I have data coming from a bluetooth device, the data is being stored in an inputstream. I am taking the data from the inputstream and generating a graphic with Jfreechart. Whenever I turn off the bluetooth device the data keeps coming from the inputstream and the graphic continues being generated.

I need the data and the graphic to stop when I turn off the bluetooth device.

I am using Java.

Every InputStream has a close() method that should do exactly what you need ... if you can detect that the device is turned off, that is.

The docs on this.

Reference link : Closing java InputStream

which resolved my problem too.

    Properties props = new Properties();
    InputStream fis = new FileInputStream("message.properties");
    try {
        props.load(fis);
        //omitted.
    } catch (Exception ex) {
        //omitted.
    } finally {
        try {
            fis.close();
            fis=null;
        } catch (IOException ioex) {
            //omitted.
        }

}
