这个机制允许程序在运行时透过Reflection APIs取得任何一个已知名称的class的内部信息,包括其modifiers(诸如public, static 等等)、superclass(例如Object)、实现之interfaces(例如Cloneable),也包括fields和methods的所有信息,并可于运行时改变fields内容或唤起methods。本文借由实例,大面积示范Reflection APIs。

We can get Class of an object using three methods - through static variableclass, usinggetClass()method of object andjava.lang.Class.forName(String fullyClassifiedClassName). For primitive types and arrays, we can use static variableclass. Wrapper classes provide another static variableTYPEto get ...
