私は現在、ソフトウェアエンジニアリングクラスのシミュレートされた株式市場に取り組んでいます。私は現在のメニュー項目のそれぞれについて新しいウィンドウを開くためにアクションリストを使用しています。しかし、クラスごとに1つのActionListenerしか使用できないようですので、すべてのメニューオプションに対して1つのセットウィンドウしか持てません。複数のアクションリスナーを実装する他の方法はありますか？これを行う別の方法がありますか？あなたは、代わりに、ActionListenerインタフェースを実装して何かするJButtonまたはその他のオブジェクトのために必要なさまざまな機能を提供する匿名クラスを作成する必要はありませんJava：同じクラスの複数のActionListeners？

はい、あなたは単純に行うことができます。 'comp.addActionListener（new ActionListener（）{public void actionPerformed（ActionEvent e）{//ここにコードを入れて}}）;' – 3kings

@ 3kings私がしようとしているのは、アクションリスナの中のJPaneでウィンドウを作成することです。私はあなたが言うことを試みたが、うまくいかなかった。 –
