differences between UDP and TCP. One is that it does not need to establish a connection, and the other is that it retains the message boundary in each message sent and received.Server Because UDP does not need to establish a connection, the process is as follows: 1. Construct an initramsocket instance and specify the local port. 2. Use the receive method of the initramsocket instance to receive the contents of the communication in the middle of DatagramPacket. DatagramPacket. 3. Use the send an

is as follows:1. Construct the Datagramsocket instance, specifying the local port.2. The Receive method of the Datagramsocket instance receives the content of the communication in the middle of the datagrampacket.datagrampacket.3. Receive and send Datagrampacket through the Datagramsocket send and receive methods.The typical interaction process code is as follows:1. Build the Datagramsocket instance, specifying the local port. Datagramsocket socket = new Datagramsocket (servport);//2. Build Dat
