The Oracle Java Micro Edition (ME) Embedded Client is an application runtime that builds on the popular Java ME specification and has been designed for resource-constrained devices like e-book readers, Blu-ray Disc players, Voice Over IP telephones, televisions, set-top boxes, printers, residential gateways and more. Java ME is the best technology for resource constrained embedded devices and has seen widespread deployment across mobile handsets and digital television devices. Java ME provides device manufacturers with the full power of the Java language, a comprehensive set of APIs, industry-leading security and access to more developers than any other platform. Through its compatibility with the Java Platform Standard Edition (Java SE), the Oracle Java Micro Edition Embedded Client inherits familiar Java features and benefits from a rich development ecosystem that enables Java developers to hit the ground running. An extensive range of tools, such as the NetBeans IDE, provides sophisticated power for creating and debugging applications. At the same time, the Oracle Java Micro Edition Embedded Client capitalizes on its Java ME heritage by being specially designed for speed and efficiency on devices with limited processing power and memory.
