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

You can also declare a class as the type of a variable.

Let's say you have a class `Person`, with a name:

{* ../../docs_src/python_types/tutorial010_py39.py hl[1:3] *}

Then you can declare a variable to be of type `Person`:

{* ../../docs_src/python_types/tutorial010_py39.py hl[6] *}

And then, again, you get all the editor support:

    private final Throwable[] throwables;

    /**
     * Creates a new MultipleCrawlingAccessException with the specified detail message and array of throwables.
     *
     * @param message the detail message explaining the reason for the exception
     * @param throwables the array of throwables that caused this exception
     */
    public MultipleCrawlingAccessException(final String message, final Throwable[] throwables) {
        super(message);

### 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_py39.py hl[1:3] *}

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

{* ../../docs_src/python_types/tutorial010_py39.py hl[6] *}

E então, novamente, você recebe todo o apoio do editor:

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

También puedes declarar una clase como el tipo de una variable.

Digamos que tienes una clase `Person`, con un nombre:

Luego puedes declarar una variable para que sea de tipo `Person`:

{* ../../docs_src/python_types/tutorial010_py39.py hl[6] *}

Y luego, nuevamente, obtienes todo el soporte del editor:

   * this is subject to change. Also, {@code junit4.TearDownTestCase} will.
   *
   * @throws Exception for any reason. {@code TearDownTestCase} ensures that any exception thrown
   *     will not interfere with other TearDown operations.
