Syllabus and course policies.

This is the website for course assignments, notes and other resources. Blackboard is used for submitting homework, conducting discussions and tracking grades.

Disk Drive I use in the Lectures.

BookClasses Java Files: Download individual lost ones from here!!

In the Lab (ITSUNIX), you can copy them from

/usr/local/depts/cs/geintro/bookClasses

Week by week plan

What will happen in lectures:

  1. iClicker polls and quizzes on reading and lecture questions, that will count toward your grade!
  2. Live demos of programming in Java! Watch your professor get stuck on syntax errors and bugs!
  3. Hands-on paper problem solving and doing what computers do yourself!
  4. Notes scribbled electronically by professor and presentation materials that you don't have to copy because they will go on the Web!
  5. Sometimes, cool, corny videos from UTube or visits to other cool web sites!
  6. Discussions to clear up confusion before getting frustrated at the computer!

Week 1

GLOBAL GAME JAM...Join the Prof. and others..at Albany's instance of the Jam class!

Day Readings/Assignments/Topics Resources
Labs no labs first week;
C01 Thu Jan 19
  • iClicker policy
  • Computing on paper tickets (Euclid's algorithm using subtraction)
  • The same computation on Java variables in DrJava's interaction window.

Week 2

Readings: GE: Whole preface(!) 2.2 2.3.1 2.3.2 2.4.1 2.4.2 2.4.3 2.5.1 2.5.2 3.4("we" means Guzdial&Ericson in 3.4.1, not you!); after Thursday, 3.5

Week 3

Readings: Finish reading about programming Turtles (3.4) and read about creating (means writing your own) methods(3.5)

Day Readings/Assignments/Topics Resources
Labs
  • Read (3.4) BEFORE lab..bring it in, too!
  • Download book-classes into your ITSUNIX home directory (is your UA S: drive)
  • Write comlete programs that make Turtles draw cool simple figures.
  • After lab, find them on your S: drive or ssh access to itsunix.albany.edu and upload a complete Java program to Blackboard for grading and credit.
C04 Tue Jan 31
C05 Thu Feb 2
  • Introduce the Web copy of the USB drive directory in which in-class programs are developed.
  • Demonstrate a run of, then explain line-by-line, the program from Lecture 04
    • Reminder: In Java, = doesn't mean equals, it means copy from the right side into the "ticket" named on the right.
    • Demo of opening and compiling the World.java file in the book-classes directory, when World was announced as an unknown class World symbol.
  • Do NOT go beyond one letter until after you know how to make and use your own methods with parameters effectively: The reading topic of 3.5. Otherwise you will waste your time!
  • Demonstrate a workflow of renaming and saving over and over to capture a history of versions.
  • Changing pen width,
    • how the order of Java program statements matters
    • programming requires good guesses and choices sometimes; precise decisions are needed.
    • Graphics coordinate system
    • moving Turtle to the corner
    • lifting pen before move and lowering it after.
  • Began to develop code to scale a letter--up to scaling only its first stroke.

    Compilation error from passing a double to the Turtle's forward( int ) method detected and fixed with

    mt.forward( (int) (defMoveLen*scale) );

    The multiplication is done with floating point numbers and then the fractional part is thrown away to get an integer number of pixels.

  5. V5 ball method draws a ball where color ranges from white in the center to green on the edges (Fixed right after class by a student!) (illustrates the need to explicitly write cast to throw away the fraction when the double returned by the weAv method is truncated to an int.
