im trying to do minesweeper in java. I’m using matrix. I want to know which row and columns has mine which is “* “.
Which method can i use.

i create mine matrix like that and i want to determine every mine position like 4,3 5,2 7,1. How can i do it. I tried .equals but it didnt gone quiet well.

for (int i = 0; i < 10; i++) {
                int xAxis = randomMines.nextInt(1, 10);
                int yAxis = randomMines.nextInt(1, 10);
                if (hiddenMatris[xAxis][yAxis] == "* ") {
                    i--;
                }
                hiddenMatris[xAxis][yAxis] = "* ";
