Using Forms and Items in MIDlets

RMS: This Java tip explains RMS Record Management System for storing persistent data. A record store consists of a collection of records which will remain persistent. The RMS API abstracts the device-dependent details of the storage area and access to those details, and it provides a uniform mechanism to create, destroy, and modify data. This ensures portability of MIDlets to different devices.

J2ME (JSR 179) is a set of generic APIs that can be used for developing location-based services.J2ME location APIs provide mobile applications with information about the device's present physical location and orientation in lattitude-longitude-altitude, and support the creation and use of databases of known landmarks, stored in the device.
