JAVA
You are the software developer put in charge of helping an online streaming website to categorize its film collection. The company already has an existing collection of American films, but it wants to branch out into foreign films. While the company plans to have foreign films from many countries it plans to especially expand into Bollywood films. These films are from India and are primarily in Hindi, but they sometimes also have other secondary languages that are spoken in the films. Most Bollywood films are also musicals.
Once you take a look at their software you realize that they have not used object-oriented programming. The software they have is very difficult to reuse and update. You decide that you will have to create a new design for the software and start completely from scratch.
The development of this project must be done using object-oriented programming. All films should contain name of the film, name of the director, and year of release. All foreign films are films but also have language the film is in, subtitle information, and translation of the film name into English. There can be more than one subtitle for a movie (imagine a film in French that has English and Spanish subtitles). There can also be more than one director of a film. Bollywood films are foreign films that have songs and may have secondary languages as well.
There should ways to access and mutate all the information stored. Inheritance must be used to accomplish this assignment. There should be a parent class for films and a class which inherits from that class and represents foreign films and class that represents Bollywood films which inherits from foreign films.
In addition to the requirements above, each film class must override the toString method inherited from the Object class. The overridden definition of each toString method should return all the information stored about that specific film. The parent class for films must also override the equals method inherited from the Object class. This method should determine whether two films are the same. If they are the same it should return true otherwise return false.
Finally, demonstrate a prototype of this program by allowing the user to either create up to ten films (an array of films). Provide the user with a menu of options to create a film, foreign film, or Bollywood film. Once a film is created it should be stored so that it can be accessed
again. There should be an option to display all the information for all films entered so far. Use the toString method to display the information for each film. After a user enters a film use the equals method in the film class to make sure that film has not already been entered into the system. If it has tell the user that film already exists in the system and do not store it again. If it has not been entered then insert it into the system.
You may use any films to test your system, but make sure to include at least one film, one foreign film, and one Bollywood film, and at least five films. If you are not familiar with films or foreign films or Bollywood films a list is provided below so that you use these films to test your program.
