Java Autoboxing and Unboxing: What's the Difference?

A. 'Autoboxing is the process of wrapping primitive data types into objects, while unboxing is the process of converting wrapper classes to primitive data types.' This is the correct statement about the purpose of autoboxing and unboxing. Autoboxing and unboxing were introduced in Java to provide a way to seamlessly convert between primitive types and their corresponding object types (wrapper classes) without having to manually write the conversion code. For example, autoboxing allows you to assign a primitive value to an object reference of its corresponding wrapper class, while unboxing allows you to extract the primitive value from the wrapper object.
