私はコーディングスキルを向上させるためにtick-tac toeをコーディングしようとしています。以前のプロジェクトでは、新しい画面を作成するために、新しいJFrameを作成し、それを表示可能に設定し、もう1つを表示しないように設定しました。しかし、このプロジェクトでは、JPanelsを使用してpanelOneを削除し、panelTwoを追加することにしました。私はこの主題に関する以前のStackOverflowの質問を見て、それをいくつかの変更を加えて自分のコードにインポートしました。JFrameがフレームにJPanelを追加していません
私の場合、コードはpanelOneを削除していますが、panelTwoは追加していません。私のコードは以下の通りです。
package Main;
import javax.swing.JFrame;
public class MainFrame extends JFrame {
public MainFrame() {
initComponents();
}
void swapPanel(){
new Thread(new Runnable(){
@Override
public void run() {
MainFrame.this.remove(panelOne);
MainFrame.this.add(panelTwo);
MainFrame.this.invalidate();
MainFrame.this.revalidate();
MainFrame.this.pack();
}
}).start();
}
void singlePlayer(){
swapPanel();
}
void multiPlayer(){
swapPanel();
}

私は両方のパネルを設計するためにNetBeansを使用しています。
ご協力いただきましてありがとうございます。
あなたはイベントディスパッチスレッド以外のスレッドからSwingコンポーネントにアクセスすることはできません。 https://docs.oracle.com/javase/tutorial/uiswing/concurrency/をお読みください。私はそれを行うスレッドを開始するためのreaonは表示されません、あなたはあなたがやっていることを達成するためにCardLayoutを使う方がよいでしょう。それがそれのためのものです。 –
私は新しいスレッドを削除して、同じように動作します。 CardLayoutについて聞いてもよろしいですか？ありがとうございました。 –
あなたはドキュメントを読んで、何かを試してみてはいかがですか？ https://docs.oracle.com/javase/tutorial/uiswing/layout/card.html –
