for 循環一遍又一遍地重復

Question

這是我的程序中唯一不能正常工作的部分。 如果這個人選擇了一個 50 美元的座位，它會打印一個 0 來標記它已經售出。 如果不再有該價格的座位，則應打印出“抱歉，該座位不可用”。 它確實打印了那個，但它打印了 8 次。 （50 美元座位的數量）這是我的全部代碼。

這是輸出：

您的座位已被預訂。 您購買的座位上會顯示零。 您想預訂另一個座位嗎（是/否）？： y 按座位 s 或按價格選擇 p：（鍵入 Q 取消。） p 請輸入您想要的座位的價格：50 抱歉，該座位不可用. 抱歉，該座位不可用。 抱歉，該座位不可用。 抱歉，該座位不可用。 抱歉，該座位不可用。 抱歉，該座位不可用。 抱歉，該座位不可用。 抱歉，該座位不可用。 您想預訂另一個座位嗎（是/否）？：

Answer 1

問題出現在價格方法而不是數字上，如果用戶輸入50 ，則您正在檢查可用座位的矩陣seatsArray[][] ：

解決方案：您需要在預訂座位時添加一個boolean ，以便您可以將其設置為true並轉義for而不是if上的循環
