a. Radio station KJAVA wants a class to keep track of recordings it plays. Create a class named Recording that contains fields to hold methods for setting and getting a Recording’s title, artist, and playing time in seconds. Save the file as  Recording.java.

b. Write an application that instantiates five Recording objects and prompts the user for values for the data fields. Then prompt the user to enter which field the Recordings should be sorted by—song title, artist, or playing time. Perform the requested sort procedure, and display the Recording objects. Save the file as RecordingSort.java.
