Prints information about Java class files Generates header files from Java class files GCJ has two parts: the compiler and the runtime support library. The differences between platforms are mostly limited to filename extensions. A First Look at GCJįor the rest of the article, I will use Red Hat Linux 8.0 as my platform.

Users of other platforms may get binary distributions of GCC from their favorite download centers.

Windows users need to visit the MinGW Download page and get the following two files:Īnd install both into a common directory ( C:\MinGW will work fine.) Other Platforms To install GCJ on a Red Hat Linux 8.0 system, simply run GCC is bundled with most Linux distributions. In this article, I will first take you on a tour of GCJ basics, and then show some more advanced features.

However most other Java features are supported, including collections, networking, reflection, serialization, JNI and RMI. GCJ's Java implementation is not complete.

GCJ native code can be executables or shared libraries. It can also compile Java bytecode to native machine code. It can compile Java source code to either Java bytecode (class files) or native machine code. Support for Windows using MinGW is also available. Currently at version 3.2.1, it is supported on GNU/Linux on Pentium, Itanium, Alpha, PowerPC and AMD Hammer, FreeBSD on Pentium, Solaris on SPARC and more. GCJ, a radically traditional (*) Free Software implementation of the Java language, has been part of GCC since the 3.0 release in June 2001.

The splash-screen window has an overlay surface with an alpha channel, and this surface can be accessed with a traditional Graphics2D interface.By Weiqi Gao, OCI Principal Software Engineer Typically, a developer wants to keep the splash-screen image on the screen and display something over the image. If the application has not created the splash screen at startup through the command-line or manifest-file option, the getSplashScreen method returns null. Only a single instance created within this class can exist, and this instance can be obtained using the getSplashScreen() static method. An application cannot create an instance of this class. SplashScreen class is used to close the splash screen, change the splash-screen image, obtain the image position or size, and paint in the splash screen. The figure below represents an example of the Java application splash screen developed as an animated gif file. The splash screen can display any gif, png, or jpeg image, with transparency, translucency, and animation. A Java application launcher is able to decode an image and display it in a simple non-decorated window. The resulting delay of several seconds has made the use of a Java™ technology-based splash screen less than desirable.įortunately, Java™ SE 6 provides a solution that allows the application to display the splash screen much earlier, even before the virtual machine starts. Before the splash screen can pop up, the application has to load and initialize the Java™ Virtual Machine (JVM), AWT, Swing, and sometimes application-dependent libraries as well. However, because the main purpose of a splash screen is to provide the user with feedback about the application's startup, the delay between the application's startup and the moment when the splash screen pops up should be minimal. Java Foundation Classes, both Swing and Abstract Windowing Toolkit (AWT), enable a developer to create splash screens in Java technology applications.

Almost all modern applications have a splash screen.
