/**
 * It's designed to provide a convenient way to parameterize the generic type (e.g., {@code List.class}).
 * 

 * But the returned Class by all the methods doesn't have the actual parameterized type information. For example:
 *  * 
 * {@code Class> clazz = Clazz.ofList(String.class);}
 * // clazz doesn't have the actual type parameters information.
 * // you won't be able to get type parameter {@code String} by: cls.getTypeParameters();
 * // To save the real type parameters: you need to either:
 * {@code Type> type = Type.of("List"); // or Type.ofList(String.class)}
 *
 * // Or
 * Type<List<String>> type = new TypeReference<List<String>>() {}.type();
 *
