我需要帮助找出如何对Movie数据库进行正确的项目，我负责或多或少地使用NetBeans IDE，这是我以前从未尝试过的，即使它就像一个视觉工作室Java的。
我遇到的问题是我想要正确地替换它。
private void btnLogoffActionPerformed(java.awt.event.ActionEvent evt)
{
setVisible(false);
LoginMovie l = new LoginMovie();
l.setVisible(true);
}
让JFrame正确关闭，以便我可以让用户或管理员返回登录JFrame，这也是由此组成的。

知道我应该编辑或更改以使其工作吗？而且这不是代码中的完成日志，因为我的同行告诉我，我从数据库中提取数据＆＃34;
