だから私はJavaでかなり新しいので、接続4ゲームを作成する割り当てがあります。このような文字でいっぱいの6行7列のボードを作成します->「-」、ユーザーが希望の列を入力すると、「-」がBまたはR（赤または黒のチェッカー）に置き換えられます。背景。対角線をチェックするためのコードが非常に長い部分を除いて、すべてが機能します。異なる for ループでそれぞれを実行することを除いて、プレーヤーが勝つことができる可能な 4 セットの対角線すべてを通過する方法がわかりませんでした。 ..私はあなたがそれを短くするのを手伝ってくれるという恐ろしい希望を知っています:(
これが斜めチェックのコードです（笑 見てるだけで悲しくなります）
