- Object adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.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"
- Which Option is false about final classes Select one: A final class cannot be extended A final class cannot extend other classes A final method can be inherited A final method cannot be overridden in its subclasses1- A variable of class type (i.e., object) always require the same amount of memory to store its values? False True 2- A class that contains no methods (other than constructors) that change any of the data in its object is called as: Mutable class Immutable class Anonymous class Class invariantWhat is a static variable? Group of answer choices 1. None of the options are correct. 2. A variable that is common among all instances of the class, and can be accessed without any instantiation of the class. 3. Variables cannot be static, only methods can. 4. A variable whose value remains fixed after creation, and cannot change. 5. A variable that gets destroyed when the instance of the class is no longer used.
- A class can be instantiated from an object. True FalsePractice with writing a program that contains three classes: Ship CruiseShip CargoShip Classes Design a Ship class with the following members: A field for the name of the ship (a string) A field for the year that the ship was built (a string) A constructor that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship’s name and the year it was built Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class’s toString method should return a string with only the ship’s name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the…Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…
