* TestStringTokenizer class gives three examples to demonstrate common usage of the StringTokenizer class.

*

This sample code runs

*

* --------- TEST1 ---------
* Name
* Telephone
* Fax
* email
* Address
* --------- TEST2 ---------
* Name
* Telephone
* Fax
* email
* Address
* --------- TEST3 ---------
* The
* file
* Good java code.txt
* IS
* in
* DIR
* My Documents
* of
* Volume
* DOC VOLUME

* Demo the most common usage of StringTokenizer, use StringTokenizer (String, String)
* Construct the tokenizer.
* @see java.util.StringTokenizer # StringTokenizer (String, String)
* @see java.util.StringTokenizer # HasmoreToKens ()
* @see java.util.StringTokenizer # nextToken ()
* /

/ **
* Demonstrating the NEXTTOKEN (String) usage of StringTokenizer
* @see java.util.StringTokenizer # StringTokenizer (String)
* @see java.util.StringTokenizer # HasmoreToKens ()
* @see java.util.StringTokenizer # nextToken (String)

* A more comprehensive example, it splits one sentence, split each word, where
* Several words contained in double quotes are processed as a word output.
