Answer 1

In main() when you coded Thread.sleep(..) you wanted main thread to sleep so your xmitt could run. I think you can leave it as it is even with your terminating button.
I do not want to critisize but it looks like your concept is wrong. Usually this kind of program have kind of diffrent design. Not going into details like this:
class Xmitt implements Runnable {
volatile boolean keepRunning;
other members ....
public void run() {
transmit();
public void transmit() {
keepRunning = true;
while(keepRunning) {
try{...}
catch{}
public void stopTransmitting() {
keepRunning = false;
//maybe Thread.currentThread().interrupt() or stop() //which is deprecated
public class TransTest extends JPanel {
Xmitt xmitt;
JButton start;
JButton stop;
public TransTest() {
add buttons with actionlisteners:
if(startbutton) {
Thread xmittthread = new Thread(xmitt);
xmittthread.start();
if(stopbutton) {
xmitt.stopTransmitting();
public static void main(String[] args) {
TransTest tt = new TransTest();
JFrame f = new JFrame("Transmitter");
f.setContentPane(tt);
f.setSize(..);
f.setVisible();
System.exit(0);
You can use other methods then boolean to stop if there are i/o operations which can be tough to interrut.
Anyway, to implement this program nicely, you need to learn more about threads, it's not that easy.
Happy transmitting!
