Change the background in JFrame

I'm getting the Co-ordinates of the mouse on the window , I'm also changing the background color using KeyListner
Letter B for Black
W for White
G for green
.......
but when I change the background color , only the background of the label is changing and not the entire window ,what I need is to change the entire window and not just the label , any ideas why is that ?

if you want to change the background of your aplication, you have to change the background of the JPane that contains all your components, you are doing:
label.setBackground(Color.ORANGE);
which is okay if you want to change the background of the label, this is explicit on the instruction, i did some changes in your code, look at this:
public class mouseCrd extends JFrame {
public mouseCrd() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 650, 650);
setTitle("Mouse co-ordinates");
setVisible(true);
setResizable(false);
JPanel panel = new JPanel();
panel.setBounds(0, 0, 650, 650);
add(panel);
JLabel label = new JLabel(".................");
label.setFont(new Font("Tahoma", Font.BOLD, 30));
panel.add(label);
panel.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e){
label.setText("X = "+ e.getX()+" ; Y = "+e.getY());
}
});
addKeyListener(new KeyAdapter() {
#Override
public void keyReleased(KeyEvent e) {
super.keyReleased(e);
char keyPressed = e.getKeyChar();
if(keyPressed=='b')
{
System.out.println("B is pressed");
panel.setBackground(Color.BLACK);
}
else if(keyPressed=='w')
{
System.out.println("W is pressed");
panel.setBackground(Color.WHITE);
}
else if(keyPressed=='r')
{
System.out.println("R is pressed");
panel.setBackground(Color.RED);
}
else if(keyPressed=='o')
{
System.out.println("O is pressed");
panel.setBackground(Color.ORANGE);
}
else if(keyPressed=='g')
{
System.out.println("G is pressed");
panel.setBackground(Color.GREEN);
}
}
});
}
public static void main(String[] args){
new mouseCrd();
}
}
I removed the contentPane because it was useless an then in the key released, i just change the backgound of the panel JPane with the method setBackground(), and i removed the use of the KeyEvent constants because is easier to use chars

I know what you already get the needed answer, but I would like to recommend you the Oracle Documentation regarding Swing and GUI's.
Its begginer friendly 😁 and it stress exactly what you need to know to have good fundaments.

Dispose() only working once

My problem is that I have a class that when the user types out the text displayed dispose() is called, which works the first time but if you don't close the program and open it again, dispose() is called, but doesn't do anything which breaks the program.
public class TypeMenu extends JDialog {

try {
Easy dialog = new Easy();
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
dialog.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* Create the dialog.
* #param introTxtField2
* #param textField2
* #param inputTxtField2
*/
public TypeMenu(JTextField inputTxtField2, JTextField introTxtField2, JTextField textField2) {
setBounds(100, 100, 450, 300);
getContentPane().setLayout(new BorderLayout());
contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));
getContentPane().add(contentPanel, BorderLayout.CENTER);

}

inputTxtField.setHorizontalAlignment(SwingConstants.CENTER);
inputTxtField.addKeyListener(new KeyAdapter() {

textField.setText(strField.substring(1));
System.out.println(length);
System.out.println(strField);
if (length - 1 <= 0) {
dispose();
}
} else {

}
}
});

your text field is static so he will have only one instance across the application.
so in the method getIntroTxtField() you have if statement that says :
if (introTxtField == null)
in the first time this condition is true but when you create the new instance this condition is false because the instance of the static field is all ready created in the first and you are adding the key listener inside the condition
so the action listener will be added only in the first creation.
if you need to keep the static because you need in other class you need to remove the == null
protected JTextField getInputTxtField() {
inputTxtField = null;
{
inputTxtField = new JTextField();
inputTxtField.setHorizontalAlignment(SwingConstants.CENTER);
inputTxtField.addKeyListener(new KeyAdapter() {
#Override
public void keyReleased(KeyEvent arg0) {
String strField = textField.getText();
char key = arg0.getKeyChar();
int length = strField.length();
if (Character.toLowerCase(strField.charAt(0)) == Character.toLowerCase(key)) {
inputTxtField.setText(" ");
textField.setText(strField.substring(1));
System.out.println(length);
System.out.println(strField);
if (length - 1 <= 0) {
dispose();
}
} else {
inputTxtField.setText(" ");
}
}
});
inputTxtField.setBounds(56, 177, 314, 40);
inputTxtField.setColumns(10);
}
return inputTxtField;
}
or remove the static from you field declaration static is used in
shared instace only when you are using only one instace across the
application like sessionFactory or any thing that need to be created
only one time.

