獲取父類的Class：

* Class getSuperclass()
* Object的父類是null
* interface的父類是null

![](http://blog.liufei1988.com/1a6585c1ce2bae1f47e08f311defb660)

獲取當前類直接實現的interface：

* Class[] getInterfaces()
* 不包括間接實現的interface
* 沒有interface的class返回空數組
* interface返回繼承的interface

![](http://blog.liufei1988.com/599c077337cb597b588d9a26e8f5e204)

判斷一個向上轉型是否成立：

* bool isAssignableFrom(Class)
