このプログラムは、テストが参照内にあるか、テストが参照をオーバーラップしているかを確認するために、参照矩形とテスト矩形の2つの矩形を比較することを想定しています彼らは境界を共有しているか、またはそれらが区別されています。Java入れ子Do-Whileループ
私のプログラムは最初に基準矩形を読み、次にテスト矩形を読み込む必要がありますが、プログラムが完了した後、ユーザはプログラム全体を繰り返すか新しい基準矩形を入力するか、そこでテスト矩形に入る。
2回目のtesting whileループを取り囲む大きな参照whileループを作成し、異なるrepeatInt変数を作成しました。ユーザーが2を入力したときにプログラムがテスト矩形の入力部分で正しく再開するため、問題がどこにあるかはわかりませんが、1になるとテスト入力部分でプログラムが再び開始され、もう一度プログラム全体を実行してください。
はここに私のコードです：
