Symbol table class

Java includes a Hashtable class which makes setting up the symbol table class trivial. You will need to implement a dump table method (see below).

This is what you need to implement for the symbol table calss:

Class data member

Class behavior

Class relationships

Constructor

Destructor

Dump table contents

Shows all entries currently in the hash table and their locations, in terms of (1) the hash table cell and (2) position on the linked list. Use the entry's print function (defined for each type of symbol table entry--see Symbol table entry class) to print the entry contents. Example output for 3 names occupying two cells of the hash table (e.g., "a" and "bbx" both hashed to location 2; "bbx" was inserted before "a"):
```
           Cell       Entries
            2         name: a 
                      name: bbx
            4         name: fred
```
Gives statistics indicating
- tablesize
- number of non-empty cells
- average number of entries per cell.

Hash functions

You are free to use these, but if you do you must explain how they work in a comment at the head of the function definition.
