/*

Hashtable class is designed to create a collection in which to store its elements is a hash table.
* Information is stored in a hash table by using a mechanism called hashing.
* When hashing to determine the unique value called a hash code, using the information content of a special key.
* Summarized hash code serves as an index into a table in which desired data stored corresponding to the specified key.
* Converting a key in the hash code is executed automatically,
* and therefore it is the hash code is not available to the user at all. The advantage of hashing is that it provides a constant-time search operations, retrieving and setting values ​​irrespective of the magnitude data arrays.
