• Set up your course directory and protect it
• Play with Netbeans, our IDE for this semester
• Compile and run a Java program from the command line
• Play with the BlobWorldFun project we saw in class this week
• Ensure access to the tester and world libraries we’ll be using this semester
• Ensure you can successfully submit your assignment
  
  

Note that these instructions are less detailed than they were in 101/102. That’s meant as a compliment , but don’t hesitate to ask me or one of the coaches any questions!

1. Create and protect a cs203 course directory under your home directory
2. Show Marc or one of the coaches your protected course directory before proceeding

1. Copy the BlobWorldFun project from ~cs203/labs/ to your course directory
2. Launch Netbeans, and open your copy of the BlobWorldFun project
3. Mouse over the button bar and explore until you find the “Build Project”, “Clean and Build Project”, and “Run Project” buttons
4. Clean and build your project
5. Run BlobWorldFun several times, playing with arrow keys and mouse clicks to control the blob, and color abbreviation keys to change the color of the blob
6. Intentionally end the game by guiding the blob into the black hole, as well as each of the four walls
7. Read through the code, play with the code, see what you can change about BlobWorldFun

How to compile and run a Java program with tester library from the command line.

1. Open the terminal window.

2. cd into your course directory

3. Copy the Shapes project to your course directory:
cp -r ~cs203/labs/Shapes ./

4. cd into your newly copied Shapes directory:
cd Shapes

5. To compile your program type into command line:
javac -cp .:/home/cs203/jars/tester.jar *.java

6. To run your program type into command line:
java -cp .:/home/cs203/jars/tester.jar tester.Main

If all goes well, you should see as the last few lines of output:

Ran 18 tests.
All tests passed.
Issued 5 warnings of inexact comparison.
