What is WebSocket API in Java?

The WebSocket API in Java is a protocol that enables full-duplex communication channels over a single TCP connection, facilitating real-time data transfer between clients and servers. This is particularly useful in applications that require instant communication, such as chat applications, gaming, and live notifications.

Using WebSockets in Java can significantly enhance the performance of web applications by reducing latency and improving interactivity. The Java API for WebSocket is part of the Java EE specification and provides a simple way to create WebSocket applications.

Below is a simple example of a WebSocket server in Java using the Java API for WebSocket:

import javax.websocket.OnMessage; import javax.websocket.Session; import javax.websocket.server.ServerEndpoint; @ServerEndpoint("/websocket") public class MyWebSocket { @OnMessage public void onMessage(String message, Session session) throws IOException { session.getBasicRemote().sendText("Echo: " + message); } }
