Wrapper Classes in Java
🚀 *Java Wrapper Classes Explained | Autoboxing, Unboxing & When to Use Them*
In this video, we take a deep dive into *Java Wrapper Classes**—an essential concept for understanding how Java bridges the gap between **primitive types* and **objects**. Wrapper classes play a critical role in collections, generics, APIs, and real-world backend development.
You’ll learn **what wrapper classes are**, **why they exist**, and **when you should use them instead of primitives**.
📌 *Topics covered in this video:*
What wrapper classes are in Java
Wrapper classes for each primitive
(`Integer`, `Double`, `Boolean`, `Character`, etc.)
Why collections and generics require wrapper classes
*Autoboxing and unboxing* explained
Performance and memory considerations
Common pitfalls (null values, unnecessary boxing)
Real-world use cases in Spring Boot and backend systems
👨💻 *Who this video is for:*
Java beginners building strong fundamentals
Full-stack developers working with Java backends
Developers using **Spring Boot**, collections, and APIs
Anyone preparing for Java technical interviews
💡 By the end of this video, you’ll clearly understand how wrapper classes work under the hood and how to make smart decisions between primitives and objects in production code.
