What is Autoboxing and Unboxing in Java? | Java Autoboxing and Unboxing | Java Tutorial

Welcome to this Java tutorial where we explore autoboxing and unboxing in Java programming!

Autoboxing and unboxing are features introduced in Java to automatically convert primitive data types to their corresponding wrapper classes and vice versa. Autoboxing simplifies the process of converting between primitive types and wrapper classes, making Java code more concise and readable. In this video, we'll dive deep into understanding autoboxing and unboxing and how they work in Java.

Key topics covered in this tutorial include:
- **Understanding Autoboxing and Unboxing**: Explanation of what autoboxing and unboxing are and their purpose in Java programming.

- **Autoboxing**: Learn how autoboxing automatically converts primitive types (such as `int`, `double`, `boolean`) to their corresponding wrapper classes (`Integer`, `Double`, `Boolean`) when needed.

- **Unboxing**: Explore how unboxing automatically converts wrapper classes back to primitive types when required.

- **Use Cases for Autoboxing and Unboxing**: Discuss scenarios where autoboxing and unboxing are useful, such as collections that require wrapper classes or method parameters that expect primitive types.

- **Benefits of Autoboxing and Unboxing**: Understand the advantages of using autoboxing and unboxing in terms of code readability and ease of development.

- **Performance Considerations**: Discuss performance implications of autoboxing and unboxing and best practices for efficient usage.

- **Examples and Demonstrations**: Walk through practical examples to illustrate the usage and benefits of autoboxing and unboxing in Java programming, showcasing different scenarios and use cases.

By the end of this tutorial, you'll have a solid understanding of how autoboxing and unboxing work in Java and how to leverage these features to write cleaner and more expressive code.

Since Java 9, new Integer( value ) is deprecated in favor of Integer.valueOf( value ) -- but otherwise very good.
