- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.Using JAVA An account record has the following:Account nameAccount surnameAccount numberAccount typeInterestBalance Create an AccountRecord class, complete with accessors and mutators (get and set methods) for theinstant variables as well as the toString method for formatting the object.The Account Record class must have an abstract method called calculateinterest A savings account must have a minimum balance of R500 and has an annual interest of 5%, If thebalance is greater than R10000 the annual interest is 7% and if the balance is greater than R50000 theannual interest is 8%An investment account must have a minimum balance of R100000 and the annual interest is 9%,Withdrawals cannot be made on an investment account.A check account can have a minimum balance of RO.

- This program is based in Java, so the response has to be java. Movie Collection Program Create a program that keeps track of your movie collection. Your driver file is movieCollection You will use it to create 4 movie objects. Your Movie class should have a default constructor that does not receive any values and sets all information to default values. You should also have an overload constructor method that has all of the data passed into it. The following information is what each movie object should have: Title Genre Year of release Director. You should have mutator methods that let you set all pieces of information individually. You should have accessor methods that allow you to get each piece of information individually. You should have a toString method that prints out all of the information about a movie at one time. Each piece of information should be on its own line. In the movieCollection file Movie one should be created using the default constructor.…PYTHON Write a class named Employee that holds the following data about an employee in attributes: name, ID number, department, and job title. Once you have written the class, write a program that creates three Employee objects to hold the following data, then save the data in (employee.txt) file• Write a class to maintain data about a single pizza. It should maintain information about its topping, size, and price. The class should have appropriate get and set methods. • Once you have the class written, it is time to write the program that will use the class. It needs to create 2 Pizza objects, set the data, and then print the data about each pizza. • Use the following values when creating your pizzas: o Pizza 1 Topping: Extra Cheese o Pizza 1 Diameter: 14 o Pizza 1 Price: 15.99 o Pizza 2 Topping: Pepperoni o Pizza 2 Diameter: 12 o Pizza 2 Price: 13.49 • Note that this program has no user input (no cin statements) Sample Run #1 (bold, underlined text is what the user types): Pizza 1 is a 14 inch pizza with Extra Cheese It will cost $15.99 Pizza 2 is a 12 inch pizza with Pepperoni It will cost $13.49
- Java Overview In this task, you will try to create a class called Course and a test class that creates objects of the Course class. The purpose is to teach you to write classes, create objects of classes and call public methods on the created object. Task Write a class that represents a course given here at San University. The class must contain information about the course course code, name, number of credits and a description. This should be stored as instance variables in the class. Use English names for all variables and methods. All instance variables must use the String class as the data type. The instance variables may only be accessible within the own class. It must be possible to set new values for all instance variables in the class. This must be implemented with public set methods for all instance variables. There should also be a method that prints all information about the course on the screen in a "nice" and structured way. You must also write a "test class" that…If we do not override the toString method in a class, the toString method for the Object is called. The default output is <class name>@<memory location>. True FalseThis is the default value for fields declared to "hold" object instances. Such indicates that the variable does not currently hold a reference to a valid object instance. *
- 2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.is a construct that defines objects of the same type. A class An object A method A data fieldComputer Science Write the code to define a class called student. The student class should contain a data attribute called name and another attribute called gpa. Write the Student class to include an initializer method __init__ and a __str__ method. Create two different objects of the student class and call print on each object to display the output in the __str__method.
