### 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`:

        });

        TaskProvider<Javadoc> javadocAll = tasks.register("javadocAll", Javadoc.class, task -> {
            task.setGroup("documentation");
            task.setDescription("Generate Javadocs for all API classes");

            // TODO: This breaks if version is changed later
            task.setTitle("Gradle API " + project.getVersion());
