Java Platform, Micro Edition (Java ME)
- This edition is geared toward applications embedded in consumer products such as cell phones, PDAs, set top boxes, smart cards, and car navigation systems.
- One thing that distinguishes J2ME from the other editions is that it is the only one that is subdivided into profiles and configurations.
- A profile defines libraries for different platforms and the JVM requirements for supporting a particular micro platform (for example, there is one profile for
PDAs and another for wireless devices).
- A configuration is composed of a virtual machine and a small set of libraries that provide base functionality to devices. Currently there are two configurations:
Connected Limited Device Configuration and Connected Device Configuration.
- A runtime is included, which takes a very small footprint.
- The smart card runtime in the Card Virtual Machine, for example, consumes only 128K of memory.
Latest release : Java Platform Micro Edition SDK 3.0
