Java Full Stack Developer Course

☕ Java Full Stack Developer Course

Module 1: Java Fundamentals & Architecture

• Introduction to Java: History, Features, and the WORA Concept (Write Once, Run Anywhere)

• Setup: Installing JDK, JRE, and Setting up an IDE (Eclipse/IntelliJ IDEA)

• Deep Dive into JVM: Understanding the inner workings of JVM, JRE, and JDK

• Variables & Data Types: Primitives, Literals, Type Conversion, and Casting

Module 2: Control Flow & Operators

• Operators: Arithmetic, Relational, Logical, and Assignment Operators

• Conditional Statements: if-else, if-else-if ladders, and the Ternary Operator

• Switch Statement: Traditional Switch vs Modern Switch Expressions (Java 12+)

• Looping Constructs: while, do-while, for loops, and Nested Loops

Module 3: Object-Oriented Programming (OOPs) — Core

• Classes and Objects: Object Theory and Memory Allocation

• JVM Memory Map: Understanding Stack and Heap Memory

• Methods: Method Declaration, Execution, and Method Overloading

• Encapsulation: Private Members, Getters, Setters, and the this Keyword

• Constructors: Default vs Parameterized, Constructor Overloading, and super() vs this()

Module 4: Arrays & Strings

• Arrays: 1D Arrays, Multi-Dimensional Arrays, and Jagged Arrays

• Array Enhancement: Enhanced for loop (For-Each) and Array of Objects

• String Manipulation: Immutable Strings vs Mutable Strings (StringBuffer and StringBuilder)

Module 5: Advanced OOPs Principles

• Inheritance: Single, Multilevel, and why Multiple Inheritance is not supported via classes

• Polymorphism: Compile-time vs Runtime Polymorphism (Dynamic Method Dispatch)

• Keywords & Specifics: final keyword, Packages, Access Modifiers, and Wrapper Classes

• Abstraction: Abstract Classes, Abstract Methods, and Inner Classes (including Anonymous Inner Classes)

Module 6: Interfaces & Functional Java

• Interfaces: Interface Syntax, Need for Interfaces, and Implementation

• Java 8 Features: Functional Interfaces and Lambda Expressions (with and without return types)

• Special Types: Enums (if/switch with Enum, Enum Classes) and Annotations

Module 7: Exception Handling & Multithreading

• Exception Handling: try-catch blocks, Multiple catch blocks, throw, throws, finally, and Custom Exceptions

• Multithreading: Thread Lifecycle, Creating Threads (extending Thread vs implementing Runnable)

• Thread Synchronization: Concurrency, synchronized keyword, Deadlocks, and the Producer-Consumer problem

Module 8: Collections Framework & Generics

• Generics: Need for Generics and Basic Implementation

• Collections API: List Hierarchy (ArrayList, LinkedList), Set Hierarchy (HashSet, TreeSet), and Queue (ArrayDeque)

• Map API: HashMap and LinkedHashMap

• Sorting & Utilities: Iterator, Comparator vs Comparable Interfaces

Module 9: Database Connectivity (JDBC)

• JDBC Architecture: Drivers and Setup

• CRUD Operations: Establishing Connection, Statement, PreparedStatement, and ResultSet with MySQL/Oracle
