publicvoidcallOverridedMethod() { super.fly();//fly()是父类中被覆盖的方法 } 注:super限定用于限定该对象调用它从父类继承的实例变量或者方法,但是super不能出现在static修饰的方法中,因为,static修饰的方法是属于类的,该方法的调用者可能是一个类,而不是一个对象,因此super限定也就失去了意义。?不明白什么...

Method的invoke方法 1.先检查 AccessibleObject的override属性是否为true。 AccessibleObject是Method,Field,Constructor的父类,override属性默认为false,可调用setAccessible方法改变,如果设置为true,则表示可以忽略访问权限的限制,直接调用。 2.如果不是ture,则要进行访问权限检测。用Reflection的quickCheckMemberAccess方法先检查...
