Core Java for Beginners – Foundation for Automation Testing

Choose IntelliJ as the IDE for Java automation testing, avoiding Eclipse's performance issues; this course covers data types, operators, loops, arrays, classes, inheritance, collections, exceptions, and Selenium usage.

Explore how Java keywords are reserved words with predefined meanings. Know that keywords cannot be used as variable, method, or class names, and that true, false, and null are literals.

Discover how public static void main drives Java programs, understand each component (public, static, void, main, string of arguments), and write a simple class with System.out.println to run.

Explore how a car class acts as a blueprint for objects, outlining properties and actions, and learn object creation and method invocation via a main method.

Explore constructors in Java, a special method that creates and initializes objects automatically when using new, with default and parameterized forms and constructor overloading.

Explore Java constructors, including default and parameterized forms, and constructor overloading for flexible object creation. Learn when to use each constructor and how they differ from methods.

Master abstract classes in java by examining abstract and non-abstract (concrete) methods, and understand why abstract methods compel subclass implementations using an animal example.

Explore the two main Java data type categories—primitive and non-primitive—and learn the size, default values, and typical uses of byte, short, int, long, float, double, char, and boolean.

Explore primitive data types in Java by coding examples that use byte, short, int, long, float, double, char, and boolean, printing values with system.out.println in a main class.

Explore how Java variables work as data containers, covering local, instance, and static variables, with examples of data types, names, and values in a student class.

Explore how for, while, and do-while loops repeat code in Java, including initialization, conditions, and increments, with practical examples and iteration concepts.

Explore if and else conditional statements in java, including nested if and if else if, and see how true conditions execute code while false paths skip.

Explore nested if statements in Java, showing how condition one and condition two govern which statements execute; compare with if else and if else if constructs, with number examples.

Learn how the Java switch case statement selects among multiple options with clean code, using a pizza order example to illustrate cases, break, and default behavior.

Explore strings in Java as immutable non-primitive types, compare literal versus new keyword creation, and learn memory placement in the constant pool and heap, plus operations like length and charAt.

Explore string manipulation in Java by replacing characters with a string method, identifying the longest word in a sentence, and sorting characters alphabetically using a char array.

Explore how the static keyword in Java assigns members to the class, enabling access without objects and aiding memory management, including static blocks, variables, and methods.
