StringTokenizer undefined?

I could have swore I was doing everything right, but no matter what I
try I end up getting the following error:

Exception in thread "main" java.lang.Error: Unresolved compilation
problem:
The constructor StringTokenizer(String, String) is undefined

at StringTokenizer.main(StringTokenizer.java:8)

Here is my code:

import java.util.*;

public class StringTokenizer
{
public static void main(String[] Args)
{
String ssn = "123-34-7948";
StringTokenizer ssnToken = new StringTokenizer(ssn, "-");
}
}

What's am I doing wrong?

Not defining a constructor for StringTokenizer. Of, if you want to
construct a java.util.StringTokenizer, you need to say so, because you've
asked to construct an instance of *your* StringTokenizer class. You'd need
to say

java.util.StringTokenizer ssnToken = new java.util.StringTokenizer(ssn,
"-");

The simplest fix is to call your class something else.

Im still really new to programming and my java 1 class is online so I
may be confusing myself here... the class name is ssnToken, correct? I
tried adding the java.util onto the StringTokenizer, but that did not
work. I use eclipse as my IDE and it tells me there error is on the new
'StringTokenizer(ssn, "-");' part of the line. It says: The constructor
StringTokenizer(String, String) is undefined

The cause of the error is you using the name of a Java core API class,
which is, or happens to be, StringTokenizer. Rename your class. How
about public class SeanWashington. The error should go away.

Your class name is fatally wrong.
It hides *real* StringTokenizer.
