在netbeans的第192行出现问题
似乎无法弄清楚问题是

Line 192: System.out.println("Percent off: "+customer.getcustomerDiscount());

Error:
cannot find symbol
symbol: method getcustomerDiscount()
location: variable customer of type Customer

(PS yes i know it's in 1 java file, it's supposed to be)

额外
我有点困惑，我给驱动程序1打电话，甚至做成了一个对象，可能使它工作。当我以其他方式测试if else语句时，又弹出了另一个问题

问题我应该将if else语句保留在setter中吗？或放入吸气剂？我认为我没有检索字符串是因为我将其全部设置为INT

最佳答案

您试图在getcustomerDiscount对象上调用Customer。该方法不是在此类上定义的，而是在Driver1上定义的。

另外：您应尝试使用Java命名约定，在这种情况下，应将getcustomerDiscount和setcustomerDiscount分别重命名为getCustomerDiscount和setCustomerDiscount。
