来自Com端口的Java readLine

有没有办法将这个java代码（从com端口读取）更改为读取行
例如

我正在使用rxtx com

原始方法：

public void serialEvent(SerialPortEvent event) {
    switch (event.getEventType()) {
        case SerialPortEvent.DATA_AVAILABLE:
            byte[] readBuffer = new byte[10];
            int numBytes = 0;
            try {
                while (inputStream.available() > 0) {                       
                    numBytes = inputStream.read(readBuffer);
                }
            } catch (IOException e) {
                System.out.println(e);
            }
        System.out.println(Arrays.toString(readBuffer));
    }
}

假设

inputStream

是一个

inputStream

，您可以用一个和一个（有一个）来包装它。大概

case SerialPortEvent.DATA_AVAILABLE:
  String line;
  BufferedReader br = null;
  try {
    br = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
    while ((line = br.readLine()) != null) {
      System.out.println(line);
    }
  } catch (IOException e) {
    e.printStackTrace();
  } finally {
    try {
      br.close();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

或者你可以用

您可以使用一个缓冲的inputstream来包装读取器，读取器可以包装您的inputstream。。。类似于BufferedReader br=新的BufferedReader（新的InputStreamReader（即“UTF-8”）；（其中“is”是您的输入流。请阅读Java IO

case SerialPortEvent.DATA_AVAILABLE:
  String line;
  BufferedReader br = null;
  try (br = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));) {
    while ((line = br.readLine()) != null) {
      System.out.println(line);
    }
  } catch (IOException e) {
    e.printStackTrace();
  }
