'Try without catch error'，')' 预期，表达式的非法开始..？

Question

我在下面代码的结尾花括号中遇到了这些错误。有人能告诉我为什么会出现这些错误吗？我以为代码应该以大括号结尾。

      String line = "";
                    while ((line = reader.readLine()) != null) {
                        buffer.append(line);
                    }

                    movieData.setText(buffer.toString());

                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    //will check if connection is running or not and will disconnect accordingly
                    if (connection != null) {
                        connection.disconnect();
                    }
                    try {
                        try {
                            reader.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }

您忘记在末尾添加catch 块:

try {
    try {
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
catch (Exception e) { // Add catch block to handle potential exception
    e.printStackTrace();
}

（考虑到您在 String line = ""; 之前以 try 块开始）

'Try without catch error', ')' expected, illegal start of expression..?

android

try-catch
