Page Object Model design pattern code example

Example: what is page object model design pattern

Pom basically Creating java classes
for the each page of our application,
and storing related webelements,
and methods in their respective classes.
    
Advantages of POM =
First of all, it makes our code REUSABLE.
I don't have to repeatedly locate web elements
in every single other class.
Secondly it is EASY TO MAINTAIN. I store one
webelement in one class and it is a lot easier to
fix any issue with that web element because I know
exactly where everything is stored.
Thirdly is seperating webelements and our test cases.
Our test cases will be cleaner therefore 
easy to manage overall.

HOW I CREATE POM =  
#1-I Create constructor, 
and pass PageFactory.initElements(objectOfClass, Driver)
#2- I use @FindBy annotation to locate web elements
            - FindBy annotation comes from Selenium.
