We are still writing Chess960.java to generate random chess boards and record chess games with a mix of for each loops, while loops, static arrays and ArrayLists as well a 1D and 2D arrays! Version 1 will generate one board using the Random class and String. Version 2 will add an ArrayList of String to Randomly generate all 960 combinations. Then, Version 3 will use String  to play a game!
We finished Chess960V1 and started Chess960V2 this week. V2 uses an ArrayList to keep track of all the boards generated so far to avoid repetition. So that's a 2D data structure: an ArrayList with 960 String!
After all that, I think we'll go back to GridWorld Part IV. We'll also do some chapters on recursion, static classes and, finally, searching and sorting. Don't forget, we covered chapters 1-5 thoroughly before even starting GridWorld Parts I-III.
I think we'll continue Take Home Tuesdays from now until AP Week! We are now ready for Take Home #5 as we are good at loops and arrays.
Here's our ScreenCasts and Code for this last week:
