こんにちは、ここにある colin という gui の 2 つの jbutton が正しく機能しないのはなぜだろうと思っていましたgui がスレッド "AWT-EventQueue-0" で例外を発生します java.lang.UnsupportedOperationException: 未実装のメッセージ これを変更する方法をいくつか試しましたが、ボタンが押されたときに個々の gui を表示するだけなので、役に立ちませんでした

  1. 多くの最上位コンテナーを作成する代わりにCardLayoutを使用する

  2. カードの内容を配置 userino_frame s = new userino_frame();し、motor_frame v = new motor_frame();

  3. JButtonのActionListenerからのみ、これらの 2 つのカードの間でビューを切り替えます

関数を実装するのを忘れたようです：

    private static Object getSource() {
        throw new UnsupportedOperationException("Not yet implemented");
    }

throw行を実際のロジックに置き換える必要があります。
