- When the contents of an object cannot be changed after it is created, the object is referred to as mutable.object that is abstract a variable object Encapsulation1- 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 invariantpython code: 1.Create an empty class called Car. 2.Create a method called initialize in the class, which takes a name as input and saves it as a data attribute. 3.Create an instance of the class, and save it in a variable called car. 4.Call the initialize method with the string “Ford".
- True or False ___(37) If class B is a child class of class A, when you create an object from class B, both the constructor of class B and the constructor from the class A are used to create the object. ___(38) An Interface can have a method that contains an empty method body. ___(39) An object can have another object as its private variable.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 group or collection of objects with common properties is called: a. Class b. Interface c. Method d. Attributes
- True of False. When comparing two objects using the equals method inherited from the Object class, what is actually compared is the contents of the objects. Group of answer choices True FalseA class can be instantiated from an object. True FalseObject adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.
- True or False: Object privileges allow you to add and drop usersObjectives: 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…is a construct that defines objects of the same type. A class An object A method A data field
