The document provides an overview of Java 2 Platform, Micro Edition (J2ME): J2ME is a Java platform for resource-constrained devices. It defines configurations like CLDC for very limited devices and CDC for more capable devices, as well as profiles like MIDP that add functionality. MIDP targets mobile information devices and defines APIs for user interfaces, storage, and networking. Developing for J2ME requires choosing a configuration and profile, then building a MIDlet application within their constraints.
