String Tokenizer

Question

I have a problem using StringTokenizer and File's as they cannot resolve each other..
Here is the code...
FileReader.java:
import java.util.*;
import java.io.*;
public class FileReader
     public static void main(String[] args) throws IOException
          FileInputStream in = new FileInputStream("farrago.txt");
          StringTokenizer st = new StringTokenizer(in);
          while (st.hasMoreTokens())
               System.out.println(st.nextToken());
I have tried File and FileInputStream, and nothing has changed with this problem
FileReader.java:11: cannot resolve symbol
symbol : constructor StringTokenizer (java.io.FileInputStream)
location: class java.util.StringTokenizer
StringTokenizer st = new StringTokenizer(in);
^
So, what do I do here?

Answer 1

Yeah, StringTokenizer can only tokenize Strings (hence the name.)
To use it on a file, you need to loop over each line of the file...
public class Test
    public static void main(String[] args) throws IOException
        BufferedReader reader = new BufferedReader(new FileReader("farrago.txt"));
        String line;
        while ((line = reader.readLine()) != null) {
            StringTokenizer st = new StringTokenizer(line);
            while (st.hasMoreTokens())  {
                System.out.println(st.nextToken());
}Be careful too .. your class was called FileReader, and this example is most neatly done by java.io.FileReader .. try to avoid naming your classes the same as existing ones. :-)
