(9) Write a java program to implement an inventory system for the video rental store. A video store consists of many videos. Each video consists of a title and a status of whether the video is rented out or not. There should be a method to track whether the video is rented or returned.
The video store will provide the facility to add a new video (by title) to the inventory, check out a video (by title), return a video to the store, and list the whole inventory of videos in the store. Create a main class VideoStoreLauncher with a method which will test the functionality. The videos can be added in bulk by specifying the number of videos first then followed by their titles.
Sample input and output
1.Add video
2.Check availability 3.Rent a video
4.Retum
5.List the inventory 6.Exit
