java catch process time real time progress bar

new Scanner(new URL("SOME_URL.txt").openStream(), "UTF-8").useDelimiter("\\A").next();
Using this ^ I get the data from a .txt-File which I save in a String.
For my progress bar, I wondered if it would be possible for jobs like that (or in general for methods etc.) to count (or sth. like that) the time it needed to be finished. So that I can show in real time process time in my bar.
Is this somehow possible?

Is it possible? Yes. Is it possible when using Scanner.next() to read the contents of the URL? No.
You will need to read the bytes yourself, and count them:
URL url = new URL("SOME_URL.txt");
URLConnection conn = url.openConnection();
ByteBuffer buffer = ByteBuffer.allocate(conn.getContentLength());
EventQueue.invokeLater(() -> progressBar.setMaximum(buffer.limit()));
EventQueue.invokeLater(() -> progressBar.setValue(0));
try (ReadableByteChannel channel = Channels.newChannel(conn.getInputStream())) {
while (channel.read(buffer) >= 0) {
EventQueue.invokeLater(() -> progressBar.setValue(buffer.position()));
}
}
buffer.flip();
String rawG = StandardCharsets.UTF_8.decode(buffer).toString();

NotFoundException even when a barcode is in the picture

I am trying to make a simple barcode scanner project for fun. And I've run into a slight problem. I am using zXing and Webcam Capture for this.
Even if a Barcode is present in the picture, Java keeps telling me none is found through the NotFoundException. I look for a frame every time webcamImageObtained is run (which I assume is every frame?) and then I look for a barcode in the frame that I captured.
I took this picture with that webcam (Ironically using the code hah):
When I hover over this barcode it reports about 30 images per second and otherwise about 7-8 when it looks at me from my screen (if that means anything).
Whenever I find a code, I want to add it to a JList (not accounting for duplicates and the likes yet).
I call this code every time webcamImageObtained(WebcamEvent we) fires:
#Override
public void webcamImageObtained(WebcamEvent we) {
BufferedImage myImage;
try {
myImage = webcam.getImage();
LuminanceSource source = new BufferedImageLuminanceSource(myImage);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Result result = reader.decode(bitmap);
DefaultListModel dlm = (DefaultListModel) list.getModel();
dlm.addElement(result.toString());
list.setModel(dlm);
} catch (NotFoundException ex) {
Logger.getLogger(AdvancedWebcamPanelExample.class.getName()).log(Level.SEVERE, null, ex);
} catch (ChecksumException ex) {
Logger.getLogger(AdvancedWebcamPanelExample.class.getName()).log(Level.SEVERE, null, ex);

Am I missing something about how this library scans for a barcode?
EDIT
Not sure this helps much..
Mar 02, 2015 10:04:34 PM sandbox_webcam.AdvancedWebcamPanelExample webcamImageObtained
SEVERE: null
com.google.zxing.NotFoundException
Throws exception here:
Result result = reader.decode(bitmap);

There is a different question which has some available answers: Android zxing NotFoundException
As James said, it is a good idea to try with bar codes on different media (paper/screen) if it is not working, and in different circumstances and lighting conditions. Particularly ensure that you have enough light, and that the FPS of the camera is high enough while it is pointed at the barcode.
For debugging, one could also convert the BinaryImage back into a viewable format and check whether the barcode is actually visible after conversion to black-and-white.

Java Authentication Program Issue

I am new to programming, and created a little program to practice code. It is an authentication program where you type in a username and password, and only my specified username and password will work to make it show a picture. I typed all the code, and there was no error; but when I ran it and typed in the username and password, it failed to show the picture. Here is my code.

You never call your test method from your implementation of actionPerformed(). Here's a much simplified version of your program that checks username when you click on TestAccess.

Java Metal Look & Feel hides Windows toolbar when maximized

In my application we use CrossPlatform L&F (metal) and we want to launch the main JFrame maximized. When executing I find the windows toolbar hidden. This does not happen if I use System L&F.
Why is this so? Is there any way to avoid this?
Code excerpt to force Metal L&F is:
try {
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
MetalLookAndFeel.setCurrentTheme(new OceanTheme());
UIManager.setLookAndFeel(new MetalLookAndFeel());
} catch (ClassNotFoundException ex) {
code to catch this exception;
} catch (InstantiationException ex) {
code to catch this exception;
} catch (IllegalAccessException ex) {
code to catch this exception;
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
code to catch this exception;
}
JFrame.setDefaultLookAndFeelDecorated(Boolean.TRUE);
and method to maximize window is as follows:
private void formWindowOpened(java.awt.event.WindowEvent evt) {
setExtendedState(JFrame.MAXIMIZED_BOTH);
return;
}
Many Thanks in advance

It seems that it is a known issue when you call:
JFrame.setDefaultLookAndFeelDecorated(Boolean.TRUE);
See this link: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4737788
It also shows a workaround by subclassing JFrame and return appropriate maximum bounds. Here is a demo code of this workaround:

final JFrame frame = new JFrame(TestJFrame.class.getSimpleName()) {
private Rectangle maxBounds;
#Override
public Rectangle getMaximizedBounds() {
return maxBounds;
}
#Override
public synchronized void setMaximizedBounds(Rectangle maxBounds) {
this.maxBounds = maxBounds;
super.setMaximizedBounds(maxBounds);
}
#Override
public synchronized void setExtendedState(int state) {
if (maxBounds == null && (state & Frame.MAXIMIZED_BOTH) == Frame.MAXIMIZED_BOTH) {
Insets screenInsets = getToolkit().getScreenInsets(getGraphicsConfiguration());
Rectangle screenSize = getGraphicsConfiguration().getBounds();
Rectangle maxBounds = new Rectangle(screenInsets.left + screenSize.x, screenInsets.top + screenSize.y, screenSize.x
+ screenSize.width - screenInsets.right - screenInsets.left, screenSize.y + screenSize.height
- screenInsets.bottom - screenInsets.top);
super.setMaximizedBounds(maxBounds);
}
super.setExtendedState(state);
}
};
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.addWindowListener(new WindowAdapter() {
#Override
public void windowOpened(WindowEvent e) {
frame.setExtendedState(frame.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}
});
JLabel label = new JLabel("some label in the middle");
label.setHorizontalAlignment(JLabel.CENTER);
frame.add(label);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
MetalLookAndFeel.setCurrentTheme(new OceanTheme());
UIManager.setLookAndFeel(new MetalLookAndFeel());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block

}
JFrame.setDefaultLookAndFeelDecorated(Boolean.TRUE);
SwingUtilities.invokeLater(new Runnable() {

}
Alternatively, don't call JFrame.setDefaultLookAndFeelDecorated(Boolean.TRUE);

Captured webcam image not refreshing and max size too big to show

I am having some problems with my program. I have a GUI that shows a live image from a webcam (using [jvacv][1]) in one side, and the captured image in the other. To capture the image, I have a button. One problem is that the captured image is refreshing only if I close and open the program again. The other is that I want to capture a 1080p image from webcam, but live image at 640x480.
