equals, hashcode, toString,
- Illustration of using reflection to invoke main
- Using accessible fields to get private data
- Illustration of the proxy pattern.
Shows generation by hand, generation by using Java 1.3 dynamic proxies,
and an approximation of what
the dynamic proxy is actually producing for you behind the scenes
- Sept 10, 12, 17: Threads and Synchronization
- PDF slides
- Illustrates basics of getting threads to run:

- Series of examples using an Account.
Some threads do deposits, some do withdraws on shared account.

- Sept 19: Networking
- Sept 24: Server-side Programming
- PDF slides
- JSDK 2.1 download for Windows (375K)
- This material is not in the text. Additional references:
- For all Java examples, save the HTML in main folder, place the
class files in your WEB-INF/servlets directory, and start the servletrunner.
The links will not run directly from my web page because
our web server is not running servlets.
- CGI program in C++ to print out what a form transmits.
prog1.html (uses POST), and
prog1b.html (uses GET).
- CGI script can be invoked from a Java program, so you cannot
assume the form has done verification:
- Findmax program using a servlet:
- Program to render PDF files (assumes get, so include
name of file, minus .pdf extension after a ? in the URL):
- Cookie example from slides:
- Session example from slides:
- Sept 28: Review of Old Stuff
- Oct 1: Serialization
- Oct 3: Exam #1 covers Object class, reflection, threading, networking
- October 8: Garbage Collection
- Java Developer Connection Article
shows that soft references don't stay around for a long time.
shows a factory class that hands out Foo objects
(from a pre-allocated pool),
but requires that the client release the objects back to the pool.
shows a factory class that hands out Foo objects,
but does not require that the client release the objects.
Instead it uses weak references to detect orphaned Foo objects,
and reclaims those orphans for the pool.
