### Classes como tipos { #classes-as-types }

Você também pode declarar uma classe como o tipo de uma variável.

Digamos que você tenha uma classe `Person`, com um nome:

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}

Então você pode declarar que uma variável é do tipo `Person`:

import org.codelibs.fess.util.ComponentUtil;
import org.dbflute.cbean.result.ListResultBean;
