/*
* 目前看不出 Factory Method Pattern 的好處在哪，
* 因為沒有了 Simple Factory Pattern 把邏輯判斷給包裝起來，
* 但好像有 Strategy Pattern 的切換性，只要加上條件判斷就可以切換了，
* 因為已經有 Operation 這個父類別，但具體差異在哪還說不出來
* [實際上 Strategy Pattern 對於使用者來說會更方便，
* 因為使用者之需要用context class 去進行宣告(new出底層的物件給context)與操作]
* 而回過頭看， Simple Factory Pattern 每次新增條件都必須在內部的判斷式中加入新的case判斷條件，
* 會違反開放閉合原則，所以才會有 Factory Method Pattern 的出現
* 往後有新增新的類別，只需要做出對應的Factory Class，
* 並改動 IFactory operFactory = new AddFactory(); 這行的new就可以改變了。
