Answer 1

You can create a utility class to check if the class represents any Collection, Map or Array

  public static boolean isCollection(Class rawPropertyType) {
        return Collection.class.isAssignableFrom(rawPropertyType) || 
               Map.class.isAssignableFrom(rawPropertyType) || 
               rawPropertyType.isArray();
 }
