R 4/10
    Java Graphics and Animation:
  • You may find this talk given to high school teachers helpful: HERE
  • Example code from the MACUL talk Circles
  • Another example: Timer0 Button control to output text
  • Another example: Timer1 Button control, randomly jumping rectangle
The due date on this is 4/15!!
Java code! Write an infinite loop that is controlled by a Java GUI. There is a long counter, the counter is incremented inside the loop. When the counter reaches values that are big enough so that you get a megatick every 5 - 10 seconds (formerly "multiples of one million") output a 'megatick' to the GUI. The counter should wrap-around to zero (not cause overflow). The GUI has a start button, a stop button (both of which turn turn on and off the Swing timer), the megatick is written to the GUI, not to the console. The code for the counter is inside the Swing timer actionPerformed() -- that is, only increment the counter (possibly multiple times) when the timer goes off.
Writing this with threads rather than with a Swing Timer is acceptable.
Looking for: writing to GUI, using Swing timer, Timer() controlled by buttons, infinite loop
T 4/8 Java code! This HOMEWORK is now JUST an EXTRA CREDIT ASSIGNMENT, due 4/17. Rewrite TenThreads.java so there are only two threads doing the work on an array. Demo on 10 X 10, and 1000 X 1000 arrays
T 4/1 Elementary DOM surgery
Write three images side-by-side on a page. Clicking a button causes them to rotate to the right. Use DOM 'surgery' to change the html on the fly.
R 3/27 Inclass test: open book/internet
up to, but not including regular expressions
T 3/25 Reverse engineering:
Consider this Javascript program written by ace coder Jan Wolter: Jan's flood-it
Observe how he uses a submit button (labelled "new game") to get parameters for his board (board size and colors)
Modify your inlab from 02/18/2014, #2, to make a slide show of four pictures (or start from scratch): using only a selection list of allowed delays, 1, 2, 3, 4 ms, and the Start button. The Start button is now a submit button that supplies the chosen delay amount.

R 3/20 Regular expressions Inlab: Given a string, e.g., "now is the time for all good men to come to the aid of the party", obtain an array of all substrings that are separated from each other by one or more blanks
Eg {"now", "is", "the", "time", "for", ...}
HERE is a practice regular expression quiz
Reminder of middle of term test!
Read JS: chpt 11 - regular expressions
