Learn Java Step by Step for Test Automation from ground-up.

Install Eclipse on Windows, download and unzip the 64-bit package, launch Eclipse, create a workspace and a Java project, then run a class that prints welcome to test automation.

Move eclipse files to a dedicated folder on the C drive, then use workspace and preferences features to run Java applications, view console output, and manage problems for test automation.

Declare and initialize variables in Java, explore the int data type, and perform a simple addition. Print the result to the console using System.out.println.

Explore the anatomy of a Java class, showing how code and data form a program within an object‑oriented class. Learn about packages, imports, variables, methods, and compiling to class files.

Demonstrate the main method as the JVM’s entry point to start a Java program. Understand its syntax—public static void main(String[] args)—and how it runs with a string array input.

Discover how constructors initialize object state in Java and how the this operator lets you assign values in a single constructor call, avoiding multiple setters.

Organize Java files with packages, then import existing functionality from the Java API, such as the Date class, and grasp class versus method level variables and access modifiers.

Explore object oriented programming with encapsulation, abstraction, inheritance, and polymorphism, and see how a class and its object model employee data through private members and public accessors.

Explore polymorphism in Java, enabling one interface to support multiple implementations. Learn method overloading and overriding, and distinguish compile-time (static) from runtime (dynamic) polymorphism.

learn how loops repeat code using for and while constructs in Java, test loop behavior in Eclipse, and apply age-based conditional logic to print unknown, teenager, or adult outcomes.

Create a file in Java with File, FileWriter, and BufferedWriter, then read it back with FileReader and BufferedReader, handling exceptions, to pass test outputs between automation steps.

learn to read user input from the command line in Java using the Scanner class, prompting for salutation and a message, and printing the combined output.

Learn how to read a properties file in Java using a class loader, enabling externalized config values like environment URLs and driver paths for test automation.

Master Java foundations by connecting Eclipse setup to variables, data types, methods, access modifiers, strings, and collections, then explore abstraction, encapsulation, inheritance, and polymorphism.
