How to make when i click JButton to make it doubling output. For ex i click jButton once, but i want to output 2

I'm trying to make cookie clicker game and i'm at point where i want to program upgrades, for ex: when i buy first upgrade i want if i click once to get 2 cookies, before upgrade it was if i click once i get only 1 cookie. I'm not sure how to code that and also in the future i want to code even more upgrades. What i'm asking to someone help me to make peace of code that can be used to make clicking upgrades.

public class JavaApplication13 {
public static void main(String[] args) {
DBP prozor = new DBP();
prozor.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
prozor.setVisible(true);
}
}
class DBP extends JFrame {
private JLabel oznaka;
public DBP() {
setTitle("Cookie Clicker");
setSize(500, 150);
setLayout(new FlowLayout(FlowLayout.CENTER, 30, 20));
oznaka = new JLabel("No points!");
add(oznaka);
JButton dugme = new JButton("Click");
add(dugme);
JButton upgrade = new JButton("Buy upgrade!");
add(upgrade);
upgrade.setVisible(false);
dugme.addActionListener(new ActionListener() {
private int brojac;
#Override
public void actionPerformed(ActionEvent e) {
brojac++;
oznaka.setText("Points " + brojac);
if (brojac == 5) {
upgrade.setVisible(true);
}
}
});
upgrade.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
upgrade.setVisible(false);
System.out.println("SA");
}
});
}
}

The simplest way to do it, is to keep a boolean value if the user has clicked the upgrade button. If he did, increase "cookies" one more time.
public class JavaApplication13 {
public static void main(String[] args) {
// All swing applications must run on their own thread.
SwingUtilities.invokeLater(() -> {
DBP prozor = new DBP();
prozor.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
prozor.setVisible(true);
});
}
}
class DBP extends JFrame {
private JLabel oznaka;
private boolean upgraded; //whether user upgraded
public DBP() {
setTitle("Cookie Clicker");
setSize(500, 150);
setLayout(new FlowLayout(FlowLayout.CENTER, 30, 20));
oznaka = new JLabel("No points!");
add(oznaka);
JButton dugme = new JButton("Click");
add(dugme);
JButton upgrade = new JButton("Buy upgrade!");
add(upgrade);
upgrade.setVisible(false);
dugme.addActionListener(new ActionListener() {
private int brojac;
#Override
public void actionPerformed(ActionEvent e) {
brojac++;
if (upgraded)
brojac++;
oznaka.setText("Points " + brojac);
if (brojac == 5) {
upgrade.setVisible(true);
}
}
});
upgrade.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
upgrade.setVisible(false);
upgraded = true;
}
});
}
}

How to Change Default Inputs for JComboBox and JButton

How do I make the Enter key trigger a JComboBox or JButton in a GUI rather than having to hit the Space key? I have an assortment of text fields and check boxes with buttons and combo boxes in between. I'd like to avoid having to switch between hitting space and enter and rather only have to hit enter for all components.
package koning.personal.dungeonsanddragons;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class test {
JFrame window = new JFrame("testGUI");
JPanel windowPanel = new JPanel();
public static JLabel labelSize;
public static JComboBox<String> comboSize;
public static JLabel labelButton;
public static JButton buttonButton;
public test () {
super();
labelSize = new JLabel("Monster Size:");
String[] sizeChoices = { "None", "Tiny", "Small", "Medium", "Large", "Huge", "Colossal"};
comboSize = new JComboBox<String>(sizeChoices);
comboSize.setToolTipText("The creature's size.");
labelButton = new JLabel("Button:");
buttonButton = new JButton();
windowPanel.setLayout(new FlowLayout());
windowPanel.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT);
windowPanel.add(labelSize);
windowPanel.add(comboSize);
windowPanel.add(labelButton);
windowPanel.add(buttonButton);
windowPanel.setVisible(true);
window.setSize(500, 500);
window.setLayout(new FlowLayout());
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setVisible(true);
window.add(windowPanel);
comboSize.addActionListener(handler);
buttonButton.addActionListener(handler);
}
ActionHandler handler = new ActionHandler();
public class ActionHandler implements ActionListener {
public void actionPerformed(ActionEvent eventFocus){
if (eventFocus.getSource() == comboSize){
buttonButton.requestFocusInWindow();
}
if (eventFocus.getSource() == buttonButton){
comboSize.requestFocusInWindow();
}
}
}

public static void main(String[] args) {
test GUITest = new test();
}
}

You can add a KeyListener and execute doClick
JButton btn = new JButton();
btn.addKeyListener(new KeyListener() {
#Override
public void keyTyped(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_ENTER)
btn.doClick();
}
#Override
public void keyReleased(KeyEvent e) {
// TODO Auto-generated method stub
}
#Override
public void keyPressed(KeyEvent e) {
// TODO Auto-generated method stub
}
});

If the goal is to have something happen when the enter button is pressed (pressed once and something happens with all the components) then you can add a KeyListener to the JFrame:
JFrame frame = new JFrame("Examplpe");
//here you create and add the components to the frame
and then you can add a KeyListener:
frame.addKeyListener(new KeyListener(
#Override
public void keyTyped(KeyEvent e) {
if(e.getKeyCode == KeyEvent.VK_ENTER){//this is the if block I'm refering to in the following explanation
//do something with all the components
}
}
#Override
public void keyReleased(KeyEvent e) {}
#Override
public void keyPressed(KeyEvent e) {}
}
and then when you press Enter, the code inside the if block will be executed.
Hope this helps :)

Update a custom JLabel in all frames

I have a instance of a custom JLabel and i want to changes its text in all frames, but the text is changing only on the last opened frame. There's a way i can achieve this?

And my code:

}
public MyCustomLabel getMyCustomLabel() {

I have a instance of a custom JLabel and i want to changes its text in all frames,
A Swing component can only have a single parent. So you actually have two instances of your custom label. So updating the text in one label does not affect the other.
What you can do is create a PlainDocument to contain the text to be shared by multiple JTextFields. Then when the text is the Document is changed all the text fields will be updated.
So in the App class you would have:
private PlainDocument sharedDocument = new PlainDocument();
and you would create a method to access the Document. Maybe something like getSharedDocument().
Then in the form classes you would do something like:
//add(App.getApp().getMyCustomLabel());
JTextField textField = new JTextField( App.getApp().getSharedDocument() );
// customize text field to look like a label
textField.setBorder( null );
textField.setEditable( false );
add( textField );

ActionListener is only counting left mouse click

I learned this code from some tutorial but it only counts left mouse clicks. I try with MouseListener but it kept counting while the timer came to 0. And with ActionListener it isn't counting the right mouse clicks. Any suggestions? Maybe its a foolish question but I'm new here.

Use this it will let you see right mouse clicks

}

Pressing Enter to Continue

I have a JDialog which has two fields, username and password. I want to make the form like normal ones in which pressing enter will be like pressing continue.
I have already tried getRootPane().setDefaultButton(myButton);, but only that does not seem to work.

I have already tried getRootPane().setDefaultButton(myButton);, but only that does not seem to work.
than you have to invoke code for this button with method
JButton#doClick();
but better would be use KeyBindings

JButton button = ...
JTextField password = ...
ActionListener buttonListener = ...
button.addActionListner(buttonListener);
password.addActionListener(buttonListener);
When enter is pressed in a JTextField, an action event is fired.

You can achieve this by adding an action listener to your textfield, like so.
JTextField field1 = new JTextField();
field1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//here is your method to continue
continue();
}
});
