I'm writing minesweeper for class and we don't have to have a working GUI but we still need to have some type of grid that will show up on command prompt when the game is run. I am thinking about building a grid that will look something like this +-----+-----+
| X | X | for two cells. How should i design it so that i can connect the grid to my 2D arrays that represent what is inside the cell.
So, you already have the content of the grid in a 2D array? You could write a method that prints the grid on the console. You'll probably want to have nested for-loops: one loop over the rows, which contains another loop over the columns.
To enlarge on what Jesper said (you didn’t really say 2D array, did you, Jesper?), you can iterate along the line setting X characters, or maybe others like █ = (char)0x2588 and (char)0x2716 = ✖. I would have thought that is easiest done with a char; you can set individual characters in such an array very quickly.
