This document provides an overview of Java sockets including how they allow for client-server communication over networks, the lifecycle of a socket server, and code examples for a socket server and clients. It discusses how sockets provide connection-oriented and connectionless services in Java using classes like ServerSocket and Socket. Diagrams depict the use cases and classes for a socket server that handles weather requests from multiple clients. Code for a WeatherSocketServer class and examples of client requests are also included.

- 3. Java Socket A socket is a communication end point Is a network programming interface Is used by a process to communicate with a remote system via a transport protocol. Needs an IP address and a port number Sockets are popularly used in client/server computing Provides two major types of services: Connection-oriented Connectionless
- 4. Java Socket – cont. Java supports client/server computing using sockets. Java supports both connection-oriented and connectionless services. Java uses Socket for clients and ServerSocket for servers in a connection-oriented environment. Java uses DatagramSocket/DatagramPacket for connectionless services.
