}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
