 Once the topology is defined within the builder, the `buildTopology` function returns an instance of the `Topology` created from `builder.build`. Separating the building of the `Topology` in a function is useful for testing purposes, which we will see in the **Test It** section of the tutorial.

 Now create a utility class that provides functions to support our tutorial. You may decide not to include these types of functions in the production version of your application, however, they are useful for getting started quickly. This utility class includes functions to create our Kafka topics and generate sample event data we can use to exercise our Kafka Streams topology.
