TA availability (lab submission errors/problems)

If you have a lab submission problem, the VERY LAST TIME to get these resolved is 5/17/07, from 11-12. TAs will be at their trailer desks. Go see them. After noon on this day, lab grades will stand and will not be changed. A solution to one version of exam 3 is available. Note that for question 1 a possible answer is written after each item, but nothing is circled in the code.

Exam 3 pick-up

I will be available for exam 3 pick-up tomorrow (Tuesday) between noon and 1:00 PM.

Exam 3 grade adjustments

Two things you might be interested in:

I regraded part of question 1, which resulted in some students getting 2 more points, some 4 more points.
Because most students did very poorly on question 3 (which was worth 15 points), I graded the exam out of 85 rather than 100. The maximum grade for exam 3 was capped at 100.

I will be in today

I will be in today, but probably not before 10. I will be available until about 1:30.

Topics for the final exam

You are responsible for the following topics for the final exam:

Modularity and decoupling of functionality, in the context of examples from lecture
Arrays
Arraylists
Fields
Constructors (esp. to initialize fields)
Accessor methods
Mutator methods
Methods that return values.
While loops (both unnested and nested)
Modifying pictures by modifying pixels (i.e. if I give you the method to call, like setRed, then you should be able to set up the correct nested loop structure to call that method on each Pixel in the picture.
Methods with parameters.
Conditional statements (if statements and if-else statements).
The concept of a 'type' in a programming language, and how this is tied to the underlying representation scheme used to encode data of that type.
The form and function of variable declarations (local variables, parameters and fields).
The relationship between a class and an instance (or object) of a class.
How to create an instance of a class, using 'new' and a constructor for the class.
How to call a method on an object (both with and without parameters).
The basic structure of a class definition.
The basic structure of a constructor definition.
The basic structure of a method definition.
The form and function of assignment statements.
The form and function of while loops.

Office hour

Since classes are over, I am not holding regular office hours. A limited number of appointments can be arranged.

Office hour changes (Week of 05-01-07)

Carlos: W 1-3
Jason: Th 1-3
Jim: Th 12-2 (in Bell 340 lab)

Alphonce office hour change (4-25-07 and 4-26-07)

Because I will be watching team presentations for CSE116 during CSE116 recitation times, my regular office hours will this week run as follows:

Wednesday, 3:30 PM - 5:30 PM
Thursday, 9:00 AM - 10:00 AM

Alphonce office hour change (4-11-07)

Due to an Engineering-wide faculty meeting, my office hours will run from 2:10-3:10 on Wednesday 4-11-07.

Topics for second exam

You are responsible for the following topics for the second exam:

New topics for second exam

Methods that return values.
While loops (both unnested and nested)
Modifying pictures by modifying pixels (i.e. if I give you the method to call, like setRed, then you should be able to set up the correct nested loop structure to call that method on each Pixel in the picture.
Methods with parameters.
Conditional statements (if statements and if-else statements).

While you will not be directly tested on topics covered for the first exam, you need to understand them to be able to do the material for the second exam:

The concept of a 'type' in a programming language, and how this is tied to the underlying representation scheme used to encode data of that type.
The form and function of variable declarations.
The relationship between a class and an instance (or object) of a class.
How to create an instance of a class, using 'new' and a constructor for the class.
How to call a method on an object (both with and without parameters).
The basic structure of a class definition.
The basic structure of a constructor definition.
The basic structure of a method definition.
The form and function of assignment statements.
The form and function of while loops.

Office hour updates, week of 3/5 - 3/9

Prof. Alphonce's office hours on Wednesday, March 7, will run from 2:30 to 4:00.
Prof. Alphonce's office hours on Thursday, March 8, are cancelled.
Carlos' Tuesday office hours will run 1:30-2:30 instead of 2:00-3:00.

Typo correction to lab #3

Please note the following correction to the ending coordinate in exercise 3:

Exercise 3
Write a pair of nested while loops to draw a red rectangle whose upper left-hand corner is at (17,34) and whose lower right-hand corner is at ~~(50,34)~~ (50,60).

Electronic gradebook

To access the electronic gradebook, use your regular username. Your password is derived from your person number as follows. Suppose your person number is 12345678. Divide your person number into four two-digit numbers (12, 34, 56, and 78 in the case above), and multiply them together. If I did my math right, 12 * 34 * 56 * 78 is 1782144, which would be your password.

Office hour cancellation

My regular office hours on Thursday, February 22, are cancelled.

Temporary office hour change

On Friday 2/16 only, Jason will hold his office hours from 3:30-5:30 instead of his usual 1:00-3:00 timeslot.
