Can you provide Java class code for the requirement below

Observer Pattern

We want to have notifications that can be sent to the Console to simulate an external Event Logging System that may be used for Analytics and Live Monitoring.

$1.$ Implement Observer pattern being the Recording class, the Observable Subject, and a new Notifier class, the Observer.

$2.$ The event should be triggered when the Recording is updated with the transcript $($or result from the closed captioning process$)$ and the message generated should include information from the recording itself.

$3.$ Update the Main class accordingly.
