Concept explainers
In an inheritance relationship, this is the general class.
- a. subclass
- b. superclass
- c. slave class
- d. child class
The general class in the inheritance relationship is “superclass”.
Hence, the correct answer is option “B”.
Explanation of Solution
Superclass:
- The superclass is the base class or a parent class which is used to derive a new class.
- The methods, functions and variables in the subclass are not used by the superclass.
- The keyword “extends” is used to define a subclass that extends a superclass.
- The superclass is the base class for all the classes, so in inheritance relationship, this is the “general” class.
Explanation for incorrect options:
a. subclass:
The subclass is the derived class from superclass, which means the subclass contains more information when compared with the superclass.
Hence, the option “A” is wrong.
c. Slave class:
There is no class called as “Slave” class in Java.
Hence, the option “C” is wrong.
d. Child class:
The derived class is sometimes called as child class in java.
Hence, the option “D” is wrong.

Because of single inheritance, the subclass can have no subclasses. b. Because of single inheritance, the subclass can have only one parent. c. Because of single inheritance, the subclass can have only one child classes. d. Because of single inheritance, the subclass can have no siblings.arrow_forward

- Draw a class diagram consisting of a base class named Person and a derived class named Student consist of : Encapsulation Polymorphism Inheritance Base classes vs Derived classes Protected Access vs Packaged Access & Abstract Methods and Classesarrow_forwardConsider the following scenario: A chicken, eagle and duck are birds. A dog, cat, cow,and lion are animals. Human and Birds are also animals. Peas, carrots, and grass areplants. Chicken, duck, cow, and plants are edible. Draw a class diagram for the abovescenario. You can use classes, inheritance, interfaces, and associations (includingcomposition or aggregation) when needed. You shouldn’t use operations.arrow_forwardA 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 understandarrow_forward
- Which of the following are not true about inheritance? (Multiple choice can be selected) A It is the pillar of the OOP paradigm that states that a class' variables and methods can be duplicated by its child classes by inheriting them. B It is done to avoid duplication of codes. C It is used to conceal the implementation of codes. D It is used to protect the integrity of data. E None of the other choices are correct.arrow_forwardThe method of the parent class can be re-used and modified in a subclass inherited from the parent class.
