Answer:

a. A class can be both a subclass and a superclass at the same time. b. Every class is a subclass of the object class. c. Common features should be located as high in the inheritance hierarchy as possible. d. The toString and equals methods are inherited by all classes. e. The type of the reference, not the type of the object, is used to determine which version of an override method is invoked.

Answer:

One of the fundamental ideas in object-oriented programming (OOP) languages is inheritance.

Explanation:

Inheritance in object-oriented programming:

• It is a mechanism that allows you to create a hierarchy of classes that share a set of properties and methods by deriving a class from another class.
• Inheritance is a technique to describe real-world relationships while OOP is all about real-world objects. Here's an illustration: a car, a bus, and a bicycle are all included in the larger category of "vehicle." That indicates that they have inherited the characteristics of the class of vehicles, i.e., they are all utilised for transportation.
• A process used to acquire a class's characteristics and behaviours by another class called inheritance.
• The class that inherits from the base class is referred to as the derived class, while the class that inherits from the base class is known as the parent class.
• The IS-A relationship is implemented by inheritance.

Thus, programmers can construct classes by building on existing classes and specifying a new implementation while keeping the same characteristics due to inheritance.
