The first test for this course will take place in class on Friday, February 17. It will cover Chapters 1, 2, and 3 from the textbook and Labs 1 through 5. We did not cover everything from Chapter 1 in detail; you are only responsible for what we covered in class. A lot of graphics commands were used in the labs, but you are only responsible for knowing how to use the few that are listed below.
The test will include some short answer questions, similar to those that were given on quizzes. There might be one or two longer essay questions. There will certainly be some programming problems. Some of these will ask you to write short segments. There will probably be one question that asks you to write a complete program, so you should be sure that you know the format for that, including the "public static void main(String args)". You might be asked to read some code and say what it does. You should make sure that you have memorized the syntax of all the different types of statements and expressions that we have covered.
Here are some of the terms and ideas that you should be familiar with:
