#### Generic types { #generic-types }

These types that take type parameters in square brackets are called **Generic types** or **Generics**, for example:

//// tab | Python 3.10+

You can use the same builtin types as generics (with square brackets and types inside):

* `list`
* `tuple`
* `set`
* `dict`

And the same as with previous Python versions, from the `typing` module:

* `Union`
* `Optional`

```

### Running
```bash
# From IDE: Run main method in org.codelibs.fess.FessBoot
# Access at: http://localhost:8080/
# Admin UI: http://localhost:8080/admin/ (admin/admin)

# From command line (after building)
./bin/fess
```

### Code Formatting
```bash
# Format code
mvn formatter:format

# Add license headers
mvn license:format
```
