JDK (Java Development Kit) Tutorials

∟Datagram Network Communication

This chapter provides tutorial notes and example codes on datagram network communication. Topics include introduction to datagram communication; creating a datagram server and listening for incoming packets; creating a datagram client and sends packets to a server; sample programs: DatagramServer.java and DatagramClient.java.

What Is a Datagram?

Establishing a Datagram Communication Link

DatagramServer.java - A Datagram Server Application

DatagraClient.java - A Datagram Client Application

Conclusion:

• JDK java.net.DatagramSocket class allows us to create a server or client datagram socket with receive() and send() methods.
• JDK java.net.DatagramPacket class allows us to create a datagram packet to be transferred between the server and the client.

Notes and sample codes bellow are based on JDK/J2SDK 1.4.1_01.
