please anser the practice assgnment questions in th images attached. please leave your answer in C++ code ONLY You have been commissioned to develop a program to digitally record a rare collection ofLaserDisc movies. You will start by creating a LaserDisc class. It should have the followingprivate attributes:String movieTitleint releaseYear• String genrefloat ratingYour class should also have the following methods:Default Constructor: Initializes the four attributes to the following default values:o movieTitle = "Star Wars Holiday Special"releaseYear = 1978genre = "Science Fiction"o rating = 5.0%3D%3DOverloaded Constructor: Initializes the four attributes based on values passed into theformal parametersoIf rating is less than 0.0 or greater than 5.0, set it equal to 0.0If releaseYear is less than 1978, set it equal to 1978bool/Boolean isItGood(): Returns "true" if rating is 3.0 or greater, and "false" otherwise.Getter method for all class attributes You will then create a separate class, Assignment8A. In its main method, you should do thefollowing:Ask the user how many movies are in their collectionCreate an array (of type LaserDisc) of that sizeUse a loop to ask the user to enter information for all movieCreate a LaserDisc object for each movie and store it in the next index in thearrayThen using another loop, you should give the user the following options:Print movie informationThis should ask the user for a number, and then print the information from theLaserDisc object at that index. If the index is out of bounds, it should notify the userinstead.Recommend a good movie from the collectionThis should choose a random movie, check if it is a good movie based on the relevantfunction, and either print the information to the user or guess again if it was not agood movies If there are no good movies in the collection, tell the user that no goodmovies exist in the collection.Hint: You can use a counter variable to keep track of the guesses. When you'veguessed more times than numbers of elements in the array, you can stop. However,this means you might miss some movies if the same index is randomly selectedmultiple times. If you want to challenge yourself further, consider another way youcould handle that situation.

Actually, Java is a general-purpose also class-based, object-oriented programming language designed for having lesser implementation dependencies. It is a kind of computing platform for application development. It is fast, secure, and reliable, therefore.Here is the completed code for this problem. PROGRAM/CODE : - LaserDics.java class LaserDics { // Private members private final String movieTitle; private final int releaseYear; private final String genre; private final float rating; // Default Constructor. public LaserDics() { movieTitle = "Star Wars Holiday Special"; releaseYear = 1978; genre = "Science Fiction"; rating = 5; } // Overloaded Constructor public LaserDics(String title, int releaseYear, String genre, float rating) { this.movieTitle = title; this.genre = genre; // If rating is less than 0.0 or greater than 5.0, set it equal to 0.0 if(rating < 0 || rating > 5) { this.rating = 0; } else{ this.rating = rating; } // If releaseYear is less than 1978, set it equal to 1978 this.releaseYear = Math.max(releaseYear, 1978); } // Returns "true" if rating is 3.0 or greater, and "false" otherwise boolean isGood() { return this.rating >= 3.0; } // Getter method for all class attributes public String getMovieTitle() { return this.movieTitle; } public String getGenre() { return this.genre; } public int getReleaseYear() { return this.releaseYear; } public float getRating() { return this.rating; } } Assignment8A.java import java.util.Random; import java.util.Scanner; public class Assignment8A { public static void main(String[] args) { Scanner userInput = new Scanner(System.in); System.out.println("[Laser Dics Collection]"); // Ask the user how many movies are in their collection System.out.print("How many movies do you have? "); int totalMovie = userInput.nextInt(); // Create an array (of type LaserDisc) of user input size LaserDics[] discs = new LaserDics[totalMovie]; // variables String movieTitle, genre; float rating; int releaseYear; // loop to ask the user to enter information for all movie for(int i = 1; i <= totalMovie; i++) { System.out.printf("\nMovie %d:\n", i); userInput.nextLine(); System.out.print("*Enter Title: "); movieTitle = userInput.nextLine(); System.out.print("*Enter Genre: "); genre = userInput.nextLine(); System.out.print("*Enter Release Year: "); releaseYear = userInput.nextInt(); System.out.print("*Enter Rating: "); rating = userInput.nextFloat(); // Create a LaserDisc object for each movie and store it in the next index in the array discs[i-1] = new LaserDics(movieTitle, releaseYear, genre, rating); } int userChoice; // while Loop while(true) { // menu System.out.println(); System.out.println("[Main Menu]"); System.out.println("1) Movie Info"); System.out.println("2) Recommend a Good Movie"); System.out.println("3) Log Off"); System.out.print("Choice: "); userChoice = userInput.nextInt(); if(userChoice == 1) { System.out.print("\nWhich Movie do you want ?

For this lab, you will be doing the following in C#: 1) Create a Home form with buttons that when clicked, will open the Account, Email, and eventually the Contact forms. The Account form should be opened in "View" mode. 2) Add code to the Login form so the Account form opens when the user clicks "Create New Account". The Account form should be opened in "Modify" mode. 3) Add code to the Login form that validates the user input before allowing the user the access the Home form. For now, just verify the user enters "user1" and "12345" for the username and password respectively.
