描画プログラム：エラーが発生し続ける理由を把握できません

Question

私のコードに何が間違っているのかわかりません。エラーメッセージ： エラー：（122,74）java：互換性のない型：java.awt.Pointをdoubleに変換できない エラー：（119,74）java：互換性のない型：java.awt.Point （112、23）は、Java： エラーをdoubleに変換することができない方法ドロー（java.awt.Graphics） 場所：タイプjavafx.scene.shape.Circleの可変drawCircle

Answer 1

シンボル シンボルを見つけることができません

CircleにはPointを取るコンストラクタがありません。円に渡す前にポイントからX Yを取得します。
あなたはここに

Circle newCircle = new Circle(getCircleDiameter(), e.getPoint(), getCircleColor()); 

をそのインスタンスを作成しているが、あなたのサークルクラスは小文字のcを持っています。
