Methods

invoke(Object obj, Object... args)

• 作用：执行方法
• 注意：这个方法是 Method 类的方法

Person person = new Person("Tom", 18);
Class<Person> clazz = Person.class;
Method method = clazz.getMethod("show");

method.invoke(person); // name=Tom, age=18

通过反射执行私有方法

Person person = new Person("Tom", 18);
Class<Person> clazz = Person.class;
Method method = clazz.getDeclaredMethod("getInfo", String.class);

method.setAccessible(true);
Object result = method.invoke(person, "info:");

System.out.println(result); // info:Tom-18
