How is the song selected by the title variable?

Question

Java

How the song is selected by the tittle variable (should there be a selection condition)
What is the SoundPlayer Class

Answer 1

The program enters main, then creates an object, then passes String (song and artists) to setters, then, through the play method, looks for the title of the song, choosing from objects (if (entered track number 1) play t.2 else s.3)

Answer 2

The class is taken as an example. The choice of a song by name is implemented in the playSound() method, in which way it is not essential for this example.
