a. Radio station JAVA wants a class to keep track of recording 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.
Write an application that stores at least four different course names and meeting days and times in a two-dimensional array. Allow the user to enter a course name (such as "CIS 110"), and display the day of the week and time that the course is held (such as "Th 3:30"). If the course does not exist, display an error message. Save the file as Schedule.java.
Create an application that contains an enumeration that represents the days of the week. Display a list of the days, then prompt the user for a day. Display business hours for the chosen day. Assume that the business is open from 11 to 5 on Sunday, 9 to 9 on weekdays, and 10 to 6 on Saturday. Save the file as DayOfWeek.java.
