CometDemo-(1)

实现了用Java语言实现TCP协议的传输。(TCP protocol using Java language transmission.)

今天尝试写一个小demo实现下之前看过的代码，目的了解不同文件的数据访问，掌握如何获取前台数据，如何将数据库的数据在前端页面展示。 awt可视化界面可已实现提交数据到数据库，也可查询数据在控制台打印。 web工程：主要是web前台输入并提交数据，然后在另一页面展示数据库内容(Today, try to write a little demo to achieve before the next read the code, the purpose of understanding the data access different files, learn how to get the reception of data, how the data in the to show the front page. awt visual interface has been implemented to submit data to the , query data can also be printed on the console. web project: mainly web frontend to enter and submit data, and then display the contents of the in another page)

说明：  J2EE实现的网站资源下载系统程序。方便移植到自己的网站系统当中。(J2EE resources to achieve the website to download system programs. Facilitate the migration to your own website systems.)

带进度条简易浏览器源码主要使用了安卓的WebView控件，另外还实现了网页加载进度条，可以实现浏览器内的前进后退。半透明菜单使用的popwindow弹出菜单，另外项目中还有一个背景更换的功能的实现代码，但是不知道什么原因在我手机上没有效果。项目不大，注释比较丰富。很适合新手学习安卓的WebView控件的使用。(Progress bar simple browser source code of the main use of Android WebView control, in addition to achieve a web page loading progress bar, you can achieve forward and backward within the browser. popwindow translucent menu using the pop-up menu, in addition to the project also has a background replacement function implementation code, but do not know why I m on the phone to no avail. The project is not big, rich annotation. It is suitable for beginners learning to use Android s WebView control.)

说明：  spingsecurity的demo，初学者可根据注释和代码进行学习(Spingsecurity demo, beginners can learn from comments and code)

JScrollPane使用的练习，使用BorderLayout将JFrame布局分为左右两块(The JScrollPane exercises, using the BorderLayout layout is divided into left and right two JFrame)

java面向对象程序设计，java开发必备(java object-oriented programming, java development essential)

面向对象数据库实验，建立点线面模型,可以用来学习面向对象数据库(Object-oriented database experiments, point, line and plane model)

说明：  仓库管理系统主要包括以下功能。 1. 仓库管理：主要实现对仓库进货、出货、商品调拨和商品图片信息进行管理 2. 商品查询：主要实现查询商品的库存情况，对商品的调拨、进货、出货、缺货情况和商评的图片信息做出记录 3. 系统设置：系统设置实现供应商信息、仓库信息和账号信息的添加、删除和修改。(The warehouse management system mainly includes the following functions. 1. Warehouse management: mainly realizes the management of warehouse purchase, delivery, commodity allocation and commodity picture information. 2. Commodity inquiry: Mainly to inquire about the inventory of commodities, and record the allocation, purchase, delivery, stock out and the picture information of the evaluation of commodities. 3. System settings: System settings can add, delete and modify supplier information, warehouse information and account information.)

CLIQUE（Clustering In QUEst)是一种简单的基于网格的聚类方法，用于发现子空间中基于密度的簇。CLIQUE把每个维划分成不重叠的区间，从而把数据对象的整个嵌入空间划分成单元。它使用一个密度阈值识别稠密单元和稀疏单元。一个单元是稠密的，如果映射到它的对象数超过该密度阈值。(CLIQUE (Clustering In QUEst) is a simple grid based clustering method for the discovery of clusters based on density in subspace. CLIQUE divides each dimension into a non overlapping interval, dividing the entire embedded space of the data object into a unit. It uses a density threshold to identify dense and sparse units. A unit is dense, if the number of objects mapped to it is more than the density threshold.)
