs!! Some tips for A2...

• Do not use instanceof/isInstance anywhere unless you absolutely have to.
• Have great separation of classes into M/V/C.
• Make great use of design patterns to simplify your code. I see at least places for Factory, Strategy, and Command, are there more? Don't use it if it doesnt make the code better, but definitely do if it does.
• Sometimes a good naming convention can replace a lot of code.
