I'm attempting to build Minesweeper in Java (Using Eclipse, if that matters for any reason whatsoever) and while making it, I've encountered an issue I haven't had before.
The window that's supposed to show up whenever a mine is pressed is opened... A lot. The window is only meant to open once and prompt the user to either continue or give up.
Important to note this only occurs whenever a mine is pressed on the top row of buttons. Not entirely sure if this is important, but the amount of times a window pops-up is 11. There are also no error codes given.
The following chunk of code is for whenever a user clicks on a mine.
//These are here just for clarification
private int continues = 3;
private Listen l = new Listen();
private class Listen extends MouseAdapter implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();
for (int i = 0; i < 9; i++)
{
for (int j = 0; j < 9; j++)
{
if (source == mines[i][j])
{
//Though probably not optimal, I created mines based around a number referred to as difficulty
if (minePlacement[i][j] <= difficulty)
{
Frame f = new Frame();
Label L = new Label("You have " + continues + " continues remaining.");
Button B = new Button ("Try Again?");
Label La = new Label("You're out of continues...");
Button But = new Button("Exit");
f.setLayout(new FlowLayout());
B.addActionListener(new ActionListener()
{
@Override
public void actionPerformed(ActionEvent e)
{
f.dispose();
}
});
if (continues <= 0)
{
f.add(La);
f.add(But);
/*
For clarification,
This actionListener is used
solely to do System.exit(0);
*/
But.addActionListener(li);
f.setSize(250,125);
}
else
{
f.add(L);
f.add(B);
f.setSize(250,100);
}
f.setLocationRelativeTo(null);
f.setAlwaysOnTop(true);
f.setVisible(true);
f.setTitle("You Hit A Mine!");
continues--;
}
This following chunk of code is used in order to build the board itself.
for (int i = 0; i < rows; i++)
{
int x = (int) ((Math.random() + .1) * 10);
minePlacement[i][0] = x;
mines[i][0] = new Button();
mines[i][0].addMouseListener(l);
mines[i][0].addActionListener(l);
add(mines[i][0]);
for (int j = 0; j < cols; j++)
{
int y = (int) ((Math.random() + .1) * 10);
minePlacement[i][j] = y;
mines[i][j] = new Button();
mines[0][j].addMouseListener(l);
mines[0][j].addActionListener(l);
mines[i][j].addMouseListener(l);
mines[i][j].addActionListener(l);
add(mines[i][j]);
}
I've tried looking for other posts which may answer my question, though as it stands, I have failed to find any other posts that have been coded in Java. I've mainly found them in C++ or C, to which I don't understand how the solution was brought about.
I'd like to know if there's any way to set a limit on the amount of windows on the screen, or if there's a way to prevent the window from popping up more times than expected.
Thanks in advance!
