Chapter 9, Problem 1MC

In an inheritance relationship, this is the general class.

1. a. subclass
2. b. superclass
3. c. slave class
4. d. child class

Program Description Answer

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.
