Java - A Modern General-Purpose Programming Language
Java is a high-level, class-based, object-oriented programming language on the Java Virtual Machine (JVM). It's designed to be platform-independent, meaning code written once can run on any device with a JVM installed.
Key Features
- Platform Independence: "Write Once, Run Anywhere"
- Object-Oriented: Supports concepts like classes, objects, inheritance, and polymorphism.
- Robust: Designed to prevent common programming errors.
- Secure: Offers built-in security features.
- Simple: Designed to be easy to learn and use.
- Dynamic: Supports dynamic typing.
Core Concepts
Understanding these concepts is crucial for becoming proficient in Java:
- Classes and Objects: The building blocks of Java programs.
- Inheritance: Allows creating new classes based on existing ones.
- Polymorphism: Allows objects of different classes to be treated as objects of a common type.
- Interfaces: Define a contract that classes must implement.
- Abstract Classes: Partially implemented classes that can be extended.
- Exception Handling: Handles errors gracefully.
