DatabaseName=testusername=scottpassword=123456maxActive=10maxIdle=5maxWait=2000要执行SQL语句，必须获得java.sql.Statement实例， Statement接口提供了三种执行SQL语句的方法：executeQuery 、executeUpdate 和execute，具体实现的代码： ResultSet rs = stmt.executeQuery(SELECT * FROM .) ; 3.2 数据库的创建为了实现网吧的正常运营与管理，数据库中的以下表格是必不可少的，在此系统中我们用的是sqlserver数据库。（1） 卡号表，表结构如图7所示，用来存储已注册的卡信息图7 卡表（2） 机器表，表结构如图8所示，用来存储该网吧存在的电脑信息图8 机器表（3） 上机下机表，表结构如图9所示，用来存储客户上机对应的机器号，上机时间及下机时间，所用费用的用户信息图9 上机下机表4.1.2数据库的创建（1） 创建卡表CREATE TABLE dbo.card(CARDID varchar(10) NOT NULL,USERNAME varchar(10) NOT NULL,PASSWORD varchar(20) NOT NULL,BALANCE numeric(5, 2) NULL,STATE numeric(1, 0) NOT NULL,)（2） 创建机器表CREATE TABLE puter(COMPUTERID varchar(10) NOT NULL,STATE numeric(1, 0) NOT NULL,REMARK varchar(50) NULL,)（3） 创建上机下机表CREATE TABLE dbo.record(RECORDID numeric(5, 0) NOT NULL,CARDID varchar(10) NOT NULL,COMPUTERID varchar(10) NOT NULL,BEGINTIME char(19) NOT NULL,ENDTIME char(19) NULL,FEE numeric(5, 1) NULL,)4. 总结本网吧计费系统在整个开发过程中采用了面向对象的开发方法，利用Java技术对整个的网吧计费工作流程进行了模拟、设计与实现。整个系统代码的编写过程，都体现了面向对象开发方法的优越性。另外，该网吧计费系统采用的后台数据库为SQL Sever，该数据库在设计与开发的过程中也起到了至关重要的作用，体现了该数据库系统的强大功能。通过这次课程设计，使我灵活应用所学数据结构知识，独立完成问题分析，结合数据结构理论知识，编写程序求解指定问题。初步掌握软件开发过程的问题分析、系统设计、程序编码、测试等基本方法和技能；提高综合运用所学的理论知识和方法独立分析和解决问题的能力；并用系统的观点和软件开发一般规范进行软件开发，巩固、深化学生的理论知识，提高编程水平，并在此过程中培养我们严谨的科学态度和良好的工作作风。总的来说，在这次的课程设计中遇到了不少的问题，大部分得到了很好的解决，但也有少部分遗留的问题。最后就是从一而终的问题了，在开发过程中我遇到了许许多多的问题，很多地方都不明白，经常有打退堂鼓的想法，我经常的请教同学和老师，最后的成果虽然不很完美，但我尽力了，并有所收获这次的课设对我来说十分重要，因为毕业设计可能会用到JAVA来实现的相关编程。而且这次的课设也让我对JAVA面向对象的设计有了很深的体会。参考文献1 吕凤翥,马皓.
