How to open cells where there are no bombs for the Minesweeper game?

Question

Java

I'm writing a sapper game in JavaFX, I can't figure it out.
There is a field of squares. Any square can be accessed through the grid along the x and y axes:
grid.get(0, 3);
grid.get(0, Y_TILES);
Each square has an int variable, this is the number of bombs around;
grid.get(0,0).bombsAround.
When clicking on a square that has bombsAround==0, I want all neighboring squares that also have 0 to open. The game is already working, but you just have to poke many times where there are no bombs.

Answer 1

recursion to help you.
for each adjacent cell without bombs nearby, open all neighboring cells without bombs nearby.
there may be an overhead from the fact that some cells will be "opened" several times, so I would introduce a boolean flag isOpened
