Java wrappers are classes that wrap up primitive values in classes that offer utility methods to manipulate the values. If for example you want to store a set of int values in the elements of a Vector, the values in a Vector must be objects and not primitives. When you want to retrieve the values wrapped up in the Integers that are in the Vector elements you will need to cast the elements back to Integers
