Map each of the keywords on the left to the statement that describes it the best. Inheritance Class Object Polymophism Instance variable [Choose ] ✓ It is any variable that does not represent a living being. It allows properties and functions to be passed to another object when an object is deleted. It represents a blue print of an object. It is like a global variable that can be accessed in all functions of a program. It is a category to organize variables and objects in groups. It is an instance of a class. It is a programming command with a special meaning. Classes can acquire properties and functions from other classes. It is a property inside that class that exists throughout the lifetime of an object. It is used to define the relationship between classes. It is a variable of a primitive type. It is a variable that can store values of multiple types. It allows a variable of a super class type to be assigned an instance of a subclass type. It is used to describe that a class…
A base class is. A class that is at the bottom of the inheritance hierarchy. A class that has more than one class derived from it. A class that inherits from another class A class that is inherited by another class, and thus is included in that class. O O O O
5.The design for class and inheritance 1. Inheritance progrmming (1).Create class Point, with two private instance variables x and y that representd for the coodinates of a point. Provide constructor for initializing two instance variables. Provide set and get methods for each instance variable, Provide toString method to return formatted string for a point coodinates. (2). Create class Circle,it inheritance from Point. Provide a integer private redius instance variable. Provide constructor to initialize the center coodinates and redius for a circle,.In the constructor it must calls its supperclass constructor by using super(x,y); Provide set and get for redius instance variable. Provide two methods for calculating its area and perimeter. Provide toString method to return a formatted string for a circle features.In the method, it must calls its supperclass toString method by using super.toString(). (3)Similar to the above class Circle definitionto,Design Rectangle…
Multiple inheritance can be explained as all choices are wrong one class inheriting from more super classes more classes inheriting from more super classes one class inheriting from more super classes and more classes inheriting from one super class more classes inheriting from one super class
Create a class hierarchy for base class Shape and derived classes Triangle, Rectangle, Circle and Square Demonstrate concepts of abstraction, overriding, polymorphism and static field May use methods such as 'calculateArea()', 'calculatePerimeter()', etc. as needed for demonstrating concepts May use static field to represent color of the class or name of the class to represent concept of static fields
Asiacell I. docs.google.com 1 point A variable that is declared is visible in the class it is declared in, and all of its subclasses. Your answer 1 point Inheritance provides, which allows a derived class to inherit from many base classes. Your answer 1 point When an object of a derived class is instantiated, the base class' Lis called implicitly or explicitly to initialize the- data members of the base-class in the derived-class object.
С++ Multiple inheritance is When a class is derived from another class When a class is derived from other two derived classes When a class is derived from two or more classes When a class is derived from exactly one class
Class Relationships Exercises 1. In Java, we use inheritance for "is-a" relationships. Containment, on the other hand, indicates that one object has another object. These are "has-a" relationships. For the following relationships, determine if they are a "is-a" or a "has-a" relationship: o bicycle - vehicle o car - engine o pizza - topping o food - pizza o dog - mammal 2. Share with someone else 3 other examples for each of the following relationships: o Inheritance ("is-a" relationship) o Containment ("has-a" relationship) 3. public class PersonInfo { protected String firstName; protected String birthdate; } public class ChildInfo extends PersonInfo { private String schoolName; } public class MotherInfo extends PersonInfo { private String spousename; private ChildInfo children1; private ChildInfo children2; private ChildInfo children3; ... } A. Draw the relationships for the classes above using UML. If a class inherits from another class, draw an open arrow pointing to the base class…
Class Inheritance with abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as: name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the employee works…
How can we restrict inheritance for a class so that no class can be inherited from it?
1) Implement converter class hierarchy as follows:a. Converter class which includes: Private attribute for input of data type double Default constructor with no parameter which sets input to Double.NaN Overloaded constructor with input for parameter Get and set methods for input attribute Method convert() which returns input valueb. TemperatureConverter class which is a child of Converter and includes: Constructors which call parent constructors Overridden convert() method to convert input (Fahrenheit temperature) toCelsius and returns the value. If the instance has no input value, it shouldreturn Double.NaN Use the following formula for conversion: C = ((F-32)*5)/9c. DistanceConverter class which is a child of Converter and includes: Constructors which call parent constructors Overridden convert() method to convert input (distance in miles) to distancein kilometers and returns the value. If the instance has no input value, itshould return Double.NaNd. Use the following…
A high value of Depth of Inheritance Tree (DIET) for a class indicates that? The class reusability is high The class is easy to test The class is easy to maintain The class is easy to understand
