“期刊管理系统”系统实现
本系统用 Java语言来实现。集成开发环境采用 JBuilder2008，数据库采用 MySql。
1 系统登录界面
首先，有一个“系统登录”窗体，根据用户所输入的用户名来判断是读者还是管理 员，并分别切换至“读者查询主界面”或“管理员主界面”。

private void jbInit() { frame = new JFrame(); frame.setTitle("期刊管理系统"); frame.getContentPane().setLayout(null); frame.setBounds(100, 100, 500, 375); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
