package  as;

import  java.util. * ;
public   class  StringTokenizerText {

     /**

      */
     public   static   void  main(String[] args) {
         if (args.length == 0 )
            System.out.println( " 请输入参数 " );
      try  {
        BufferedReader br  =   new  BufferedReader( new  InputStreamReader( new  FileInputStream(args[ 0 ])));
        BufferedWriter bw  =   new  BufferedWriter( new  OutputStreamWriter( new  FileOutputStream(args[ 1 ])));

        String ii = br.readLine();
        
         while (ii != null )
