我在netbeans中创建了两个GUI（一个登录表单，另一个用于添加数据或其他任何内容）。
问题是，在关闭登录按钮的对话框后，我不知道如何显示其他表单。
在下面我发布两帧的源代码。 第一个用于登录，第二个用于另一个帧。
package hms;

public class Login extends javax.swing.JFrame {
/**

*/
public Login() {
setTitle("Login");
getContentPane().setBackground(new Color(255,255,255));
initComponents();
}
/**

* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.
