我正在尝试使用其他表单制作现有表单。 我想单击一个按钮，然后显示另一个表单。这是我写的：
import javax.swing.JFrame;
public class CustomerUI extends JFrame {
public CustomerUI(java.awt.Frame parent, boolean modal)
{
initComponents();
setTitle("Customer Data Input");
setLocationRelativeTo(null);
pack();
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setVisible(true);
}
@SuppressWarnings("unchecked")
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
Customer c = new Customer(jTextField1.getText(), jTextField2.getText(), jTextField3.getText());
CinemaUI form = new CinemaUI();
form.CUST.SetName(jTextField1.getText()); //Customer's Name
form.CUST.SetID(jTextField2.getText()); //Customer's ID
form.CUST.SetCard(jTextField3.getText()); //Customer's card
form.NUM_OF_SEATS = Integer.parseInt(jTextField4.getText()); //Number of seats
form.pack(); //Shows the next Form
form.setVisible(true);
CustomerUI.this.setVisible(false); //Hides this Form
}
/**
* @param args the command line arguments
*/
public static void main(String args[]) {
/* Create and display the dialog */
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
CustomerUI dialog = new CustomerUI(new javax.swing.JFrame(), true);
dialog.addWindowListener(new java.awt.event.WindowAdapter() {
@Override
public void windowClosing(java.awt.event.WindowEvent e) {
System.exit(0);
}
});
dialog.setVisible(true);
}
});
}
}
CinemaUI是我想要打开的表单的名称。
单击jButton1（我要打开新窗口的那个）后，出现以下错误：

修改
我会尝试解释我的目标是什么：
某个人想要订购电影票。我使用文本框保存他的数据（姓名，信用卡等），然后继续选择该人的座位。我正在看的第一个窗口是带有文本框的窗口，在我单击一个按钮后，我希望窗口显示可用席位列表（CinemaUI）。
再次感谢您的帮助，我很抱歉这么久。

我认为你正在寻找这样的东西：
public class Form extends JFrame {
public Form(){
JButton show = new JButton("show Form2");
show.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
new Form2();
Form.this.setVisible(false);
}
});
setTitle("Form 1");
getContentPane().add(show,BorderLayout.CENTER);
setLocationRelativeTo(null);
pack();
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setVisible(true);
}
class Form2 extends JFrame {
public Form2(){
JButton show = new JButton("show Form");
show.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
new Form();
Form2.this.setVisible(false);
}
});
setTitle("Form 2");
getContentPane().add(show,BorderLayout.CENTER);
setLocationRelativeTo(null);
pack();
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setVisible(true);
}
}
public static void main(String[] args) {
new Form();
}
}
我希望它可以帮到你。
根据您Form提供凭据表格，Form2为CinemaUI。

错误...没有关于CinemaUI实现的任何细节，它将有点难以帮助。我们假设CinemaUI扩展了JFrame。你确定先打电话给pack（）吗？如果它不是一个框架，你可能已经处于某种框架......所以你应该首先添加CinemaUI。

我发现了我的问题。我应该制作一个新的JFrame，而不是一个新的“类”。这样就可以使用这个例子了：
Form1 form = new Form1();
form.setVisibile(true);
this.setVisibile(false);
