【正文】 which uses paper materials. Nowadays, PDA phone and other mobile instruments have explored a very broad way in this society. Mobil elective course system is one another system which uses the inter to choose course. There are a few of soft wares appearing on the inter about course electing. However, there are little soft wares have the functions about Mobil elective course system. Under this situation, this system wrote this essay mainly talking about how to broadly use the Android system to design and explore Mobil elective course system. This essay as the supplementary ways based on some existing inter course electing systems is mainly to provide convenient and efficient ways for students’ course electing needs. After the basic study about the Android system exploration and the Java Servlet programming technology, this system bined the Mobil inter’s characters to get a summary which is about Mobil elective course system main functions. Through some system exploitation this system made a project about it. This system has some parts such as: system register, course elective information, course electing, course canceling, checking about the chosen courses, etc. During this designing process, this system used C/S and Http. The server uses JDBC date resource to municate. The phone use flow as the way to receive date from Web server.

的教學(xué)管理系統(tǒng)在高校日趨廣泛，伴隨著學(xué)年制管理體制向?qū)W分制管理體制的發(fā)展，使得網(wǎng)上選課系統(tǒng)在高校中 得 到廣泛的應(yīng)用 。有時(shí)為了選擇到自己喜歡的課程，往往要 提前半小時(shí)到一個(gè)小時(shí)在計(jì)算機(jī)上登錄選課系統(tǒng)，守候在計(jì)算機(jī)旁邊，而不能做到隨時(shí)隨地的選課。因此， 學(xué)生需要另一種的選課系統(tǒng)來(lái)解決當(dāng)前選課系統(tǒng)存在的問(wèn)題，來(lái)分流由于傳統(tǒng)網(wǎng)絡(luò)訪問(wèn)給服務(wù)器帶來(lái)的壓力。 基于上述考慮， 客戶端與服務(wù)器之間的通信采用 Http 通信協(xié)議。同時(shí)，為今后開(kāi)發(fā) 出 適合我校 情況 的移動(dòng)選課系統(tǒng)打下基礎(chǔ)。隨著移動(dòng)互聯(lián)網(wǎng)的發(fā)展這種 B/S 模式的選 課系統(tǒng)也存在很多不足，比如要進(jìn)行選課操作 時(shí) ，就必須坐在接入網(wǎng)絡(luò)的電腦前 ： 而且課程開(kāi)設(shè)的通知等等也是要通過(guò)上網(wǎng)才知道，對(duì)于一些不常上網(wǎng)的同學(xué)可能就會(huì)錯(cuò)過(guò)很多有用的消息，比如說(shuō)課程調(diào)整通知、考試安排等等。而智能手機(jī)操作系統(tǒng)中， Android 系統(tǒng)的市場(chǎng)份額又遠(yuǎn)遠(yuǎn)大于其他的手機(jī)操作系統(tǒng)。 基于 Android 的移動(dòng)選課 系統(tǒng)意義 基于 Android 的移動(dòng)選課系統(tǒng)的用戶無(wú)論是 在公交車(chē)，在商場(chǎng)，還是在沒(méi)用電腦的宿舍。可以通過(guò)訪問(wèn) Wind
