Java Tutorial for Beginners | Day 2 | Type Casting in Java
Welcome to Day 2 of the Java Programming Series! 🚀
In this video, we explore one of the most important concepts in Java programming: Type Casting.
You'll learn what type casting is, why it is used, and how Java converts values from one data type to another. We cover both Widening Casting (Implicit Casting) and Narrowing Casting (Explicit Casting) with practical examples to help you understand how data conversion works in Java.
We also discuss Data Loss and Overflow, understand Type Promotion, learn why byte + byte results in an int, and explore char ↔ int conversions using Unicode values. Finally, we'll see how type casting affects expressions and solve some common interview questions.
