What to do if a program does not recognize String Tokenizer?

Everytime I try to run the following Java program it says "No match found for constructor String Tokenizer (java.lang.string)"...What should I do? I dont think the code is wrong itself...





// The "StringTokenizer" class.


import java.io.*;


import java.util.*;


import hsa.Console;





public class StringTokenizer


{


static Console c; // The output console





public static void main (String [] args) throws IOException


{


c = new Console ();


BufferedReader script;


PrintWriter censor;


script = new BufferedReader (new FileReader ("a.txt"));


censor = new PrintWriter (new FileWriter ("b.txt"));


String word;


while (true)


{


String line = script.readLine ();


if (line == null)


break;


StringTokenizer words = new StringTokenizer (line);


while (words.hasMoreTokens ())





{


word = words.nextToken ();


if (word.length () == 4)


{


censor.println (word);


}


}


}


script.close ();


censor.close ();

um, you don't have a constructor, like the error says.





The constructor of a class should is a method with the same name as the class and it is called to instantiate an object of that class.





this line: StringTokenizer words = new StringTokenizer (line);


you need to define what StringTokenizer(String s) is.
