Java实现简单的socket通信教程
今天学习了一下java如何实现socket通信，感觉难点反而是在io上，因为java对socket封装已经很完善了。
今天代码花了整个晚上调试，主要原因是io的flush问题和命令行下如何运行具有package的类，不过最后问题基本都解决了，把代码贴出来供大家参考
server
publicclassTcpServer{
publicstaticvoidmain(String[]args)throwsException{
ServerSocketserver=newServerSocket(9091);
try{
Socketclient=server.accept();
try{
BufferedReaderinput=
newBufferedReader(newInputStreamReader(client.getInputStream()));
booleanflag=true;
intcount=1;
while(flag){
System.out.println(客户端要开始发骚了，这是第+count+次！);
count++;
Stringline=input.readLine();
System.out.println(客户端说：+line);
if(line.equals(exit)){
flag=false;
System.out.println(客户端不想玩了！);
}else{
System.out.println(客户端说：+line);
}
}
}finally{
client.close();
}
}finally{
server.close();
}
}
}
client
publicclassTcpClient{
publicstaticvoidmain(String[]args)throwsException{
Socketclient=newSocket(127.0.0.1,9091);
try{
PrintWriteroutput=
newPrintWriter(client.getOutputStream(),true);
Scannercin=newScanner(System.in);
Stringwords;
while(cin.hasNext()){
words=cin.nextLine();
output.println(words);
System.out.println(写出了数据:+words);
}
cin.close();
}finally{
client.close();
}
}
}
补充知识：
