Is there any way to call public method of a child thread from its parent class

public class Lettore implements Runnable {

    SerialPort port;

    public Lettore(SerialPort port) throws IOException {
        this.port = port;

    @Override
    public void run() {

                len = port.getInputStream().read(buffer);
                System.out.print(new String(buffer, 0, len));
