Scanner class is predefined class in java which is final in nature so we can not inherit it.

[HUMORLYST]

The `Scanner` class in Java is neither a `final` class nor an `abstract` class. It is a concrete class that can be instantiated, and you can create objects of the `Scanner` class to work with input sources such as the keyboard, files, or strings.

In Java, a `final` class cannot be subclassed, and an `abstract` class is typically used as a base class for other classes, allowing for abstraction and the definition of common methods that must be implemented by its subclasses. The `Scanner` class is designed for general-purpose input parsing and doesn't fall into these categories.
