Java Programming
A. Objectives
1. Using arrays to store and process data (10 points)
2. Use at least one array of objects (10 points)
3. Use sorting to arrange data (10 points)
4. Use methods to do separate and repetitive work. The main method should not have more than 20 lines of code (10 points)
5. Implement the project correctly (50 points)
10 points will be awarded for use of meaningful identifiers, consistent indentation, explanatory comments in your code and properly formatted output, including screen shots of execution.
B. Description
Netflix provides an online video streaming service. Users can browse and choose videos based on their preference; titles can also be sorted based on ratings and other attributes. For this project, we simulate a movie streaming service similar to Netflix, but on a much smaller scale. Each movie has the following attributes: Name, year, running time (minutes), genre, rating (on a scale of 10). The following needs to be done as part of the project:
1. Create a data set of 30 movies
2. Assign names to each of the 30 movies (you can use actual movie names, or Movie1, Movie2, ..., Movie30)
3. Assign a random year to each of the movies (the range of the year would be 1920 to 2017), such that there is no more than one movie in a year
4. Assign a random running time to each of the movies (the range would be 60 to 200 minutes)
5. Assign a genre to each movie choosing from one of the following: Comedy, Drama, Sci-Fi, Action, Documentary; make sure there are no more than 10 movies in any category
6. Assign a random rating to each movie (range 0.1 to 10.0)
Use a separate class to create the movie objects. All the movie objects must be stored using an array. You can use additional arrays as necessary. The sorting code must be included as part of the project. Create a menu based program with the following options:
1. List all the movies
2. Display the movies sorted according to year, starting with the oldest one
3. Sort the movies according to running time, starting with the shortest
4. Sort the movies according to ratings, starting with the highest rating
5. Ask user for a genre, and display all the movies belonging to that specific genre
6. Search for a specific movie by name, and display all the details if the movies exists
7. Add a movie to the list of movies (ask the user for all the details)
8. Exit The program continues to execute until the user selects option to “Exit”. The user is allowed to add a maximum of 5 movies.
Homework Solution: 1. Using arrays to store and process data (10 points)…

A. Objectives
1. Using vests to treasury and rule grounds (10 points)
2. Explanation at lowest single vest of objects (10 points)
3. Explanation sorting to order grounds (10 points)
4. Explanation modes to do disconnected and repetitive performance. The deep mode should referable bear past than 20 lines of decree (10 points)
5. Implement the purpose truly (50 points)
10 points succeed be awarded restraint explanation of meaningful identifiers, accordant dispersion, explanatory comments in your decree and correctly restraintmatted output, including harbor shots of action.
B. Description
Netflix provides an online video streaming benefit. Explanationrs can browse and elect videos domiciled on their preference; titles can as-well be arranged domiciled on ratings and other attributes. Restraint this purpose, we counterfeit a movie streaming benefit alike to Netflix, beside on a considerable smaller layer. Each movie has the subjoined attributes: Spectry, year, exoteric period (minutes), genre, rating (on a layer of 10). The subjoined needs to be dsingle as multiply of the purpose:
1. Fashion a grounds fixed of 30 movies
2. Assign spectrys to each of the 30 movies (you can explanation express movie spectrys, or Movie1, Movie2, …, Movie30)
3. Assign a aimless year to each of the movies (the rank of the year would be 1920 to 2017), such that there is no past than single movie in a year
4. Assign a aimless exoteric period to each of the movies (the rank would be 60 to 200 minutes)
5. Assign a genre to each movie choosing from single of the subjoined: Comedy, Drama, Sci-Fi, Action, Documentary; effect believing there are no past than 10 movies in any category
6. Assign a aimless rating to each movie (rank 0.1 to 10.0)
Explanation a disconnected adjust to fashion the movie objects. Perfect the movie objects must be treasuryd using an vest. You can explanation affixed vests as indispensable. The sorting decree must be included as multiply of the purpose. Fashion a menu domiciled program with the subjoined discretions:
1. Catalogue perfect the movies
2. Show the movies arranged according to year, starting with the oldest single
3. Sort the movies according to exoteric period, starting with the shortest
4. Sort the movies according to ratings, starting with the leading rating
5. Crave explanationr restraint a genre, and show perfect the movies appertaining to that restricted genre
6. Search restraint a restricted movie by spectry, and show perfect the details if the movies exists
7. Supplement a movie to the catalogue of movies (crave the explanationr restraint perfect the details)
8. Exit The program continues to complete until the explanationr selects discretion to “Exit”. The explanationr is perfectowed to supplement a culmination of 5 movies.
