Okay so I have the choice of difficulty in a separate class, in the Menu class. The rows, columns, and bombs are sent into the GUI class through parameters, and in the GUI class implements MouseListener.

When I override the mouseClicked method of MouseListener how can I send in the variables rows, columns, and bombs? It gives me an error if I send more than just the parameter of (MouseEvent event).

The error is the GUI is not abstract and does not override abstract method mouseClicked. So can I not send in more than the default parameter?

This is what I'm trying to do...
public void mouseClicked(MouseEvent event, int rows, int columns)

you can't. that's not how it works.

the way UI code typically works is that you keep track of the difficulty (or rows/columns/bombs) in some form of a shared state (a class variable in the main handler or something), and on the mouse click event handler, you set those variables and call a reload() method on the entire UI (the reload method obviously wipes clean the UI and creates a new one based on the current values of the aforementioned shared state).

if this isn't how your UI code is currently designed... well, it ought to be.

okay thanks.

Now I had my grid working until I wanted to display the bombs remaining at the top.
I created a new panel and set the bombs remaining to a label then added the label to the panel by doing this

Code

bombPanel.add(Jbombs, BorderLayout.NORTH;

and now it displays the bomb count but only one button of the grid, right underneath it. Do I have to change something with the frame to accommodate another panel?

e/ Would I have to follow a pattern and set the grid to CENTER or something?

e2/ And I have no idea how to do what you said. This is my first real project if you haven't already noticed.

this is a question specific to JFrame and how to use it, so it's not something I know off the top of my head. Google it or read the documentation/API

Code

JButton easy = new JButton("EASY");
JButton medium = new JButton("MEDIUM");
JButton hard = new JButton("HARD");

easy.addMouseListener(this);
medium.addMouseListener(this);
hard.addMouseListener(this);

public void mouseClicked(MouseEvent e)
{
if (e.getSource() == easy)
{
rows = 10;
columns = 10;
bombs = 10;
frameX = 250;
frameY = 250;
}
else if (e.getSource() == medium)
{
rows = 16;
columns = 16;
bombs = 40;
frameX = 500;
frameY = 500;
}
else if (e.getSource() == hard)
{
rows = 16;
columns = 30;
bombs = 99;
frameX = 700;
frameY = 500;
}

So I changed it all around and now it can't find the variable "easy". Which is the first button. Where I instantiate the buttons and add the MouseListeners, that is all in the class's constructor. MouseListener is implemented and JFrame is extended.

Declare it outside of your method. Your scope is too narrow.
