Storage

J2ME (Java 2 Micro Edition) provides several storage options for mobile devices that have limited memory capacity. There are two main types of storage under J2ME: Record Management System (RMS) and Persistent Storage.

RMS is a lightweight database system that allows storing and retrieving data in a key-value format. It is suitable for small amounts of data, typically up to a few kilobytes. RMS is implemented using the Java ME RecordStore API, and it is supported by most J2ME-enabled devices.

Persistent Storage, on the other hand, is a more advanced storage option that allows storing data in a file system format. It provides a higher capacity for storing data, but it requires more processing power and memory. Persistent Storage is implemented using the Java ME FileConnection API, which enables access to the device’s file system.

Both storage options have their advantages and disadvantages, and the choice depends on the specific requirements of the application. However, it is important to note that the storage capacity of J2ME devices is limited, and it is essential to optimize the use of storage to ensure the best performance and user experience.
