使用反射獲取接口或抽象類的所有方法

Question

如何在接口/抽象類上使用反射來獲取其所有方法？

Answer 1

例如，

MyInterfaceOrAbstractClass.class.getDeclaredMethods(); 

Answer 2

Class clazz = Something.class; 
Method[] methods = clazz.getDeclaredMethods(); 
for (Method method : methods) { 
    // do what you have to do with the method 
    System.out.println(method.getName()); 
}
