class Clazz{
public enum MyEnum{
Hello, World
}
}
With class Clazz, how do I get MyEnum.values() ?
An example of the usage is :
Class unknownClass = getSomeClass();
How to get MyEnum.values() from unknownClass?

Hint: inner enums are implicitly static. – Pshemo Dec 27 '15 at 03:49

2What have you tried? We need to know what you've tried and what's not working – Keith M Dec 27 '15 at 03:50

I was not looking for that. I am sorry that the question is vague, but I really want a reflection type answer. With just the Class Object – theAnonymous Dec 27 '15 at 03:50

Please [edit] your question and add more details about what you want to achieve. Also tag it properly (`reflection` tag could be nice if you need your solution to use it). – Pshemo Dec 27 '15 at 03:52

Are you asking how to find all nested subclasses using Reflection? – SLaks Dec 27 '15 at 03:55

You can do Clazz.MyEnum.values() to access the Enum or you can directly import MyEnum in your other classes import com.in.Clazz.MyEnum becuase MyEnum is public.
To get MyEnum constant via reflection, but if MyEnum is accessible then there is no need to use reflection. You can do it in following way,
Class<?> clazz = Clazz.class;//You are getting dynamically
Class<?> enumClass = clazz.getDeclaredClasses()[0];//assuming at index 0
Enum<?>[] enumConstants = (Enum<?>[]) enumClass.getEnumConstants();
System.out.println(enumConstants[0]);
OUTPUT

Method method = parameterIDClass.getMethod("values");
Enum<?>[] enums = (Enum<?>[])method.invoke(null);
