Java is a versatile, object-oriented programming language widely used for building applications across platforms. Here’s a breakdown of its core concepts:

📚 1. Fundamentals

  • Syntax: Java uses a C-like syntax with curly braces {} for code blocks.
    Java_Syntax
  • Data Types: Includes primitive types (int, double, boolean) and objects.
  • Variables: Declared with type variableName = value;
  • Operators: Arithmetic (+, -, *, /), comparison (==, >, <), etc.

🛡️ 2. Object-Oriented Programming (OOP)

  • Classes & Objects: Blueprints for creating instances.
  • Inheritance: Extending classes to reuse code.
  • Polymorphism: Method overriding and interfaces.
  • Encapsulation: Bundling data with methods that operate on it.
  • Abstraction: Hiding complex implementation details.

📦 3. Packages & Imports

  • Packages: Organize code into namespaces (e.g., java.util).
  • Imports: Use import package.name; to access classes.

🧠 4. Key Features

  • Platform Independence: "Write once, run anywhere" via JVM.
  • Memory Management: Automatic garbage collection.
  • Multithreading: Concurrent execution of tasks.
