wordChars( )方法用来指定可以用于字的字符范围。它的通常形式如下：

//Enhanced word count program that uses a StreamTokenizer.
import java.io.*;
class STWordCount{
 public static int intWords = 0;
 public static int intLines = 0;
 public static int intChars = 0;
 public static void wc(Reader r) throws IOException{
  StreamTokenizer tok = new StreamTokenizer(r);
  tok.resetSyntax();
  tok.wordChars(33,255);
  tok.whitespaceChars(0,' ');
  tok.eolIsSignificant(true);
  while(tok.nextToken() != tok.TT_EOF){
   switch(tok.ttype){
    case tok.TT_EOL:  //不知道为什么会报错
     intLines++;
        intChars++;
     break;
    case tok.TT_WORD:  //不知道为什么会报错
     intWords++;
    default: 
     intChars += tok.sval.length();
   }
  }
 }
 public static void main(String[] args)
 {
  if(args.length == 0){
   try{
    wc(new InputStreamReader(System.in));
    System.out.println(intLines + " " + intWords + " " + intChars);
   }catch(IOException e){
    
   }
  }else{
   int tWords = 0,tLines = 0,tChars = 0;
   for(int i =0;i<args.length;i++){
    try{
     intWords = intLines = intChars = 0;
     wc(new FileReader(args[i]));
     tWords += intWords;
     tLines += intLines;
     tChars += intChars;
     System.out.println(args[i] + ": " +intLines+ " " + intWords + " " + intChars);
    }catch(IOException e){
     System.out.println(args[i] +":error.");
    }
   }
   System.out.println("Total :" +tLines+ " " + tWords + " " + tChars);
  }
 }
}
