Minesweeper game help

I am making minesweeper, and so far I have made an array of the 'button' class (which is the part that covers the 'background' class, as in minesweeper), and I made a constructor in the button class, to identify whether there is a mine under it (true), or not (false).
?

This is the world class, and the problem is that when the world generates, the button class generates only with isKill being true. None of them are false. I need all ones not over mines to be false. Don't know why that code isn't running. Thanks.

I don't think that you should do the mine placement from the act method. You should do the creation of the mines and non-mines fields from the constructor. Why do you have this background class? I would do this: - add the 256 buttons - randomly choose 40 and set a variable in them to true (mine below) - when a button is clicked, show a mine or a number based on the variable and the variable from the neighbors
