J2ME provides an environment for applications running on consumer devices, such as mobile phones, PDAs, and TV set-top boxes, as well as a broad range of embedded devices.
Like its counterparts for the enterprise (J2EE), desktop (J2SE) and smart card (Java Card) environments, J2ME includes Java virtual machines and a set of standard Java APIs defined through the Java Community Process, by expert groups whose members include device manufacturers, software vendors, and service providers.
The J2ME Architecture
The J2ME architecture comprises a variety of configurations, profiles, and optional packages that implementers and developers can choose from, and combine to construct a complete Java runtime environment that closely fits the requirements of a particular range of devices and a target market.
Each combination is optimized for the memory, processing power, and I/O capabilities of a related category of devices.
The result is a common Java platform that takes full advantage of each type of device to deliver a rich user experience.
