Question
Congratulations, you have just become Java TV's newest owner! Java TV is the greatest TV channel ever, and it prides itself in its 24 hour interesting ' programming' . To help you run this channel you will need to write a dynamic program that uses Data Lists to store all its TV show information.
Your program will contain the following Menu Options:
1. Enter TV Shows/ Add a TV Show:
This option should allow the user to enter as many shows as he wants, your program should always keep track of how many shows the user has entered.
2. Modify TV Show:
This option should ask the user what show he would like to modify and search for it using the name of the show as the search key. The user should be able to modify that show information
3.Delete TV Show:
Like the Modify option, the delete option searches for a show using the show's name. Once found the show should be removed by shifting the array one space.
(Example: to delete array position 4, 5->4, 6->5,7->6...and so on)
4.Sort TV Shows:
The sort function asks the user what sort key he would like to use (name, day, time) and sorts the list using that key.
Note: The sort by day will sort alphabetically, that is fine,
see the Bonus for a proper day sort
5.Show all TV Shows:
This option outputs all the shows and also gives totals for the number of shows per day.
6.Exit: This will quit the program
***IMPORTANT: I ONLY use java 1.4.2. I cannot use newer versions, therefore classes such as scanner dont work. please make sure it works with 1.4.2. Thank you. Lifesaver Ratings
Explanation / Answer
Save the file as TVShow.java. Compile and Test it. Let me know, in case of any errors or issues. I can fix it.
