Tasks

• Task 1

  Design and implement MusicStore as a public class with one public method, displayHoursOfOperation(). This method displays the daily hours of operation to the standard output device (often called stdout or standard out), which is either a command window or an IDE window, depending on your Java environment.

  Check the expected output to determine exactly what to print out.

• Task 2

  Design and implement TestMusicStore as a public class with one public static void method main(). main() performs the following tasks:

  • Creates an instance of MusicStore
  • Invokes the displayHoursOfOperation() method to display the daily hours of operation to standard output
  • Terminates the program with exit()

• Task 3

  Compile the source code for MusicStore and TestMusicStore.

• Task 4

  Execute TestMusicStore.
