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

Explore the basics of programming and Java for test automation, define what programming is, and demonstrate how to sum two numbers using Java, highlighting logic, syntax, and platform independence.

Set up your Java environment by installing the Java Development Kit and Eclipse, verify the installation from the command line, and learn to configure Java paths for test automation.

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 Java data types by focusing on char and boolean. Learn to declare, assign a single character, print values, and understand boolean true/false and common pitfalls with character constants.

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.

Explore Java access modifiers (public, private, protected, and default) and learn how they govern access to classes, variables, methods, and constructors within packages and through inheritance.

Create and name a Java class in Eclipse, and declare class-level and instance variables. Implement a multiply method with two parameters and a return value, plus a main entry point.

Explore the difference between class and object in Java, learn how to instantiate a class into an object, and see how blueprints become objects with properties, behaviors, and constructors.

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 abstraction in object-oriented programming, distinguishing it from encapsulation by hiding details and exposing essential methods via abstract classes and interfaces, with animal, dog, and cat examples.

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 inheritance in Java by defining a superclass with common behavior, and extending it into subclasses like dog and cat to reuse eat, sleep, and move methods, with optional overrides.

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.

Explore how arithmetic, relational, and logical operators work in Java, with practical examples and code demonstrations in Eclipse to compare values and evaluate conditions.

Explore how conditional statements and loops drive logic in Java from ground up, using if, else if, and else, boolean conditions, and operators to control program flow.

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.

Develop proficiency with Java collections by storing employee objects in an array list, exploring list and map concepts, and adding and retrieving data from a single collection.

Learn to traverse an array list of employees using an iterator and an enhanced for loop, printing each employee's name to verify the list contents.

Master hash maps in java by storing key value pairs, adding with put, and iterating via entrySet or enhanced for loop, comparing with lists for employee id name data.

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 run Java programs from the command line, compile with javac, and read inputs via main args and the scanner, print to the screen, and concatenate arguments.

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.

Build a command-line java mini project that creates and lists employees using getters and setters, and stores entries in an array list via a user-driven loop.

Learn to compile and run a Java mini project from the command line, using javac and java, and interact with a menu to add, list, delete, or exit.
