}Inheritance in Java
Java Inheritance (Subclass and Superclass)
In Java, it is possible to inherit attributes and methods from one class to another. We group the "inheritance concept" into two categories:
subclass (child) - the class that inherits from another class
superclass (parent) - the class being inherited from
To inherit from a class, use the extends keyword.inheritance in java
it is used to define relationship between two class,
which a child class occurs all the properties and
behaviours of a parent class.
Provides code reusability.
Ex: in my framework I have a TestBase
class which I store
all my reusable code and methods.
My test execution classes and
elements classes will extend the
TestBase in order to reuse the code.Copyright © 2021 Codeinu
