Final condition failed. Code works as requested

Question about the task

Under discussion

Like others, I am having trouble with the final condition. I used a different method for the recursion, making a List that adds the coordinates of all neighbours that also need to be run through openTile(x,y). Line 38 clearly makes those cells show nothing with "". I have also tried commenting out that line so they have no value and it still errors. Please try this code, it works perfectly but fails the final condition

According to the rules, when a cell without adjacent mines is revealed, the game reveals the "unmined" area up to cells with mined neighbors. Let's implement it... I suggest using recursion. It is used when the algorithm for solving the problem is the same as the algorithm for solving part of the problem. Here's what we have.

When a cell with zero mined neighbors is revealed, we need to do a full search of all neighboring cells that haven't been revealed, call openTile(int, int) method on them, and repeat the process.

Additionally, in the openTile(int, int) method, we'll arrange to display the number of mined neighbors of a cell.

Run the game to verify that the implementation is correct.

Hint: if you get a java.lang.StackOverflowError, it means that you're setting the isOpen flag too late.

Requirements:

In the openTile(int, int) method, if the element is not a mine and has no mined neighbors, the openTile(int, int) method must be called recursively on each neighbor that hasn't been revealed.
The openTile(int, int) method must call the getNeighbors(GameObject) method if the element is not a mine and has no mined neighbors.
In the openTile(int, int) method, if the element is not a mine and has at least one mined neighbor, the number of mined neighbors must be displayed on the playing field. Use the setCellNumber(int, int, int) method.
The openTile(int, int) method must not display anything if the element is not a mine and has no mined neighbors. Use an empty string.

package com.codegym.games.minesweeper; public class GameObject{ public int x; public int y; public boolean isMine; public int countMineNeighbors; public boolean isOpen; public boolean isFlag; public GameObject(int x, int y, boolean isMine){ this.x=x; this.y=y; this.isMine=isMine; } }

It looks like there are changes to the required code. One such is that the getNeighbors() method should be returning an int, not a list. Changing or removing code not specified by the conditions is almost always an automatic fail, as validation system test for those things specifically.

that is strange because this is the getNeighors() code that the tutorial gave me. I have not changed it. But I did see in the other Help questions that everyones looked different.

I don't like giving help on these big tasks because there are so many different variables and I have no idea, or way to tell, what part of the code the validation system is sputtering at. I tried your code, by copying and pasting the openTile() into my solution (and modifying the getNeighbors() part to work with mine). It works as far as I can tell.
