Homework 5

Details

Practice with ArrayList

• Add a playingTime field of type int to the Track class.
  • Update the setDetails method to include the playing time. This will introduce compiler errors until you do the next item.
  • Set playing time to a default value of 99 in the existing constructors.
  • Add a third constructor (with parameters including artist, title, and filename) that can set the playingTime to a different value.
  • Add an accessor method for playing time.
  • Update the getDetails method to include the playingTime.
• Add a method for the MusicOrganizer class named getTotalPlayingTime() with an int return type. It should add up and return all the values of playingTime for all the tracks stored in its ArrayList.
• Add a method for the MusicOrganizer class named get99MinuteTracks() that returns an ArrayList with all the tracks that have a 99 minute playing time.
