Primitive wrapper class

A wrapper class is generated according to the design pattern of an adapter class, usually surrounds the primitive types used in some object-oriented languages ​​. In this way all object- oriented features such as over charge, discharge, etc., are in principle, allows for these types.

Examples of wrapper classes are the so-called primitive wrapper classes, where then the applied according to these type variable inherits all the properties of the parent classes. As an example, the Grundwrapperklassen for Java:

The Byte, Short, Integer, Long, Float, and Double wrapper classes are all derived from the Number class. For the non- void type, the wrapper class Void exists.
