I'm new to this site, however, I'm having problem hiding my broad when I start the game, I just want to make it invisible from the user. But I don't know where did I missed up with my code. Please help me out with this.
import java.util.Scanner;
public class MineSweeperGame {
int row, col;
boolean succes = false;
public static void main(String[] args) {
MineSweeperGame ms = new MineSweeperGame();
ms.run();
}
//
// Recursive reveal method
//
public void reveal(int x, int y, char[][] mineField, boolean[][] isVisible) {
int minx, miny, maxx, maxy;
int result = 0;
//
// if cell(x, y) is not mine, make sure visible that cell.
//
if (mineField[x][y] != '*') {
isVisible[x][y] = true;
//
// if cell(x, y) is blank, check all surrounding cells
//
if (mineField[x][y] == '.') {
//
// Don't try to check beyond the edges of the board...
//
minx = (x <= 0 ? 0 : x - 1);
miny = (y <= 0 ? 0 : y - 1);
maxx = (x >= row - 1 ? row - 1 : x + 1);

//
// Loop over all surrounding cells, call recursive reveal(i, j) method
//
for (int i = minx; i <= maxx; i++) {
for (int j = miny; j <= maxy; j++) {
if (isVisible[i][j] == false) {
reveal(i, j, mineField, isVisible);
}
}
}
}
} //
// if cell(x, y) is mine, do nothing.
//
else {
}
}
void printMineMap(char[][] mineField, boolean[][] isVisible) {
System.out.println();
succes = true;
//
// Loop over all cells, print cells
//
for (int x = 0; x < row; x++) {
for (int y = 0; y < col; y++) {
//
// Loop over all cells, print cells
//
if (isVisible[x][y]) {
System.out.print(" " + mineField[x][y] + " ");
} else {
System.out.print("[" + mineField[x][y] + "] ");
if (mineField[x][y] != '*') {
succes = false;
}
}
}
System.out.println();
}
if (succes) {
System.out.println("********** Congratulations~!!! You win. **********");
}
}
private void run() {
//
// Initialize MineField
//
char[][] mineField = MineField.getMineField();
row = mineField.length;
col = mineField[0].length;
boolean[][] isVisible = new boolean[row][col];

printMineMap(mineField, isVisible);

System.out.println("Canceled by user.");
break;
}
int y = in.nextInt() - 1;
if (x >= row || y >= col) // ignore invalid values
{
continue;
}
//
// Check cell(x,y) is mine, if yes, quit program

where and example of the game when it start ( I tried to post it as the game dose but every time I try it missed up the order).

Enter your guess (x y):
What I want is something like this
[] [] [] [] [] [] [] []
[] [] [] [] [] [] [] []
[] [] [] [] [] [] [] []
[] [] [] [] [] [] [] []

I feel like this is a weird way of doing this, but I'm assuming you're new to java and this is some sort of assignment or personal project to help yourself learn.
From what I can tell, It looks like your if statement is doing the same thing for both if and else. Consider changing the else statement to print "[ ]"
if (isVisible[x][y]) {
System.out.print(" " + mineField[x][y] + " ");
} else {
System.out.print("[" + mineField[x][y] + "] ");
if (mineField[x][y] != '*') {
succes = false;
}
}
In other words, the above should be:
if (isVisible[x][y]) {
System.out.print(" " + mineField[x][y] + " ");
} else {
System.out.print("[ ] ");
if (mineField[x][y] != '*') {
succes = false;
}
}
Maybe give that a shot?
