Get scala's case class parameters using java reflection API
Get scala's case class parameters using java reflection API
I need to get the member variables/parameters of scala case class in java. I tried using the java reflection API in the usual way but doesn't work with scala class.
List<Field> fields = getPrivateFields(myClass.class);
where myClass is a scala case class. How do I achieve this in java?
myClass
public static List<Field> getPrivateFields(Class<?> theClass){
List<Field> privateFields = new ArrayList<Field>();
Field fields = theClass.getDeclaredFields();
for(Field field:fields){
if(Modifier.isPrivate(field.getModifiers())){
privateFields.add(field);
}
}
return privateFields;
}
getPrivateFields
Added getPrivateFields method. Also, I referred that code from one of the stackoverflow answers.

And what is the problem? Do you get an empty list? Show your case class and the output of your program and state what you expected instead.
