Wrapper classes are classes that are used to make primitive
data types into objects, and to make wrapped objects into
primitives because
As we know that vector in java can hold only object; but
can't directly store primitive data types, like int,float,
char, long, double. therefore we need to convert simple data
type to object. This can we done using wrapper classes.
