Java を使用して潜水艦ゲームを作成するにはどうすればよいですか?

最初は main メソッドで定義されたウィンドウです (これらは固定形式です。やり方がわからなくても大丈夫です。Ctrl c v だけで大丈夫です。データを見れば基本的に理解できます)

スーパー クラスを 1 つ記述します。スーパー クラスには、潜水艦、爆雷、機雷、戦艦の幅と高さ、出現時の X 座標と Y 座標、および移動速度が必要です。全オブジェクトの画像、全オブジェクトの移動方法、衝突

次に派生クラスを記述します。機雷潜水艦を倒すと戦艦はライフを1つ獲得し、他の潜水艦を倒すと戦艦はポイントを獲得します。したがって、定義する必要があります。 2 つのインターフェイス、1 つはライフの追加に使用され、もう 1 つはポイントの追加に使用されます。

完全なコードは次のとおりです (画像は自分で見つけることができ、Image クラスと幅を変更するだけです)
