/**
* The string tokenizer class allows an application to break a
* string into tokens. The tokenization method is much simpler than
* the one used by the <code>StreamTokenizer</code> class. The
* <code>StringTokenizer</code> methods do not distinguish among
* identifiers, numbers, and quoted strings, nor do they recognize
* and skip comments.
* <p>
* The set of delimiters (the characters that separate tokens) may
* be specified either at creation time or on a per-token basis.
* <p>
* An instance of <code>StringTokenizer</code> behaves in one of two
* ways, depending on whether it was created with the
* <code>returnDelims</code> flag having the value <code>true</code>
* or <code>false</code>:
* <ul>
* <li>If the flag is <code>false</code>, delimiter characters serve to
* separate tokens. A token is a maximal sequence of consecutive
* characters that are not delimiters.
* <li>If the flag is <code>true</code>, delimiter characters are themselves
* considered to be tokens. A token is thus either one delimiter
* character, or a maximal sequence of consecutive characters that are
* not delimiters.
* </ul><p>
* A <tt>StringTokenizer</tt> object internally maintains a current
* position within the string to be tokenized. Some operations advance this
* current position past the characters processed.<p>
* A token is returned by taking a substring of the string that was used to
* create the <tt>StringTokenizer</tt> object.
* <p>
* The following is one example of the use of the tokenizer. The code:
* <blockquote><pre>
* StringTokenizer st = new StringTokenizer("this is a test");
* while (st.hasMoreTokens()) {
* System.out.println(st.nextToken());
* }
* </pre></blockquote>
* <p>
* prints the following output:
* <blockquote><pre>
* this
* is
* a
* test
* </pre></blockquote>
*
* <p>
* <tt>StringTokenizer</tt> is a legacy class that is retained for
* compatibility reasons although its use is discouraged in new code. It is
* recommended that anyone seeking this functionality use the <tt>split</tt>
* method of <tt>String</tt> or the java.util.regex package instead.
* <p>
* The following example illustrates how the <tt>String.split</tt>
* method can be used to break up a string into its basic tokens:
* <blockquote><pre>
* String[] result = "this is a test".split("\\s");
* for (int x=0; x&lt;result.length; x++)
* System.out.println(result[x]);
* </pre></blockquote>
* <p>
* prints the following output:
* <blockquote><pre>
* this
* is
* a
* test
* </pre></blockquote>
