Even robotic programmers yearn for art! Today we're talking about bowed string instruments. We have a Violin class. You need to change it to make it a task for a thread. To do this, use the MusicalInstrument interface. And then you can "play" it and display how long you've been playing.

You can't complete this task, because you're not signed in.

why does it specifically want us to use the date object being returned from the startPlaying and stopPlaying objects? Can't we use any other function like currentTimeMillis for this?
