Assignment4

(Note that this part is already done in the Assignment4.java file that is given to you. This explains each functionality of this class.)

In this assignment, download Assignment4.java file by clicking the link, and use it for your assignment. You do not need to modify Assignment4.java file. You only need to write Movie.java and Production.java files.

The following is the description of Assignment4 class.

The driver program will allow the user to interact with your other class modules. The purpose of this module is to handle all user input and screen output. The main method should start by displaying the following menu in this exact format:

Choice\t\tAction ------\t\t------ A\t\tAdd Movie D\t\tDisplay Movie Q\t\tQuit ?\t\tDisplay Help

Next, the following prompt should be displayed:

What action would you like to perform?

Read in the user input and execute the appropriate command. After the execution of each command, re-display the prompt. Commands should be accepted in both lowercase and uppercase.

Add Movie

Your program should display the following prompt:

Please enter the Movie information:: Enter its title:

Read in the user input and set the title on the movie object. Then it will ask a user to enter a movie length, its movie year, its production company's name, city, and state.
