These include: * Calling the instance method of a null object. * Accessing or modifying the field of a null object. * Taking the length of null as if it were an array. * Accessing or modifying the slots of null as if it were an array. * Throwing null as if it were a Throwable value. 五種情形我這笨蛋都幹過，還真猜不出你是指哪種錯誤 +_+ -- -- 嘿嘿..我是huge.. --
