错误消息：流关闭

错误消息：流关闭 问题

问题是

br.close()

，按照javadoc的说明，您执行了该 *** 作，将关闭流 并释放与之关联的所有系统资源 。

为了快速验证，请注释掉：

if (br != null) {//    try {//        br.close();//    } catch (IOException e) {//        // TODO Auto-generated catch block//        e.printStackTrace();//    }}

您可以

s

随时随地回答，没有任何例外。

一个办法

一种解决方案是在所有读取终止后关闭缓冲区读取器：

    String moreSearch = null;    InputStreamReader isr = new InputStreamReader(System.in);    BufferedReader br = new BufferedReader(isr);    try {        do { // ... System.out.println("More Flight Query ? Press n/N to exit. Anyother key to continue searching."); moreSearch = br.readLine();        } while (!moreSearch.equalsIgnoreCase("n"));    } catch (IOException e) {        Logger.getLogger(FlightSearch.class.getName()).log(Level.SEVERE, "Cant read line from a System.in based BufferedReader", e);    } finally {        if (br != null) { try {     br.close(); } catch (IOException ignoreMe) {     Logger.getLogger(FlightSearch.class.getName()).log(Level.SEVERE, "Can't close a System.in based BufferedReader", ignoreMe); }        }    }
