I really need help with this. I have been having problems resizing the gameBoardPanel JPanel that is added the the main Panel. Everything I have tried including resizing it has not helped, I basically want to add the gameBoardPanel at 400x400 to the main panel (which is 400x500), leaving me 400x100 of space for other buttons e.x return to menu, etc. Any help would be much appreciated!
Thanks!

It's really hard to understand what you want to achieve. You want to make room to which buttons at the bottom?? How is the screen supposed to look like?
Anyway, i think you should use different panels and layoutmanagers to solve your problem, and what I think can help you best is the BorderLayout.
If you want your gameBoardPanel to fully fit the window when the game starts, you could change your code to something like this at the end of your startUp() method:
//Switch panels from start panel to main panel
main = new JPanel(new BorderLayout());
menuPanel.setVisible(false);
remove(menuPanel);
main.add(gameBoardPanel, BorderLayout.CENTER);
JPanel buttonsPanel = new JPanel();
buttonsPanel.setPreferredSize(new Dimension(400, 100));
main.add(buttonsPanel, BorderLayout.SOUTH);
From looking at your code it is obvious you haven't read the layout manager tutorials. From your description you almost certainly want to use BorderLayout, put your game panel in CENTER and your button panel in SOUTH.
The component in CENTER position gets all left over space and the component in SOUTH gets its preferred height honored, but takes all available width.

I have a half-working paint/turtle graphics program but I am having a few issues.
I am going to need to save the image that is drawn at some point - I know I need to use a BufferedImage but how do I go about this? I have attached a little bit of my code below.
In short I have a JFrame with a text field and a white JPanel below it. When commands are typed in by the user lines are drawing through another class and appear on the JPanel. I know I won't be able to save them off the JPanel to an image but have no understanding of how to implement a buffered image and what i would/wouldn't need to change.
Please be kind, I am new to programming and haven't finished some parts of my code yet.
Thanks in advance

//commands from text
//add the command line textfeild to the interface
panel.add(text);
//uses border layout to set the layout of the interface

}
I would keep an array of all your lines, then iterate through them, and then use img.createGraphics() to draw your lines and other graphics.
Recently I have been trying to get a transparent JFrame without success.
I want to make all components visible but not the frame and I see that people set the background to transparent and set Opaque to false.
I am doing this but without success.

You've made a nice attempt, but try this instead.
// Apply a transparent colour
setBackground(new Color(0, 255, 0, 0));
Simply add that code and your done :)
I set the background to frame.setBackground(new Color(0, 0, 0, 0)); thanks to the help of #JontyMorris
I then set all the contents on the frame to opaque panel.setOpaque(false);
and removed the backgrounds I set so the stripped down version looks like this...
// Frame
JFrame frame = new JFrame();
frame.setBackground(new Color(0, 0, 0, 0)); // Setting frame to be transparent
// Components
JPanel panel = new JPanel();
//add stuff to panel...
panel.setOpaque(false);
Actually there's a bit more to it than setting the background color. You have to change the undecorated property to true. Here's a quick tutorial you can follow. Well explained.

I am working on a small example using Java Swing where I want to draw a sine graph on one panel and the co-ordinates of the graph in another panel. So I created a class that extends the JFrame then I created the JPanel for graph and co-ordinates. For displaying co-ordinates I am using JList. Now the problem is the co-ordinates are showing duplicate values. Here is my code:
public class MyFrame extends JFrame {
JList list;
DecimalFormat df = new DecimalFormat("#.###");
DefaultListModel model = new DefaultListModel();
private JPanel contentPane;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MyFrame frame = new MyFrame();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public MyFrame() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 600, 600);
contentPane = new JPanel();
contentPane.setBorder(new LineBorder(new Color(0, 0, 0)));
setContentPane(contentPane);
contentPane.setLayout(new GridLayout(1, 2, 0, 0));
JPanel panel = new MyGraph();
panel.setBorder(new LineBorder(new Color(0, 0, 0)));
contentPane.add(panel);
list = new JList(model);
list.setVisibleRowCount(4);
JPanel panel_1 = new JPanel();
panel_1.setBorder(new LineBorder(new Color(0, 0, 0)));
panel_1.setLayout(new BoxLayout(panel_1, BoxLayout.Y_AXIS));
JLabel lblNewLabel_1 = new JLabel("X - Y");
panel_1.add(lblNewLabel_1);
JScrollPane slistScroller = new JScrollPane(list);
panel_1.add(slistScroller);
contentPane.add(panel_1);
}
class MyGraph extends JPanel {
public void paintComponent(Graphics g) {
super.paintComponent(g);
int xBase = 10;
int top = 100;
int yScale = 10;
int xAxis = 360;
int yBase = top + yScale;
g.drawLine(xBase, top, xBase, top + 2 * yScale);
g.drawLine(xBase, yBase, xBase + xAxis, yBase);
g.setColor(Color.red);
int x2=0, y2=0;
int x1 = xBase + 0;
int y1 = yBase - (int) (10*Math.sin(0) * yScale);
int i;
for (i = 0; i < 10; i++) {
x2 = xBase + i;
y2 = yBase - (int) (10*Math.sin(i) * yScale);
g.drawLine(x1, y1, x2, y2);
x1 = x2;
y1 = y2;
df = new DecimalFormat("#.###");
model.addElement(i +" -- " + df.format(10*Math.sin(i)));
}
model.addElement("------END----------");
}
}
}
Here is the output of my program:
As per my program, I have a for loop from angles 0 to 10 and I am adding the values to DefaultListModel model which is added to JList list.
Can someone please help me where I am doing mistake in this code?
Also even when I have this line list.setVisibleRowCount(4); , I was expecting only 4 records displayed to the user with a scroll-bar, but as per the output image it is not working like that.
paintComponent may be any number of times, for any number of reasons, try resizing the frame and see what happens.
Your paint method should focus on doing just that, painting.
You need to change the process so that the paintComponent becomes depend on the model, not the other way round.
Take a look at Painting in AWT and Swing for more details about painting in Swing.
You may also want to consider using a ListCellRender to render the data in the model in the JList, this way, you could more easily share the model and it's data.
See Writing a Custom Cell Renderer for more details
I have an assignment in my CS12 class, which to create a program where can be combined JRadioButon/JCheckBox/JComboBox all together.
As of now I am very confused with JComboBox, I don't understand what exactly am i missing in an ActionListener part.
First I can't choose any option from the third column( Colour & Interior ), it is simply doesn't shows up on the label created in the same column.
Second, I can't see the values of the JCheckBoxes created in the second column, before I chose the province from the fourth column.
Will accept any advise, thank you.

This....
Is why you should use appropriate layout managers...
As to your problems...
You keep getting a NullPointerException because (as far as I've been able to test it), m and k are null...
You're using a single instance of an ItemListener listener for all your controls (that accept them), this is a really bad idea as it makes it difficult to determine 1- the current state and 2- what caused the event...
Personally, I prefer to use separate listeners where I can, so I can isolate exactly what is going on...
If you change m and k to be double instead of Double, this will solve the immediate issue
The next issue you will have is with the comparison of the values from the combo box...
In you event handler, you are using if (one.equals("Passion Red")) { to check the color option, but the actual entry is Passion Red [add $200.00], meaning that it will never match...
I presume you have a number of these types of issues, so you're going to have to dig through your code to find them all...
