// 1、创建客户端Socket，指定服务器地址和端口
// Socket socket=new Socket("127.0.0.1",5200);
Socket socket = new Socket("127.0.0.1", 8080);
System.out.println("客户端启动成功");
// 2、获取输出流，向服务器端发送信息
// 向本机的52000端口发出客户请求
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
// 由系统标准输入设备构造BufferedReader对象
PrintWriter write = new PrintWriter(socket.getOutputStream());
// 由Socket对象得到输出流，并构造PrintWriter对象
//3、获取输入流，并读取服务器端的响应信息
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
// 由Socket对象得到输入流，并构造相应的BufferedReader对象
String readline;
readline = br.readLine(); // 从系统标准输入读入一字符串
while (!readline.equals("end")) {
// 若从标准输入读入的字符串为 "end"则停止循环
write.println(readline);
// 将从系统标准输入读入的字符串输出到Server
write.flush();
// 刷新输出流，使Server马上收到该字符串
System.out.println("Client:" + readline);

System.out.println("Server:" + in.readLine());
// 从Server读入一字符串，并打印到标准输出上
readline = br.readLine(); // 从系统标准输入读入一字符串
} // 继续循环
//4、关闭资源
write.close(); // 关闭Socket输出流
in.close(); // 关闭Socket输入流
socket.close(); // 关闭Socket
} catch (Exception e) {
System.out.println("can not listen to:" + e);// 出错，打印出错信息
