以下是创建数据包的代码: importjava.net.DatagramPacket;importjava.net.InetAddress;// 创建数据包Stringmessage="Hello, world!";byte[]buffer=message.getBytes();intport=12345;try{InetAddressbroadcastAddress=InetAddress.getByName("255.255.255.255");DatagramPacketpacket=newDatagramPacket(buffer,buffer.length,b...
For TCP based program: There is a clear distinction between the client part and the server part. I mean that in the server part program, there is a socket called ServerScoket, which can be created bynew ServerSocket(port), and wait for its client's request, once it happens, it creates...

java网络编程——UDP编程 1.发送端编程 核心:构造数据包 DatagramPacket 这里面的参数是数据,数据要发送的部分(这里是0到data.length),目的ip,端口号。 之后使用创建的DatagramPacket来进行发送 2.接收端编程 将其receive在一个packet中,之后将其输出 这是它的构造器 offset是偏移量,length读的数据的长度 和TCP编程...
In following program, what is the purpose of the while loop? There are no problems with the compilation, but whether or not I have the while loop in place or not, the result is the same. I can't understand why the while loop is included. BTW, this is just an ex......
This paper extracts the features of UDP and TCP and proposes a new Reliable UDP(UDT).An object-oriented programming language Java, support many API , provides a great help for the realization of this chat program .In this thesis, combined with the JAVA object-oriented language feature and ...
