JAVA-API Datagramsocket Datagram Socket class

1. Datagram Socket class

The Datagramsocket class, the socket used to send and receive datagram packets.

Datagramsocket Construction Method

Structuring method formats	Description
Public Datagramsocket()	Constructs a datagram socket, binds to any locally determined available port
Public datagramsocket(int port)	Socket bound to the specified port
Public datagramsocket(int port, inetaddress laddr)	Binds to the specified port, the specified address

1.1. Send data

Send datagram packet data using the Send method of the Datagramsocket class.

1.1. Create a Send Socket object

You can use the constructor directly to generate it.

1.2. Create data and package

Java provides a class called the "datagram Packet" class that uses the class new object, which is the datagram packet we are sending.

1.3. Send data

1.4. Releasing Resources

1.2. Receiving data

Receive datagram packet data using the Receive method of the Datagramsocket class.

1.2.1. Create a Receive socket object 1.2.2. Receive data 1.2.3. Parse data 1.2.4. Output data 1.2.5. Releasing resources 2. Datagram Packet class

This class, which means "datagram packets", is used to implement a no-connection packet delivery service.
