This week we really will have that Java quiz!  We did some review last week, and will review again on Monday, so quiz on Tuesday.

If you had not noticed, many lessons give you the final code.  A good coder can read code well, and use this properly.  Blindly copying and pasting won't work.  For this quiz, this code is the basis:


In addition, here are some terms to know:

Monday review these files.  Which lines, concepts do you NOT understand?  Also, can you write an array, ArrayList, while loop, for loop?

  • Class vs object vs Java file
  • Intent
  • activity
  • view
  • xml java  (SQL is coming up!)
  • attribute
  • event
  • method
  • implicit intent
  • explicit intent
  • this
  • android:label for activity
  • eventListener
  • OnClickListener
  • Interface
  • implements
  • xml id attribute
And of course, arrays, ArrayLists, while loops and for loops

Then, we move on to developing our apps with ArrayLists, loops, then ListViews and ArrayAdapters!

I like this page a lot, which shows a Java activity file and it's associated XML view page:
