Java Question - Using the bottom code, create another class named "DigitalBook" as a subclass of the given "Book" class. Then, Make sure that the "DigitalBook" class contains two constructors: (1) one is the default constructor that takes no parameter, and (2) the other is a parameterized constructor that take 6 parameters. Be sure to use the “super” keyword in the constructors of the "DigitalBook" class. In the “main()” method of the “EX12_1” class, create four instances: “b1”, “b2”, d1”, and “d2”. Let “b1” and “b2” be the instances of the “Book” class, and let the “d1” and “d2” be the instance of the “DigitalBook” class. Be sure to use the specified constructor (as shown in attached picture) to initialize these instances. The Final Output is shown in the attached pictures. Please make sure that no errors show up in the Java Compiler when testing the code. Thank you.

QI. Write a program in BlueJ using the following hints. 1. Create a class named Book and declare the fields author, title and pages with suitable field types. 2. Declare the constructor and initialize the fields author and title with the assigned constructor parameter. 3. Name the constructor parameter as your own. 4. Add two accessor methods to the class getAuthor, getTitle and getPages—that return the author and title fields as their respective results. Add mutator method to change the pages of the Book class. 5. Add two methods, printAuthor and printTitle, to this Book class project. These should print the author and title fields, respectively, to the terminal window.
In Java, Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed.Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.)
Got stuck on this for my daily coding practice. I would like to understand it in Java. Given main(), complete the FoodItem class (in file FoodItem.java) with constructors to initialize each food item. The default constructor should initialize the name to "Water" and all other fields to 0.0. The second constructor should have four parameters (food name, grams of fat, grams of carbohydrates, and grams of protein) and should assign each private field with the appropriate parameter value. Ex: If the input is: Water the output is: Nutritional information per serving of Water: Fat: 0.00 g Carbohydrates: 0.00 g Protein: 0.00 g Number of calories for 1.00 serving(s): 0.00 Ex: If the input is: M&M's 10.0 34.0 2.0 3.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 3.0 is the number of servings, the output is: Nutritional information per serving of M&M's: Fat: 10.00 g Carbohydrates: 34.00 g Protein: 2.00…

create a Java Project (with a class and a test class) to represent some real-world entity such as city . The class will:a) Create a total of 5 member variables for the class by selecting the appropriate data typesfor each field. For example, a class to represent a lamp might include color, price, height,numBulbs, batteryOperated. Each of these 5 variables needs a data type.b) Include at least three different constructor methods, including the default constructor(no argument constructor), so totally three constructors.c) Create a method called showValues( ) to display the values of an object in a formattedmanner.The Java test class (with a main method) will:a) Instantiate at least three objects (using each of the constructors at least once) with yourprogram.b) Store the data from the individual objects into an array.c) Utilize the showValues() method to display the content of an object created.Note:1) Draw the UML diagram for the class and then implement the class.

You are designing an application to rate your professors.a. Professors have the following properties: first name, last name, universityname, subject, and ratings for overall quality (1.0-5.0) and level of difficulty(1.0-5.0). Your class should have instance variables of the appropriatetype for each property.b. Your class should have two constructors: one that takes all properties, andone that takes only first name, last name, university name, and subjectand sets both of the ratings to an appropriate default value.c. You should provide accessors (getters) and mutators (setters) for firstname, last name, university name, and subject.d. Your class should provide a method to add a new rating for the professor.It should take two arguments: one for overall rating and one for level ofdifficulty, with values from 1 (awful) to 5 (awesome). Each time a newrating is provided, your class should calculate the average rating for theprofessor and update the appropriate variable for each.e. Your class…

Please complete the following tasks: Write a class “Actor” that contains two attributes with the appropriate level of visibility explicitly defined. “Name” which is a String, Private, “NumberofAwards” which is an integer, private Write a default Constructor for this class that initializes the name to “Bob Smith” , and the number of awards to 0. Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.
Please written by computer source 1. Model a real-life object as a Java class with at least one attribute and an instance method. Write a main method to create an instance of the class, assign a value to the attribute, call your method, and demonstrate that the value of the attribute changed and that the method successfully completed what it was supposed to do. The main method can be created in a separate driver class (e.g. MyDriver.java) within which you will create an instance of the object class. For example, if the name of the object class is Car (meaning, you are coding Car.java) then you can create an instance of Car inside MyDriver.java.
