Considering we use Java as a programming language used for Selenium automation, in this chapter, we will learn prerequisites required for Selenium automation. We will have to look at the basics of core Java, which is very much required for Selenium WebDriver. And also, we will learn to understand a few object-oriented concepts taking Java as a programming language.

At the end of this chapter, we will be in a position to write basic programs using core Java and will be able to understand the OOPs concepts as well, where we can use the concepts and basic programming while doing Selenium automation.
