That piece of code definately seemed to do the job, however instead of a 
blank it return the word null. Is there a way to have the blank space listed 
instead? Sorry to be such a pest, but I'm sort of learning this on my own 
and am always looking for more info. Appreciate your help, and the others in 
this group.Once I have this done, I have other things that i'd like to play 
around with.

 I want to make a class similar to a dictionary that does has the same 
methods as this one. (I know one word and using a dictionary I get a bunch 
of other words, the definition). Basically methods similar to the previous 
stuff.  I got this example out of a text book I picked up at the library, 
however it doesn't have the answers and I'm kind of lost. Any help would be 
appreciated. thanks

Dictionary() - hold 4 entries

Dictionary(int n) - holds n entries

void add(String key, String value) - add the key/value plair to the 
dictionary. Also needs to be abble to change size

void remove (String key)- remove key/value pair from the dictionary known by 
the key

String lookup(String key) - returns the value associated with the key, if 
the key is not there return null

String[] lookupPart(String keyPart) - return a list of values whose keys 
have keyPart as a substring

String[] reverseLookup(String valuePart) - similar to above

Boolean contains(String key) - returns true/false is the key is in the 
dictionary

String to String() - returns a prinable representation of the dictionary, 
alphabetized by key.
