Java Write serial port

Java host computer to the microcontroller to write serial instructions, the simple code is as follows:

Import java.io.inputstream;import java.io.outputstream;import javax.comm.*;p ublic class Test {public     static void Main (String args[]) throws Exception    {        Commportidentifier Serialportid = Commportidentifier.getportidentifier ("COM3");           SerialPort  port = (SerialPort) serialportid.open ("Read", +);          Open the COM3 serial port, where 30 is the timeout time to open the serial port          port.setserialportparams (9600, 8, 1, 0);//Set COM2 baud rate, data bit, stop bit, check mode          // Get input output stream from the string         byte[] buffer = {0x0f,0x01,0x00};//controlling command        outputstream out = Port.getoutputstream ( );           Out. write (buffer);            Out. Flush ();           InputStream in = Port.getinputstream ();           In.read (data); Data is a byte[]    }}
