COP-4338, Programming III Lectures
Note: Links will not be alive until a day or two before class.
- July 2: Opening remarks, the Object class, Reflection,
and the Proxy Pattern
- Remarks
- Object class PDF slides
- Reflection PDF slides
- Examples
- Illustration of the correct way to override
equals, hashcode, toString,
and clone
ObjectDemo.java
- Illustration of using reflection to invoke main
InvokeMain.java
- Using accessible fields to get private data
Spy.java
- 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
TestProxy.java
- July 4: No class
- July 9: Threads and Synchronization
- PDF slides
- Examples:
- Illustrates basics of getting threads to run:
ThreadDemo.java
- Illustrates threads corrupting data:
NoSync.java
- Series of examples using an Account.
Some threads do deposits, some do withdraws on shared account.
- Two examples with multiple monitors
- Static methods have different monitors than instance methods:
StaticsAndThreads.java
- July 11: Networking
- July 11: Server-side Programming
- PDF slides
- JSDK 2.1 download for Windows (375K)
- This material is not in the text. Additional references:
- Examples:
- 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.
program1.cpp,
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:
SubmitGetForm.java,
SubmitPostForm.java,
- Findmax program using a servlet:
findmax.html and
FindMax.java,
- Program to render PDF files (assumes get, so include
name of file, minus .pdf extension after a ? in the URL):
RenderPDF.java.
- Cookie example from slides:
login.html and
CookieExample.java.
- Session example from slides:
sessionlogin.html and
SessionExample.java.
- July 16: Serialization
- July 16: Garbage Collection
- Java Developer Connection Article
- Examples
-
TestBlob.java
shows that soft references don't stay around for a long time.
-
TestFactory.java
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.
-
TestPoolFactory.java
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.
