说明：  阐述MIDP JAVA网络的相关功能。由于N800终端只能使用HTTP通信，所以我们将以HTTP为主要范例进行讲解。到目前为止，只能制作终端内的单机型应用程序，如果利用网络，连接网络服务器，那么就能够制作出多种应用程序。
(MIDP JAVA elaborate network related functions. As the N800 terminal can only use HTTP communication, so we are going to HTTP as the main examples of conduct to explain. So far, only the production of single-terminal-type applications, if the use of networks, connecting the network server, then will be able to produce a variety of applications.)
