実際には、sourceno、destinationno、ttl などのユーザーからの入力を取得するスイング パネルを作成し、そのデータに基づいて、純粋にランダムな伝播アルゴリズム (PRP) を適用して、ネットワーク内を通過するルーティング ノードを見つけます。以下のコード (PRP.java) は、swing パネルで送信ボタンを押すと、コマンド プロンプトでトラバースされたルーティング ノードを出力します。
送信ボタンを押すと、結果の通過ルートがコマンドプロンプトではなく、送信ボタンの下の同じパネルのテキストボックスに出力されるように、コードを変更する必要があります
変更されたコードを提案してください.....
