java.io.StreamTokenizer.ordinaryChars(int low, int hi) 方法指定的范圍內(nèi)的所有字符C在low <= c <= high“ordinary”這個(gè)詞器。請(qǐng)參閱上一個(gè)字符為普通詳細(xì)信息，此時(shí)要用ordinaryChar方法。

聲明

以下是java.io.StreamTokenizer.ordinaryChars()方法的聲明

public void ordinaryChars(int low, int hi)

參數(shù)

low --該范圍的低端
hi -- 范圍的高階

返回值

這個(gè)方法沒(méi)有返回值

例子

下面的例子顯示java.io.StreamTokenizer.ordinaryChars()方法的用法。

package com.yiibai;

import java.io.*;

public class StreamTokenizerDemo {

   public static void main(String[] args) {

      String text = "Hello. This is a text 
 that will be split "
              + "into tokens. 1+1=2";
      try {
         // create a new file with an ObjectOutputStream
         FileOutputStream out = new FileOutputStream("test.txt");
         ObjectOutputStream oout = new ObjectOutputStream(out);

         // write something in the file
         oout.writeUTF(text);
         oout.flush();

         // create an ObjectInputStream for the file we created before
         ObjectInputStream ois =
                 new ObjectInputStream(new FileInputStream("test.txt"));

         // create a new tokenizer
         Reader r = new BufferedReader(new InputStreamReader(ois));
         StreamTokenizer st = new StreamTokenizer(r);

         // set chars a to e as ordinary
         st.ordinaryChars('a', 'e');

         // print the stream tokens
         boolean eof = false;
         do {

            int token = st.nextToken();
            switch (token) {
               case StreamTokenizer.TT_EOF:
                  System.out.println("End of File encountered.");
                  eof = true;
                  break;
               case StreamTokenizer.TT_EOL:
                  System.out.println("End of Line encountered.");
                  break;
               case StreamTokenizer.TT_WORD:
                  System.out.println("Word: " + st.sval);
                  break;
               case StreamTokenizer.TT_NUMBER:
                  System.out.println("Number: " + st.nval);
                  break;
               default:
                  System.out.println((char) token + " encountered.");
                  if (token == '!') {
                     eof = true;
                  }
            }
         } while (!eof);


      } catch (Exception ex) {
         ex.printStackTrace();
      }
   }
}

讓我們編譯和運(yùn)行上面的程序，這將產(chǎn)生以下結(jié)果：

Word: H
e encountered.
Word: llo.
Word: This
Word: is
a encountered.
Word: t
e encountered.
Word: xt
Word: th
a encountered.
Word: t
Word: will
b encountered.
e encountered.
Word: split
