java - Reflection: Constant variables within a class loaded via reflection

I have a class which has a bunch of Constant Strings.

I need to load this class via reflection and retrieve those constants. I can get up to:

controllerClass = Class.forName(constantsClassName);
Object someclass = controllerClass.newInstance();

but I am confused on how to retrieve the fields in this class.

See Question&Answers more detail:os

A quick sample on accessing fields --

Field[] fields = controllerClass.getDeclaredFields();

for ( Field field : fields ) {
   field.setAccessible(true);
  System.out.println(field.get(someClass));

}
