抽奖系统的JAVA实现

摘 要
某公司采用电脑抽奖的方式来销售自己的产品，其中要求用1小系统来自动产生幸运用户。系统要求有可视化的用户信息输入界面，中奖的用户信息能够以表格的方式打印，可以保存中奖用户的信息等主要功能。经分析，JAVA中丰富的窗口类可以产生可视化的用户信息输入界面，文件操作可以方便的以多种文件格式保存用户信息，JDBC-ODBC桥技术能够实现GUI同数据库的交互，事件监听器可以实现某些输入信息的检测。因此决定使用JAVA语言实现。通过1段时间的设计，系统基本功能已实现：能可视化输入用户信息，保存中奖用户信息，打印中奖用户信息。在抽奖过程中实现用户编号的滚动，给人以动态的感觉。
