Java Quiz on the concepts of objects, method overriding, inheritance, abstract class and super.

Inheritance in Java is an important concept in object-oriented programming. It allows you to create new classes that are built upon existing classes. This can be useful for code reuse, as you can inherit the properties and methods of an existing class without having to rewrite them.

There are five types of inheritance in Java:
Single inheritance: This is the simplest type of inheritance, where a class inherits from a single parent class.
Multilevel inheritance: This type of inheritance occurs when a class inherits from a parent class, which in turn inherits from another parent class.
Hierarchical inheritance: This type of inheritance occurs when multiple classes inherit from a single parent class.
Hybrid inheritance: This type of inheritance is a combination of multiple types of inheritance.
Multiple inheritance: Java does not support multiple inheritance. This is because it can lead to ambiguity, as the child class would not know which parent class's method to call if both parent classes have the same method.
