Googling for "java wrapper classes" gives you a lot of useful information in a fraction of a second.

For example: http://en.wikipedia.org/wiki/Primitive_wrapper_class

As Jesper's Wikipedia link explains, autoboxing was introduced in Java 5. However, the wrapper classes themselves have been around since Java 1.1.
