关于BufferedReader的"readLine()"方法的疑问…该如何处理

BufferedReader reader = ...;
ArrayList<String> list = new ArrayList<String>();
String line = null;
while((line = reader.readLine())!=null){
    list.add(line);
}
//all lines in list

------解决方案--------------------
再稍微补充下 
 [code=Java] 
 BufferedReader bufr = new BufferedReader(new InputStreamReader( 
 	new FileInputStream( "e:\\upload\\doc.txt "), "gbk ")); 
         String line = null; 
         ArrayList <String>  list = new ArrayList <String> (); 
 	while((line=bufr.readLine())!=null){ 
         list.add(line); 
 }[/code]
