Java Settings Menu

I am curently working on a GUI and when clicking a certain button:
settingsB.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
System.out.println("Settings");
}
});
Instead of just printing it there should a new window open where you can adjust settings with sliders textboxes, ... How would you approach that? With new classes or all inside the action listener?
Edit:
My "current solution" is based on the great suggestion from user Holger to call a method showSettingsDialogue():
private void showSettingsDialogue() {
if(settingsOpen) {
return;
}
else {
settingsOpen = true;
settingWindow = new SettingsWindow();
settingWindow.addWindowListener(new WindowListener() {
#Override
public void windowOpened(WindowEvent e) {
// TODO Auto-generated method stub
}
#Override
public void windowIconified(WindowEvent e) {
// TODO Auto-generated method stub
}
#Override
public void windowDeiconified(WindowEvent e) {
// TODO Auto-generated method stub
}
#Override
public void windowDeactivated(WindowEvent e) {
// TODO Auto-generated method stub
}
#Override
public void windowClosing(WindowEvent e) {
// TODO Auto-generated method stub
}
#Override
public void windowClosed(WindowEvent e) {
settingsOpen = false;
}
#Override
public void windowActivated(WindowEvent e) {
// TODO Auto-generated method stub
}
});
}
Unfortunally with this way I have to write down even unimplemented methods. Any bether solution then this?

GamesStatusCodes, Status 6, STATUS_NETWORK_ERROR_OPERATION_FAILED

Hello guys,
I have been trying to implement google play services with LibGDX and am trying to create a Quickgame() where everyone is auto matched. However, on the public void onRoomCreated(int arg0, Room arg1) method, the when i print out the status code, it keeps giving me 6.
I have tried several solutions but to no avail
Relinking the game and ensuring the SHA1 code is correct. (Sign in works correctly)
Checking my phones network status, it is connected to the internet.
Does anyone perhaps have a solution? Thank you!

Based on this documentation, you need to check if multiplayer support is enabled for your client ID. You need to enable real-time multiplayer support in the Developer Console. Check this link on how to enable multiplayer support.

WebSocket Connection for xmpp

I am trying to establish a websocket connection with port:5280,but unable to connect(server is not listening).
public static WebSocketClient cc;
public static void main(String[] args) throws URISyntaxException
{
cc=new WebSocketClient(new URI("ws://localhost:5280"))
{
#Override
public void onOpen(ServerHandshake arg0)
{
// TODO Auto-generated method stub
System.out.println("onOpen" +arg0);
}
#Override
public void onMessage(String arg0)
{
// TODO Auto-generated method stub
System.out.println("onMessage");
}
#Override
public void onError(Exception arg0)
{
// TODO Auto-generated method stub
System.out.println("onError");
}
#Override
public void onClose(int arg0, String arg1, boolean arg2)
{
// TODO Auto-generated method stub
System.out.println("onClose");
}
};
cc.connect();
Above one is working with new URI("ws://localhost:8887/8080/5120") but having some problem with port no-5280.
Give me any Fix??

how can understand that the DJ native swing jwebbrowser has been completely load the web page?

I want to execute my javascript code in DJ native swing jwebbrowser, but I should wait for the page loading, how can I set listener for it?
I try the following, but after loading it always run the script also it operate late!
webBrowser.addWebBrowserListener(new WebBrowserListener(){
#Override
public void commandReceived(WebBrowserCommandEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void loadingProgressChanged(WebBrowserEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void locationChangeCanceled(WebBrowserNavigationEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void locationChanged(WebBrowserNavigationEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void locationChanging(WebBrowserNavigationEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void statusChanged(WebBrowserEvent arg0) {
// TODO Auto-generated method stub
if(webBrowser.getLoadingProgress() == 100)
webBrowser.executeJavascript("some js code");");
}
#Override
public void titleChanged(WebBrowserEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void windowClosing(WebBrowserEvent arg0) {
// TODO Auto-generated method stub
frame.dispose();
}
#Override
public void windowOpening(WebBrowserWindowOpeningEvent arg0) {
// TODO Auto-generated method stub
}
#Override
public void windowWillOpen(WebBrowserWindowWillOpenEvent arg0) {
// TODO Auto-generated method stub
}
});
what should i do?

