Inheritance & Polymorphism Programing Problem
Create a Vehicle class that is an abstract class defining the general details and actions associated with a vehicle. Create Car Truck and Minivan classes that inherit the Vehicle class. The Car Truck and Minivan classes should include additional members specific to the type of vehicle being represented. Create client code to test the classes.
Save the program as InheritanceFirstThreeLettersOfYourLastName in the Test#3 folder that you just created. If Nancy Smith were saving this program she would save it as InheritanceSMI.

- Design a GUI for Book view class for the following Library Information System, which you have worked on 1 with the following details: Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program that creates three instances/objects of the Library Items class. Extending Library Item Class (Library and Book Classes): Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program with an object of Book class.Objectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"
- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.Convert UML class diagrams to Java code You are required to convert the UML class diagrams shown below into Java code.

- Create a class Car which contains members speed, noOfGear. The class has a method drive( ) which is responsible to provide starting speed and noOfGears to a Car. Implement display( ) method which will display all attributes of Car class. The class SportCar is derived from the class Car which adds new features AirBallonType. When this method is invoked, initial speed and gear status must be displayed on console. Override the display method which display all attribute of the SportCar. Make use of super class display( ) method.Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age. Print the course information of c2 using getter methods I attached Typical run of the programA silos is a cylindrical like container used to hold grains in farms. Create class silos where each silos has three instance variables height, radius and color. The constructor creates a silos with all three variables. It has two instance functions calculateArea and calculateVolume. Create a test class that asks the user to input the height, radius, and color of the silos and then creates a silos using these input values. Then print all the information of the container height, radius, color, area, and volume. in java programming lnaguage

Write an application that demonstrates using objects of each classin netbeans Write a complete class named Crab that includes a String property named myColor and an int property named myAge. You must also include a default constructor that initializes myColor to RED and myAge to zero as well as an “other” constructor that accepts two parameters and uses them appropriately. You must also implement the getAge and setAge methods. Next Construct a Crab CB1 object using default constructor and invoke all accessible methods.
