我自己学习JAVA过程中用键盘敲的代码

DateLine(InputStream in)(计算字符和行数)
{ DataInputStream data=new    
                                          DataInputStream(in);
   String currentLine;
   int lineCount=0; int charCount=0;
   while((currentLine=dataIn.readLine())!=null)
   {  ++lineCount;
      charCount+=currentLine.length();
   }
   return (charCount/(float)lineCount);
}
