How & What should you learn in Java for Selenium Automation Testing?

This is one of the most common questions we get these days. We would like to address this question in several sections, which will provide you with greater clarity regarding the amount of Java required for a career in test automation. Aside from this, we are including a set of instructional videos that we created to inspire the test automation community and advance their careers.

Before jumping into the topic, let’s discuss the Selenium tool briefly.

Selenium is widely recognized as the most prominent tool in the domain of automation testing, whereas Java is the most extensively utilized programming language in the present market. Both of these tools work well together to automate testing.

Selenium is a popular tool that people use to automate tests on web browsers. It’s free and easy to use. To put it differently, Selenium is exclusively capable of testing web applications. You can’t use Selenium to test any computer or mobile program.

Its time to jump on the main topic…

What to learn in Java for Selenium?

Introduction to Java – Prior to acquiring proficiency in any programming language, it is advisable to acquire knowledge about its history, its characteristics, and the various components that comprise it. Our training will introduce you to Java, its history, and its features. We will also learn about some terminologies, such as Java Development Kit, Java Runtime Environment, and Java Virtual Machine.
Java download and installation – Next, we will teach you how to install Java on your computer and set up the settings for the environment. Well then set up an integrated development environment, called Eclipse, and run our initial Java program, called HelloWorld.java, on Eclipse.
Basics of Java programming – In the subsequent segment, we shall elucidate the fundamental components of the Java language, namely variables, data types, operators, conditional statements, loops, methods, classes, and objects. Each concept will be elaborated through the utilization of code snippets, which can be utilized for practicing purposes.
OOPS concepts – In this segment , we will teach about the OOPS or the Object-Oriented Programming concept in Java. Then, we’ll dive into the four fundamentals of OOPS – inheritance, encapsulation, polymorphism, and abstraction – in greater detail, aided by real-world scenarios and code fragments.
String handling in Java – In this segment, you will study string handling in Java. This segment has been specifically crafted to assist you with all the common String functions that will prove to be immensely beneficial in the realm of automation.
Exception Handling in Java – Subsequently, we shall be introduced to Exception handling, which is regarded as one of the most significant aspects of Java programming. This lets you handle different errors during runtime by using keywords like try, catch, and finally.
