yeah that line alone wont help much

#

seems like you iterate too high

#

something like

#

for(int i = 0; i<=10; i++){
}

instead of

for(int i = 0; i<10; i++){
}

#

yeah this is a mess

#

readability is 0

#

let me try and disentangle this

#

that is not the problem

#

fieldSize[mine[i][0]+1][mine[i][1]] != 9

#

this is

#

sorry

#

updated my message

#

well the problem is that mine[i][0]+1 can evaluate to 10

#

well

#

there you have it

#

if(mine[i][0]+1 <=fieldSize.length-1){ is true for 9

#

9+1 = 10

#

ah no

#

you added the one here also

#

you dont check for mine[i][1]

#

I guess

#

yeah but you have a call to fieldSize[mine[i][1]+1] before the check

#

in between the checks I should say

#

just make a sysout with mine[i][0]+1 and mine[i][1]+1 before you do all that so you can see for yourself in the console

Protip: clarifying printlns are always good for finding errors

#

What represents the value storaged in a position of the vector mine?

In the if statement is not being compared the index, but the value storaged in what the the index points summed with 1
