Help!! Placing obstacles on a maze.

Hi, so I have a 2D int array providing me some positions let's say {3,4}{0,1} and I have a 2D char array which is full of dots '.' All I wanna do is place an obstacle '#' in the char array at positions given in the int array. It should be really easy but couldn't figure out please help me.

Show us what you tried... If not started, then take a loop, with if, where row, colomn is set in int array, assign # in char array on same row, colomn index...

char[][] maze = new char[5][5]; int [][] obstacles = {{1,1},{2,2},{3,3}}; for (int[] p: obstacles) { maze [p[0]] [p[1]] = '#'; }
