How to Learn Java for Automation Testers with Practice, Examples
Learn Java & Programming If you are a manual tester and want to be a QA automation engineer. Java concepts for automation testing are not simple to achieve it requires almost as much design and thoughts as needed for the software itself. This article will give you in detail information on how to learn Java for Testing with practice examples.
This article is an easy introduction to Java OOPS concepts in Selenium Automation Framework where You Will get complete knowledge on Java OOPS concepts with Practical implementations, how they can be used to model web applications, and how to write maintainable test code using them.
By learning java concepts for automation testing you will get the Ability to write any Java Program logic with the strategies, tips, and tricks to build Java Automation frameworks (Selenium, Appium, Rest API) from scratch.

While Implementing Java Object Oriented Concepts in Selenium Automation Framework to improve my framework, I always concentrate on the “complex points.” Below are the areas that are complex to set up where the most failures occur. three main areas that I wanted to simplify or improve on:
#1. ABSTRACTION
It is the method of Hiding the implementation of internal details and showing the functionality to the users.
Abstract Class: A class that contains an abstract keyword in its declaration then is an Abstract Class.
Syntax:
1 abstract class <class-name>{}
Abstract Method:
An abstract method is a method that is declared without an implementation (without braces, and followed by a semicolon), like this
Syntax:
abstract void myMethod()
#2. INTERFACE
Basic statement we all know in Selenium is WebDriver driver = new FirefoxDriver();
#3. INHERITANCE
The mechanism in Java by which one class acquires the properties (instance variables) and functionalities of another class is known as Inheritance.
Here we extend one class (Base Class like WebDriver Interface) into another class (like Tests, Utility Class) is known as Inheritance.
#4. POLYMORPHISM
Polymorphism will allow us to perform a task in multiple ways.
Both Overloading and overriding concepts combination is known as polymorphism. For in detail concepts follow the below-mentioned link.

#5. METHOD OVERLOADING
It is a method that was already implemented in another class by changing its parameters. If you can understand Overriding in Java you can understand this method.
Declaring a method in child class that is already present in the parent class is called Method Overriding. Examples are the get and navigate methods of different drivers in Selenium.
#6. METHOD OVERRIDING
Examples of Encapsulation are all the classes in a framework are. In POM classes, we declare the data members using @FindBy, and initialization of data members will be done using the constructor to utilize those in methods.
Encapsulation is a process of binding code and data (variables) together in a single unit.

Get started with Selenium with Java:
The most widely used in commercial applications is a java programming language as compared to other programming languages like Python and hence integrating Selenium tests it easier

Page Object Model in Selenium:
Page Object Model is an object design pattern in Selenium, where
Web pages are represented as classes, and the various elements on the page are defined as variables on the class. All possible user interactions can then be implemented as methods in the class.
For In-depth concepts of Page object Model, Selenium Java best practices and Page Factory follow the below link

Finally, as an open-source tool for developers and testers, it made easier for Automation testing using Selenium with Java. Java is a highly demanded and popular programming language Selenium with Java
