Applications written for JDK1.0 used the existing Java API, but with JDK1.1 onwards, some methods have been marked as deprecated.

If you write applications that supply TCP services via the StreamSocket class, its extremely easy to determine the IP address and port of the remote connection.

While Apple currently does not offer any “Java beginner” content, there are plenty of areas dedicated to starting off with Java:

The Java Tutorial - A thorough introduction from Sun, the creators of Java
Java Discussion Forums - Mailing lists and online [...]

Sometimes you may need this information to implement a specific feature or to implement a workaround to a bug that has been fixed in later releases. Technical Note TN2110 discusses how to best do this, along with a comprehensive list of version strings for every Java release on every version of Mac OS X.

Java Applets inside Safari can be configured to run any installed Java version by using the Java Preferences application.

Responding to the application menu is discussed in the Making User Interface Decisions section of the Java Development Guide for Mac OS X. The OSXAdapter sample illustrates how to use them in a way that will still run correctly on other platforms.
