doubts about primitives types

[André Asantos]

please anybody else knows what Wrappers means? Are from JSE 5 right? And any primitive type has a wrapper class as java.lang.Double from double right?


Thank you very much,

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.
