Post-3

Review Modules 3 and 4 by reading them twice.
Complete all in-class exercises in the modules up through the end of Module 4.
Download DrawTool.java and FaceDrawing.java. Then compile and execute. You'll see that the code in FaceDrawing.java uses methods in DrawTool to draw a very simple (if creepy) face. For now, you can ignore the text-input and "enter" button. For this assignment, create your own, more elaborate drawing. It can be anything you like, and should make at least 15 different method invocations to methods in DrawTool. There will be points for originality, humor and drawing quality. You can do this part of Post-3 in steps:
- First, play around with the numbers in methods like drawOval so you get a sense of how it works.
- Then, sketch out your drawing on paper.
- After that, you build your picture piece-by-piece.
A smart thing to do: don't write up all your drawing's code in one shot. Instead, test out smaller parts as you proceed.
Download MakeSquares.java and add code to this program. The output needs to be exactly this:
```
******      ******      
******      ******      
******      ******      
******      ******      
      ******      ******
      ******      ******
      ******      ******
      ******      ******
******      ******      
******      ******      
******      ******      
******      ******      
      ******      ******
      ******      ******
      ******      ******
      ******      ******
```
Of course, we know you can write a bunch of System.out.println's. So, to make it a little more interesting:
- In your code, you may NOT call System.out.print or System.out.println. In fact, to print, all you are allowed to do is to call one of the three methods already provided: printSixStars, printSixSpaces, or newLine.
- You can create methods of your own making to help reduce redundancy, as you did with the "MOO" example in class.
- What is the total number of method invocations in your program? Can you write a program with the fewest possible method invocations, i.e., a program as compact as possible?
Read sections 1.4, 2.1, 2.2 and 2.3 of the textbook.
Do the self-check exercises 20, 23 and 27 on pages 50-52 of the textbook.
Don't forget your reflection exercise!

Submission: For this assignment, we'll use Blackboard for submission. Go to assignments and then to post-3.

Recommended, but not required:

Watch this video about new interfaces to computing.
Look up the term Augmented Reality. What does it mean? Then do a search on "Word Lens" to see what an augmented reality application looks like.
