Java Basics Documentation

Documentation for fundamental Java programming concepts.

Topics

• Variables and Data Types - Understanding Java's type system
• Operators - Arithmetic, logical, and bitwise operations
• Control Flow - Conditional statements and loops
• Arrays - Working with single and multi-dimensional arrays
• Strings - String manipulation and operations

Quick Reference

Primitive Data Types

• byte: 8-bit integer
• short: 16-bit integer
• int: 32-bit integer
• long: 64-bit integer
• float: 32-bit floating point
• double: 64-bit floating point
• boolean: true or false
• char: 16-bit Unicode character

Common Operations

// Variable declaration
int number = 42;
String text = "Hello";

// Arrays
int[] numbers = {1, 2, 3, 4, 5};

// Control flow
if (condition) {
    // code
} else {
    // code
}

for (int i = 0; i < 10; i++) {
    // code
}

Learning Path

1. Start with data types and variables
