Concept explainers
In an inheritance relationship, the ___________ is the general class.
a. subclass
b. superclass
c. slave class
d. child class
In an inheritance relationship, the superclass is referred as “General class”.
Hence, the correct answer is option is “B”.
Explanation of Solution
Inheritance:
In python, it is possible to construct a new class that inherits the members of an existing class, which is referred as “inheritance”.
“is a” relationship in inheritance:
In python, if one object is a specialized kind of another object, then there should be an “is a” relationship between those objects. This is used to create the “is a” relationship among several classes.
For example:
- A truck is a vehicle.
- A circle is a shape.
Super class and sub class:
In python, the inheritance concept involves two classes. They are superclass and subclass.
- A superclass is also referred as “general class” or “base class” and a subclass is referred as “specialized class” or “derived class”.
- The sub class is an extended kind of the superclass. This means a subclass can inherit the attributes and class member functions from the superclass without rewriting them in the subclass.
- Extra methods can be added in the subclass, which implies the specialized kind of the superclass.
Explanation for the incorrect options:
In inheritance, a subclass is referred as “specialized class” or “derived class”.
Hence, option “A” is wrong.
In inheritance, slave class is not present.
Hence, option “C” is wrong.
In inheritance, a subclass is referred as “specialized class” or “derived class” or child class.
Hence, option “D” is wrong.

- True or False:Unlike other members of a superclass, constructors of a superclass are not inherited by its subclasses. This means that you must define a constructor for a class or use the default constructor added by the compiler.arrow_forward___________ is an Object-Oriented programming feature that allows you to define new classes from existing classes. 1 Overriding 2 Overloading 3 Inheritance 4 Polymorphismarrow_forwardIn single inheritance, a class exists in a(n)_____________ relationship with its derived classesarrow_forward

- Use JAVA - This task helps you understand how constructors work in inheritance Create a superclass, called SuperClass. Create a constructor for it. Inside the constructor, let it print “this is super class.” Create a childclass of SuperClass, called ChildClass. Create a constructor for it. Inside the constructor, let it print “this is child class.” Create a main function and create a new object for ChildClass. Observe what’s printed in console. What will happen if you have a default constructor without parameters in addition to the one with parameters?arrow_forwardCreate an Employee Class with the ff: attributes: = String name = double salary = String birthday = __init__(self, name, salary, birthday) = String getDetails() -- returns a String value that represents all the information of the Employee object Create a Manager class that inherits Employee, a Manager will also have the ff: = String department = __init__(self, name, salary, birthday, department) = String getDetails() -- returns a String value that represents all the information of the Manager object Create a Director class that inherits Manager, a Director will also have the ff: = double carAllowance = __init__(self, name, salary, birthday, department, carAllowance) = def playGolf() -- will print a string value '{name of director} plays golf' = String getDetails() -- returns a String value that represents all the information of the Director object Create 2 objects of each class and call their respective getDetails() method.
