The `keySet` method returns a set of elements that implement the `Set` interface. You can use a for-each statement to go through a set that implements the `Set` interface. The hash values can be obtained from the hash table using the `values` method. The `values` method returns a set of elements that implement the `Collection` interface. Let's take a quidk look at the `Set` and `Collection` interfaces.
