我想請問一下 這3個問題的差別?? 1. Which of the following are modifiers that can be applied to a field declaration within an interface? 2. Which of the following is a modifier that can be applied to a field declaration within an interface? 3. Which of the following modifiers can be applied to a class that is declared within an enclosing interface? 其中1,2只差在is跟are , 難道只是差單選跟複選嗎? 題目的問的內容應該是一樣的嗎? 3.enclosing interface??這是什麼意思阿?? 還有 1. Which of the following are modifiers that can be applied to an interface that is a member of a directly enclosing class? 2. Which of the following are modifiers that can be applied to an interface that is a member of a directly enclosing interface? 這兩個 我也有點搞不懂 directly enclosing class , directly enclosing interface 的差別?? --
