这条例子总是错误的,应该怎样改正?
/********* Token.java*********/
import java.io.*;
public class Token
  {
  public static void main(String args[]) throws IOException
    {
    BufferedReader br=new BufferedReader(
                      new FileReader("linenum.txt")); 
    BufferedWriter bw=new BufferedWriter(
                      new FileWriter("token.txt"));
    StreamTokenizer st=new StreamTokenizer(br);
    int tokenType;
    st.whitespaceChars(0,32);
    st.eollsSignificant(true);
    while(br.ready())
      {
      tokenType=st.nextToken();
      switch(tokenType)
        {
      case st.TT_NUMBER:
        bw.write(String.valueOf((long)st.nval));
        bw.newLine();
        break;
      case st.TT_WORD:
        bw.write(st.sval);
        bw.newLine();
        break;
      default:
        ;
        }
      } 
    bw.close();
    }
  }

编译通过
