试用Java中的反射reflect之getDeclaredMethods和getMethods
目的:根据类名、方法名以及方法对应的参数,获取方法,并实现方法的调用1、getDeclaredMethods和getMethods的区别
Method | getDeclaredMethod(String name, Class... parameterTypes) Returns a Methodobject that reflects the specified declared method of the class or interface represented by this Classobject. |
Method[] | getDeclaredMethods() Returns an array of Methodobjects reflecting all the methods declared by the class or interface represented by this Classobject. |
Method | getMethod(String name, Class... parameterTypes) Returns a Methodobject that reflects the specified public member method of the class or interface represented by this Classobject. |
Method[] | getMethods() Returns an array containing Methodobjects reflecting all the public member methods of the class or interface represented by this Classobject, including those declared by the class or interface and those inherited from superclasses and superinterfaces. |
