Java Basics

Welcome to the world of Java! Java is a widely-used programming language known for its "write once, run anywhere" philosophy. In this section, we'll cover the basics of Java to help you get started on your journey.

What is Java?

Java is a high-level, class-based, object-oriented programming language. It was developed by Sun Microsystems and released in 1995. Java is platform-independent, which means it can run on any device that has a Java Virtual Machine (JVM).

Features of Java

• Object-Oriented: Java is an object-oriented programming language, which means it uses objects and classes to structure the code.
• Platform-Independent: Java code can run on any device with a JVM, making it highly portable.
• Robust: Java is designed to minimize errors that can occur at runtime, such as null pointer exceptions.
• Secure: Java provides a secure environment for running applications, thanks to its built-in security features.
• Multithreaded: Java supports multithreading, which allows you to write programs that can execute multiple tasks concurrently.

Getting Started

To start coding in Java, you'll need:

• Java Development Kit (JDK): This is the software you need to compile and run Java code.
• Integrated Development Environment (IDE): An IDE like IntelliJ IDEA or Eclipse can help you write, debug, and run Java code more efficiently.

Sample Code

Here's a simple "Hello, World!" program in Java:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