I should override loadingProgressChanged(WebBrowserEvent arg0) not statusChanged(WebBrowserEvent arg0)
#Override
public void loadingProgressChanged(WebBrowserEvent arg0) {
// TODO Auto-generated method stub
if(webBrowser.getLoadingProgress() == 100)
webBrowser.executeJavascript("some js code");
}
but still it takes time to load my html!

How to read data from finger print reader and convert into image file in java

i have to read data from finger print reader and convert into image file. I am using Digital Persona 's device U and U 4500 with Platinum SDK . I am new biometric field. Till now I am only able to detect the device means whether it is connected to system or not.Please guide me what should i do to accomplish this task
i have used this Code(only to check whether device is working )
import com.digitalpersona.onetouch.DPFPGlobal;
import com.digitalpersona.onetouch.DPFPSample;
import com.digitalpersona.onetouch.capture.DPFPCapture;
import com.digitalpersona.onetouch.capture.event.DPFPDataEvent;
import com.digitalpersona.onetouch.capture.event.DPFPDataListener;
import com.digitalpersona.onetouch.capture.event.DPFPErrorEvent;
import com.digitalpersona.onetouch.capture.event.DPFPErrorListener;
import com.digitalpersona.onetouch.capture.event.DPFPReaderStatusAdapter;
import com.digitalpersona.onetouch.capture.event.DPFPReaderStatusEvent;
import com.digitalpersona.onetouch.capture.event.DPFPReaderStatusListener;
import com.digitalpersona.onetouch.capture.event.DPFPSensorEvent;
import com.digitalpersona.onetouch.capture.event.DPFPSensorListener;
public class Demo {
public static void main(String args[]){
//byte[] a=null;
DPFPCapture capture=DPFPGlobal.getCaptureFactory().createCapture();
capture.addReaderStatusListener(new DPFPReaderStatusListener() {
#Override
public void readerDisconnected(DPFPReaderStatusEvent arg0) {
//TODO Auto-generated method stub
System.out.println("I m Dis-connected");
}
#Override
public void readerConnected(DPFPReaderStatusEvent arg0) {
// TODO Auto-generated method stub
System.out.println("I m connected");
}
});
capture.addSensorListener(new DPFPSensorListener() {
#Override
public void imageAcquired(DPFPSensorEvent arg0) {
// TODO Auto-generated method stub
System.out.print("acquired");
}
#Override
public void fingerTouched(DPFPSensorEvent arg0) {
// TODO Auto-generated method stub
System.out.print("s");
}
#Override
public void fingerGone(DPFPSensorEvent arg0) {
// TODO Auto-generated method stub
System.out.print("gone");
}
});
capture.startCapture();
capture.addDataListener(new DPFPDataListener() {
#Override
public void dataAcquired(DPFPDataEvent arg0) {
// TODO Auto-generated method stub
DPFPSample sample=DPFPGlobal.getSampleFactory().createSample();
sample=arg0.getSample();
byte a[]=sample.serialize();
for(byte i:a){
System.out.print(i);
}
}
});
capture.addErrorListener(new DPFPErrorListener() {
#Override
public void exceptionCaught(DPFPErrorEvent arg0) {
// TODO Auto-generated method stub
System.out.println("error");
}
#Override
public void errorOccured(DPFPErrorEvent arg0) {
// TODO Auto-generated method stub
System.out.println("error");
}
});
}
}

I am also currently working on a Digital Persona Finger Print Reader, I actually had the same Problem but now i have overcome it,
I think the code to add the Listeners should be in the init() method and also start the init method in the constructor of the class
The main method should only instantiate the Class.
