タイトルが示すように、Java 画面が空白のままになります。クラスの形状と 2 つのラベルを表示したいと考えています。線と x の描画を処理する他のクラスを見たい場合はお知らせください。これは私がこれまでに持っているものです:
- -編集 - -
アドバイスをいただいたので、少し前進しました。Shapes の paint メソッドから適切なコードを削除し、それを別のメソッドまたは新しいクラスに移動してクリーンに保ちました。Shape's はまだページを白紙にして作成していますが、状況は良くなっています。また、回答のコードを貼り付けないでください。学生として、私はコードをコピーしないように指示されました。「3 つの for ループを作成し、整数を作成する」などの指示は、許容されると見なされます。ありがとうございました!皆様大変お世話になりました!
---編集--- 先生と話した後、シェイプのグラフィカル コンポーネントを分離し、ムーブに配置することに成功しました。形状は、質問をして適切に機能することを知っています。Moves がすべてを描画するには、まだいくつかの調整が必要だと思いますが、すべてがより良く機能するようになると思います。今の姿をお見せします。私が正しい軌道に乗るのを手伝ってくれてありがとう!
