Primitive wrapper class

In object oriented programming and in the Java language in particular, a wrapper class is a class that encapsulates types, so that those types can be used to create object instances and methods in another class that need those types. So a primitive wrapper class is a wrapper class that encapsulates, hides or wraps data types from the eight primitive data types, so that these can be used to create instantiated objects with methods in another class or in other classes,. The primitive wrapper classes are found in the Java API.
