Online Documentation

The complete documentation is available at http://java.sun.com/docs/index.html. Specifically, you will be most interested in http://java.sun.com/j2se/1.3/docs/api/index.html. You may want to download it for faster response. However, if you are running on a windows platform, we recommend downloading and using the WinHelp version of the software. Download it at http://www.confluent.fr/javadoc/jdk13e.html. Just extract it to your choice of directories and double click on JDK13.HLP.

On Line Tutorials

Java Database

Java Native Interface (JNI) allows you to call Java from C.

Here is another tutorial from the sun web site.

Individual Books

Example Programs from Books

If there is something you want to do in Java, you can generally find an example program for free. We recommend you download the following links and use the Linux find | grep command or the windows find/search program to search for an example program that already has the feature demonstrated.

AWT

For example, if you want to write applets, you probably want to use AWT instead of SWING. Unfortunately, the Java AWT book from O'Reilly seems to be unavailable these days, but the source code is still available to download! (The source code was the best part anyway because this was more of a reference book than a tutorial). It contains lots of great examples that will still compile if you use the "-depricated" qualifier on the command line. These examples seem to be the best source of information on programming GUI without SWING. We've been in the process of translating the sample program from the Java 1.0 event model to the Java 1.2 model.

Basic Tutorials

Some more great Java code can be found in Java Examples in a Nutshell, 2nd Edition at http://examples.oreilly.com/jenut2/2nd_edition/ -- this contains one of the few examples of using UDP (instead of TCP/IP) for network communication.

The WROX site has free source code for Professional Java Fundamentals and Beginning Java 2.

The Java Tutorial is an extensive full text tutorial on applets, beans and other basic topics.

Freejavaware.com has an extensive list of online tutorials on line.

IPlanet.com has some samples demonstrates many exotic things like Javascript to Java function calls, JDBC, server side Java applets, file uploads and more.

Performance Tuning

http://java.sun.com/docs/books/performance/ contains code concerned with measuring performance.

Java Native Interface (JNI)

The Addison Wesley book from SUN.

Download the code for Essential JNI using these instructions.

$ ftp ftp.prenhall.com
cd /pub/ptr/professional_computer_science.w-022/gordon/essential_jni
binary
get ejni_ex.zip

If your web browser supports ftp directly try clicking here: ftp://ftp.prenhall.com/pub/ptr/professional_computer_science.w-022/gordon/essential_jni

General Java

The Java Cook Book contains many examples including a nice implementation of grep.

This book uses the regular expression library from http://jakarta.apache.org/oro/ which you must download.
