Not getting key events? Here's the solution.

As you use a GUI, different components get the "focus." The element with the focus is the one that gets the key events. For example, if you have several buttons, hitting the Tab key will move focus from one button to another; then hitting Enter will "click" that button.

If the key listener for your Snake game isn't getting keystroke events, that probably means some other component (maybe your Play button) is getting those events. You have to tell your component, the one that you want to listen for key events, to requestFocus(). You may have to do this in more than one place, if there is a way for your component to lose the focus to some other component.

The next two evaluation forms are ready, due by next Wednesday.

• Evaluation form for 10 Drake's Equation

The next two evaluation forms are ready, due by next Wednesday.

• Evaluation form for 07 Balanced Ternary (the API, not the calculator)
• Evaluation form for 08 Balanced Ternary Calculator

Here is the next evaluation form, due by this Friday:

• Evaluation form for 06 Word Counter

Here are the older ones, due this Wednesday:

• Evaluation form for 03 Name That Number!

• Evaluation form for 05 Playfair Cipher

First MCIT talk of the year!

Rebecca Mercuri will talk on How Computers Will Steal the 2008 Election!
Tuesday, October 28, 7 p.m.
Wu & Chen Auditorium, Levine Hall

If you care about voting (whether in this country or some other), this is a talk you should attend!

The previously defined constructor took no parameters:

public WordCounter() {
    // Call loadFile to read in a list of stop words
    // Call loadFile to read in the text containing words to be counted
    // Either save these lists somewhere OR call a method to count things
}

The new constructor takes these two parameters, in this order:

public WordCounter(ArrayList<String> stopWords, ArrayList<String> text) {
    // Either save these lists somewhere OR call a method to count things
}

This second constructor allows you to test everything without having to read in files. This is a big help, because your JUnit tests can be self-contained; you don't need to keep the JUnit tests in perfect agreement with the test files.

Partner Evaluation Forms. I will be requiring you to evaluate your partner for each assignment, starting with the previous three assignments. Whatever you put in these forms will be completely confidential; no one but me will know what is in them.

• Evaluation form for 03 Name That Number!
• Evaluation form for 04 Random Activity
• Evaluation form for 05 Playfair Cipher

I will use this data to aid me in assigning partners. In addition, if you have very high or very low partnership scores, this may affect your final grade.

Turn these three evaluations in by Wednesday, October 29. Each completed evaluation you turn in by that date will count as 10 points toward your total programming score. Evaluations turned in late will be worth 5 points each.

Please keep your calendars free for:

• Wednesday, October 22, 6 p.m.
  Monday, October 20 (couldn't get a room for Monday) -- Probable pizza/hoagie party
  
  We will have the usual Monday 4:30 help session in DRL 3C6.
  
  
• Tuesday, October 28 -- First MCIT lecture -- Computers and electronic voting machines

Things to check in your LunarLander program:

• Can you play more than one game?
• Can you play more than two games?
• When you ask the user whether s/he wants to play again,
  • Do you accept (and do the correct thing with) any input that begins with 'y', 'Y', 'n', or 'N'?
  • If the user types something else, do you keep asking until you get one of the above?
• Do you let the user burn more fuel than you actually have?
• If the user asks to burn more fuel than you have, do you burn all and only the amount that remains?
• When you land safely, is the altitude reported as zero?

All these things are in the assignment. Please re-read the assignment carefully before you turn in your program.
