大致如下：

BufferedReader fp = new BufferedReader (new FileInputStream ("filename.csv")) ;

FileWriter o = new FileWriter ("newfile.csv") ;

String line = null ;

while ((line = fp.readLine ()) != null)

{

String s = line.replace ("\"" , "") ;

o.write (s) ;

o.write ("\\O\r\n") ;

}

fp.close () ;

o.flush () ;

o.close () ;
