Wrapper classes are used to wrap primitive values so that they can be used as objects, if there is a need to. Such as inserting in Collections, etc.

Bosun gave a nice definition. Here's an example: You've probably seen: int x; This creates the integer variable 'x'. But you could also use an Integer wrapper, so that 'x' is treated as an object: Integer x = new Integer(); From the Sun documentation: "The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int. " There's a wrapper class for each primitive type.
