Adaptor design Pattern

It consiste of a class which acts a a bridge between two different and independent classes.

When an interface is not compatible with a class , An adapter is used to make it compatible
   
customer_list  is a class which contains employee list in two dimensional string array.
the client class accept employee name in array list . The adaper design pattern becomes
handy in such scenario but doing the required conversion of the two dimensional string
array to list of name for the employees.
