Boxing
Boxing is the process of converting a primitive type into an instance of the corresponding wrapper class. This allows primitives to be used as objects, which can be helpful when working with collections that can only hold objects, like ArrayList.

Unboxing
Unboxing is the reverse process, where an instance of a wrapper class is converted back to a corresponding primitive type.
