How are classes derived from more than one base class?
Multiple Base Classes. A class can be derived from more than one base class. In a multiple-inheritance model (where classes are derived from more than one base class), the base classes are specified using the base-list grammar element.
A single copy of its data members is shared by all the base classes that use it as a virtual base. When declaring a virtual base class, the virtual keyword appears in the base lists of the derived classes. Consider the class hierarchy in the following figure, which illustrates a simulated lunch line.
How to create subclasses of a given class?
We can create subclasses of a given class that will inherit all of the instance variables and methods of the given class (called the super class) using the keyword extends. An example can be seen in the classes defined below. Here’s the output: In general: Subclasses inherit all instance variables and methods from their superclass
What happens when a part declares a base class?
If any part declares a base type, then the whole type inherits that class. All the parts that specify a base class must agree, but parts that omit a base class still inherit the base type. Parts can specify different base interfaces, and the final type implements all the interfaces listed by all the partial declarations.
How to create a book class in Java?
Allow the user to enter as many book objects as s/he wants. Take care of necessary object initializations. Store the first and last book objects separately. Print each book object. Compare the first and last book objects, if any, and display a proper message if they are the same.
