The Java compiler automatically converts primitive types to their equivalent object wrapper classes, which is known as autoboxing. Converting an int to an Integer, a double to a Double, and so on are examples. Unboxing occurs when a conversion occurs in the opposite direction.

Developers can build cleaner, easier-to-read code by using autoboxing and unpacking. We may utilise primitive types and Wrapper class objects interchangeably thanks to this method, which eliminates the requirement for explicit typecasting.

The main difference between boxing and unboxing is that boxing refers to the conversion of a value type to an object type, whilst unboxing refers to the opposite.

A link between value-types and reference-types can be established by allowing any value of a value-type to be changed to and from a type object via boxing and unpacking. Boxing and unpacking provide you a unified view of the type system, allowing you to treat any value of any type as an object in the end.

It is required because programmers can write code directly and the JVM will handle the boxing and unboxing. Each of Java's eight primitive types (byte, short, int, float, char, double, boolean, long) has its own Wrapper class.
