#day2 of #90dayschallenge | Variables and Data types in Java

Ready to dive into the fundamentals of Java? In this video, we’re breaking down the essentials of variables and data types in Java, complete with practical code examples to help you master these core concepts! 🚀

🔍 What You’ll Learn:

Understanding Variables 🏷️ Learn how to declare, initialize, and use variables in Java. We’ll walk through simple examples to show you how variables store and manipulate data.

int age = 25;
String name = "Alice";
Exploring Data Types 📊 Get to know Java’s data types, including primitive types (such as int, double, char) and reference types (like String and arrays). See practical examples of each:

// Primitive Types
int number = 10;
double price = 19.99;
char grade = 'A';

// Reference Types
String greeting = "Hello, World!";
int[] numbersArray = {1, 2, 3, 4, 5};
Type Conversion and Casting 🔄 Discover how to convert between different data types, both implicitly and explicitly. We’ll demonstrate with code how to perform type casting safely.

// Implicit Conversion
double result = 10 / 4; // 2.5

// Explicit Casting
int roundedResult = (int) 2.5; // 2
Best Practices and Common Pitfalls ⚠️ Learn best practices for using variables and data types effectively and avoid common mistakes that new programmers often make.

Whether you’re a beginner looking to get started or someone who needs a refresher, this video provides clear explanations and practical examples to build your confidence with Java variables and data types.
