How to Use the System Tray (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
The system tray is a specialized area of the desktop where users can access currently running programs. This area may be referred to differently on various operating systems. On Microsoft Windows, the system tray is referred to as the Taskbar Status Area, while on the GNU Network Object Model Environment (GNOME) Desktop it is referred to as the Notification Area. On K Desktop Environment (KDE) this area is referred to as the System Tray. However, on each system the tray area is shared by all applications running on the desktop. The java.awt.SystemTray class introduced in Java™ SE version 6 represents the system tray for a desktop. An application cannot create an instance of the SystemTray class. The system tray contains one or more tray icons which are added to the tray using the add(java.awt.TrayIcon) method. Note: The add() method can throw an AWTException if the operating system or the Java runtime determines that the icon cannot be added to the system tray. ... The SystemTray API

Mastering recursive programming
For new computer science students, the concept of recursive programming is often difficult. Recursive thinking is difficult because it almost seems like circular reasoning. It's also not an intuitive process; when we give instructions to other people, we rarely direct them recursively. For those of you who are new to computer programming, here's a simple definition of recursion: Recursion occurs when a function calls itself directly or indirectly. A classic example of recursion The classic example of recursive programming involves computing factorials. An interesting property of a factorial is that the factorial of a number is equal to the starting number multiplied by the factorial of the number immediately below it. Listing 1. int factorial(int n) { return n * factorial(n - 1); } The problem with this function, however, is that it would run forever because there is no place where it stops. Listing 2. int factorial(int n) { if(n == 1) { return 1; } else { return n * factorial(n - 1); } }
Killer Game Programming in Java
Killer Game Programming in Java is for people who already know the basics of Java. For example, students who've finished an 'Introduction to Java' course. The aim is to teach reusable techniques which can be pieced together to make lots of different, fun games. For example, how to make a particle system, first-person keyboard controls, a terrain follower, etc. If you don't know Java, then Killer Game Programming in Java isn't for you. Instead, have a look at my Java book suggestions. The main emphasis of my book (over 17 chapters) is on 3D gaming using Java 3D. Early (sometimes very early) draft versions of the book's chapters can be downloaded from here (see the links below). All the book's code is here, either downloadable as a single zip file (visit the code page), or on a chapter-by-chapter basis from each chapter's page (see the links below). I've also been adding new chapters here; chapters which don't appear in the book. There's a Czech edition of my book. Dr.
