Networking and TCP IP Connection

J2ME (Java 2 Platform, Micro Edition) is a platform designed for embedded systems and mobile devices. Networking in J2ME involves connecting devices to a network, such as the internet, and transmitting data between them.

TCP/IP (Transmission Control Protocol/Internet Protocol) is the standard protocol used for networking in J2ME. It is a set of rules that govern how data is transmitted and received over a network. TCP is responsible for establishing a reliable, ordered, and error-checked connection between two devices, while IP is responsible for routing packets of data between devices over the internet.

J2ME includes classes for TCP/IP networking, such as the javax.microedition.io.Connector class, which allows a connection to be established between two devices, and the java.io and java.net packages, which provide classes for reading and writing data over a network connection.

To establish a TCP/IP connection in J2ME, you need to create a Connection object using the Connector class, specify the type of connection (such as socket, datagram, or server), and then use the I/O classes to transmit data over the connection.

Overall, TCP/IP networking is an essential component of J2ME programming for mobile devices and embedded systems, enabling devices to connect and communicate with each other over the internet.
