我正在開發一個工作項目，並遇到了一些障礙。該項目實際上涉及允許用戶生成XML文件。用戶首先會看到一些GUI - 這些顯示取決於在第一個GUI上進行的選擇。一旦用戶使用GUI進行操作，數據將用於填充JTable，然後一旦確認放入XML文件。在方法錯誤中關閉動作偵聽器中的JFrame
儘管聽起來有點複雜，但我已經遇到了JFrames的問題。一旦用戶填寫了其中一個GUI屏幕上的信息並點擊了「確認」按鈕，我希望該JFrame消失，然後出現下一個。我沒有問題得到下一個出現，但由於類的設計，我無法弄清楚如何正確使用JFrame.dispose（）方法。我會後我下面的類：

public static void main(String args[]){
AllGUI aGUI = new AllGUI();
aGUI.createAllGUI();

mainPanel.add(confirmPanel,BorderLayout.CENTER);
return mainPanel;

private void addComponent(Container container, Component component, int gridx, int gridy, int gridwidth

}
}
具體來說第一GUI JComboBox時選擇將確定下一個GUI出現。
confirmButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
}else if(fileTypesComboBox.getSelectedIndex()==1){
type="HOME";
}else if(fileTypesComboBox.getSelectedIndex()==2){
type="CLEARED";
}
}
});
所以現在我只有邏輯，如果用戶選擇JComboBox中的第一個選項。這可以正常工作，並且新的GUI會打開，但它只是在第一個JFrame之上打開。
if(fileTypesComboBox.getSelectedIndex()==0){
type="OTC";
JFrame.dispose();
TCRSpecificGUI tcrGUI = new TCRSpecificGUI();
tcrGUI.createTCRSpecificGUI();
但是它是由Eclipse進行標記爲錯誤：
Cannot make a static reference to the non-static method dispose() from the type Window
我明白爲什麼會出現此錯誤，什麼我已動作監聽像這樣利用內JFrame.dispose（）嘗試但問題是我不知道如何解決。我嘗試了許多方法，但似乎沒有任何工作。我真的很感謝任何幫助，讓第一個JFrame在另一個打開時關閉。
那完美！非常感謝您的幫助！ – jesric1029
