Connection Framework

J2ME (Java 2 Platform, Micro Edition) provides various connectivity APIs to allow mobile devices to communicate with servers and other devices.

Some of the connection APIs provided by J2ME include:

HTTP Connection: This API allows mobile devices to connect to web servers and retrieve data using the HTTP protocol.
HTTPS Connection: This API is similar to the HTTP connection API, but it uses a secure SSL/TLS layer for encryption and authentication.
Socket Connection: This API allows devices to establish a low-level network connection using TCP/IP, enabling data exchange with servers and other devices.
Bluetooth Connection: This API enables wireless communication between devices using Bluetooth technology.
Datagram Connection: This API enables devices to exchange small packets of data with each other using the UDP protocol.

By providing these connectivity APIs, J2ME makes it easier for developers to create mobile applications that can communicate with servers and other devices, enabling a wide range of mobile services such as email, social networking, and multimedia content delivery.
