Welcome to Hands-On Automation Testing with Java for Beginners. This is the only book you will find on the internet that teaches every topic needed to emerge as a strong Java automation tester. It contains easy teaching and simple techniques to effectively handle Java-related automation/projects. Considering that we will cover each and every topic of core Java, with detailed explanations, this will really help us develop and grade our own Java automation projects.

All the core Java concepts are explained from scratch. We do not assume that readers have any prerequisite knowledge, so we consider all readers to be from a non-coding background, and we teach each and also support them with examples that we will use in real time. Hence, we will not stick to only theories.

When you check for courses in the market, you should try to learn one new concept. You just see three lines of definition followed by examples; that's all. But here, we will understand why, when, and where we are using the object-oriented programming systems (OOPS) concept in Java. There will also be proper programming examples, showing a particular OOPS concept in real-time usage. In this way, our book will drive through real-time projects; it's all about practical learning. This will come into play when we start with Java collections, such as core Java, which is one of the main concepts in our book since it is definitely required for you to start your basics and to develop an automation framework in your workplace. Also, since Java collections is one of the core parts, throughout the entire book we will take utmost care in providing all the necessary practical scenarios for each Java collection that we will discuss.

We will be working on tricky Java programs, looking at printouts, prime numbers, Fibonacci series, and pyramids. We will sort out print in descending order, looking at array matrices, and printing the maximum column numbers. This book will provide you with detailed strategies and tips that you will need to use when approaching and designing a logic for these programs. This will help you to think beyond the boundaries and get the logic that you will need to write difficult Java programs.

Programs discussed in this book derive from commonly asked questions during interviews in many companies. You will receive help with those questions, with detailed solutions, and the methodology to approach that logic. So, this book is mainly focused on core Java. We are not dealing with swings and buttons, which are out of scope for Java learning in this book.

In this book, we will be learning core Java, collections, and other concepts such as loops, classes, and arrays . These are more than enough for you to start and develop a Java project. Whichever field you are put in, the knowledge gained from this book will help you start testing in the automation projects right away.

This chapter will cover the following concepts:
