Welcome to the Java Basic Syntax tutorial! Java is a powerful programming language that forms the foundation of many applications. Let's dive into its core elements.

🧩 Core Syntax Elements

1. Variables & Data Types

Java requires explicit declaration of variables:

int age = 25; // Primitive type
String name = "John"; // Object type

📌 Tip: Always match variable types to their usage. Use double for floating-point numbers and boolean for logic!

2. Operators

Common operators include:

  • Arithmetic: +, -, *, /
  • Comparison: ==, !=, >, <
  • Logical: &&, ||, !

3. Control Structures

if (condition) {
    // Code block
} else if (anotherCondition) {
    // Alternative block
} else {
    // Default block
}

Use for, while, and do-while for looping. 🌀

💻 Example Code

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