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.

- Inheritance is an OOP concept such that a class can be defined in different ways, such as either being typecasted to itself (as a subclass) or any of its superclasses.
