【JAVA】IO流关闭顺序

总体可以认为是“先开后关”原则，原因是 IO 流的打开顺序是固定且层层依托的。

例子如下：

public static void main(String[] args) throws Exception {URL url = new URL("http://127.0.0.1:8080/test"); HttpURLConnection connection = (HttpURLConnection) url.openConnection();InputStream in = connection.getInputStream();InputStreamReader isr = new InputStreamReader(in);BufferedReader reader = new BufferedReader(isr);// ...reader.close();isr.close();in.close();}

End .
