Setting up the Java Development Kit (JDK) and Integrated Development Environment4:37
Install JDK 23 and Visual Studio Code, then install the Java Extension Pack for Java support, debugging, and Maven. Verify the JDK in the terminal and begin writing main.java.
Basic Syntax: Variables, Data types, Operators.11:17
Master Java basics by exploring variables, data types, and operators, including integers, doubles, chars, booleans, and strings, then perform arithmetic, modulus, and logical comparisons with print statements.
Control Flow: Conditional Statements if-else, switch, Loops for, while, do-while13:22
Explore Java control flow by applying if-else, switch, and loops (for, while, do-while) through practical examples that print outcomes like positive, negative, and zero numbers.
Introduction to Object Oriented Programming (OOP) Concepts6:08
Explore object oriented programming in Java by modeling real world entities as objects with name and age, using attributes, a constructor, and a method to display information.

Classes and Objects: Creating, Instantiating, and Using6:17
Explore creating and using classes and objects in Java, with a person example showing attributes, a constructor, and a display method that outputs details.
Methods: Defining, Calling, and Overloading5:51
Explore how to define, call, and overload methods in Java to create modular, reusable code, illustrated with greeting and add numbers examples.
Encapsulation, Inheritance, and Polymorphism13:22
Explore encapsulation, inheritance, and polymorphism in Java by using private fields with public accessors, extending classes, and overriding methods for dog and cat sounds.
Access Modifiers: Public, Private, Protected5:54
Abstract Classes and Interfaces5:32
Explore abstract classes and interfaces in Java to define reusable blueprints. See a concise demonstration of an abstract class, an interface, and a class that extends and implements both.

Arrays: Declaration, Initialization, and Manipulation6:31
Explore how to declare, initialize, and manipulate arrays in Java using a practical example that stores integers, prints elements, and updates a value at index two.
Strings: Methods, Manipulation, and Operations11:42
Explore Java strings and core methods, including length, uppercase and lowercase, concatenation, comparison, substring, replace, split, and join, with practical examples.
Collections Framework: ArrayList, LinkedList, HashMap, HashSet9:56
Explore the Java collections framework with ArrayList, LinkedList, HashMap, and HashSet. Learn their differences and how to use them in your Java programs.
Introduction to Algorithms: Linear, Binary, Bubble, Selection, Insertion16:27

What Are Exceptions? Types of Exceptions9:50
Explore what exceptions are and how to handle them in Java. Show examples of checked, unchecked, and error types, including file not found, index out of bounds, and stack overflow.
The Try Catch Finally Block4:56
Learn how to handle exceptions in Java with try, catch, and finally to keep programs running. Finally executes regardless of errors, as shown by a sample out of bounds scenario.
Throwing Exceptions5:31
Learn how throwing exceptions in Java improves robustness by validating input, using try-catch blocks, and illegal argument exceptions to prevent abrupt termination.

Reading From and Writing to Files9:15
Learn to read from and write to files in Java with FileWriter, FileReader, and BufferedReader, using try-with-resources and basic error handling for reliable file operations.
Working with Streams: Input Streams, Output Streams9:40
Explore how Java streams enable reading and writing data with input and output streams, including file input and file output streams, byte handling, and safe exception handling.
File Handling and Manipulation9:13
Learn how to create, write, read, and delete a file in Java with a simple example using file writer and scanner. See the setup to deletion flow in action.
Serialization and Deserialization10:31
Master serialization and deserialization in Java by saving an object's state to a file, restoring it later, and transferring data across a network.
