java Socket

服务端

ServerSocket serverSocket = new ServerSocket(9999);

//b)指定绑定的端口，并监听此端口。

---

socket=server.accept();

//调用accept()方法开始监听，等待客户端的连接

//使用accept()阻塞等待客户请求，有客户

//请求到来则产生一个Socket对象，并继续执行

---

socket.getInputStream()

BufferedReader in=newBufferedReader(newInputStreamReader(socket.getInputStream()));

//由Socket对象得到输入流，并构造相应的BufferedReader对象

---

socket.getOutputStream()

PrintWriter writer=newPrintWriter(socket.getOutputStream());

//由Socket对象得到输出流，并构造PrintWriter对象

---

客户端

Socket socket =newSocket("192.168.1.115", 5209);

//1、创建客户端Socket，指定服务器地址和端口

---

PrintWriter write =newPrintWriter(socket.getOutputStream());

//由Socket对象得到输出流，并构造PrintWriter对象

---

BufferedReader in =newBufferedReader(newInputStreamReader(socket.getInputStream()));

//由Socket对象得到输入流，并构造相应的BufferedReader对象
