读文本文件

一段读取文本文件的例子

 

File f = new File("D:\\info_fluxbill1.txt");   

InputStreamReader read = new InputStreamReader(new FileInputStream(f), "UTF-8");   
BufferedReader reader = new BufferedReader(read);   
String line = null;
while ((line = reader.readLine()) != null) {   
	if("".equals(line)) {   
		continue;   
	}   
}

弱弱的问句

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

为什么不写成!=-1呢

</div>
 

我又修改了一下代码，line是字符串，自然不能用-1去比较

？這種例子網上很多啊，各種文檔格式的各種讀法的

去年工作中碰到了要读一个文件，从网上查到后就记录下来了，呵呵