you code is a lot to read but i think your problem is that you are calling the dispose() of the wrong object. may you are calling it always for the first object and you are creating a new one, and the dispose of this new dialog will never be call,Check you code may be you are creating many object and the dispose() is not called at all. make sure that you have full control of your objects instance to know if you are diposing the wanted dialog.

Java- disable buttons on one jpanel with another.

So my goal is to disable buttons on lets say panel B depending one what button they press on panel A. so below I have 2 combo boxes that id like to be able to enable or disable base on the buttons pressed on the first panel. Ive tried googling this problem but I'm new to java so its pretty rough going so far.
heres my sample code of what I'm trying to do.

replace your code with this one. Its working Fine. Hope you are expecting this thing.

Eclipse Why Does It Create An Extra Window

I'm trying to make a launcher. It works fine, except that when I press the 'Options' button it makes a little window in the corner. How do I prevent this?
The Launcher picture:

And now with the option frame running:

You can see the little window in the corner. It does not disappear when the Option frame does.

In your OptionsButton.addActionListener (pretty bad name for a variable, should not start with a capital letter), you create a Working object that IS a JFrame, and it's showed up.
But, in your Working class (realy bad name), that extends JFrame you work and show a final JFrame frame attribute.
That's why there is two windows (JFrame) showing up.
Delete that final JFrame frame in Working, and just use this !

Unresponsive JTextField

In my application I need to get a response between 1 and 9 from the user. I am using a JTextField to get the input. However when a button is pressed the user the JTextField becomes unresponsive. Here is a stripped down example of the problem:
import java.awt.EventQueue;
import java.awt.Font;
import java.awt.event.*;
import javax.swing.*;
public class InputTest {
private JTextField inputBox;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
new InputTest();
}
});
} // end main()
public InputTest() { // constructor
JFrame f = new JFrame("Input Test");
f.setBounds(100, 100, 450, 300);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLayout(null);
JLabel label = new JLabel("Enter an integer:");
label.setFont(new Font("Tahoma", Font.PLAIN, 14));
label.setBounds(109, 120, 109, 30);
f.add(label);
inputBox = new JTextField();
inputBox.setBounds(259, 120, 30, 30);
f.add(inputBox);
JButton button = new JButton("Button");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("Button Pressed");
}
});
button.setMnemonic('B');
button.setBounds(166, 198, 78, 23);
f.add(button);
f.setVisible(true);
inputBox.addKeyListener(new KeyAdapter() {
public void keyTyped(KeyEvent e) {
char c = e.getKeyChar();
if (c < '!' || e.getModifiers() > 0)
return;
if (c < '1' || c > '9') {
JOptionPane.showMessageDialog(null, c
+ " is not an integer");
// inputBox.setText("error");
System.out.println("You typed a non-integer");
} else
System.out.println("You typed " + c);
inputBox.setText(null);
}
});
} // end constructor
} // end class

You should almost never use a KeyListener with a Swing JTextComponent such as a JTextField, for example what happens when the user tries to copy and paste in their input? Instead consider using either a JFormattedTextField, or a JTextField with a DocumentFilter, or my choice -- a JSpinner.
import java.awt.event.ActionEvent;
import javax.swing.*;
public class InputTest2 extends JPanel {
private JSpinner spinner = new JSpinner(new SpinnerNumberModel(1, 1, 9, 1));
private JButton getSelectionButton = new JButton(new GetSelectionAction("Get Selection"));
public InputTest2() {
add(spinner);
add(getSelectionButton);
}
private static void createAndShowGui() {
InputTest2 mainPanel = new InputTest2();
JFrame frame = new JFrame("InputTest2");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
private class GetSelectionAction extends AbstractAction {
public GetSelectionAction(String name) {
super(name);
}
#Override
public void actionPerformed(ActionEvent evt) {
int value = ((Integer)spinner.getValue()).intValue();
System.out.println("You've selected " + value);
}
}
}
