Class data sharing (called CDS by Sun) is a mechanism which reduces the startup time for Java applications, and also reduces memory footprint. When the JRE is installed, the installer loads a set of classes from the system JAR file (the JAR file holding all the Java class library, called rt.jar) into a private internal representation, and dumps ...
Memory footprint is reduced by sharing common classes between applications that run in separate Java VMs. Unlike other class data sharing (CDS) implementations, enabling the feature in OpenJ9 requires only one step: setting -Xshareclasses on the command line when you start your application. When specified, OpenJ9 creates a memory mapped file to ...
The Java Media Framework (JMF) is a Java library that enables audio, video and other time-based media to be added to Java applications and applets. Java Topology suite: Java Topology Suite (JTS) is an open-source Java software library that provides an object model for Euclidean planar linear geometry together with a set of fundamental geometric ...
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
The platform was known as Java 2 Platform, Standard Edition or J2SE from version 1.2, until the name was changed to Java Platform, Standard Edition or Java SE in version 1.5. The "SE" is used to distinguish the base platform from the Enterprise Edition and Micro Edition platforms. The "2" was originally intended to emphasize the major changes ...
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.
These are software applications that run on the Java platform or are programmed in Java. The software in this category are primarily user applications. For other Java-based software see the following: APIs and frameworks are listed under the relevant categories Category:Java platform, Category:Java enterprise platform, and Category:Java device ...
[1] [2] Common types of applications include word processor, media player and accounting software. The term application software refers to all applications collectively [3] and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or
