Comparing chars at positions in an array

[Shaggy Rogers]

Hello all, I'm coding something like

for(int i = 0; i < maze.length; i++)
{
for(int x = 0; x < maze[0].length; x++)
{
if(maze[i][x] == ('.'))
{
maze[i][x] == ('!');
}
System.out.print(maze[i][x]);
}

that finds a '.' char in a 2D array and replaces it with a '!' character. However, using == does not work. I have tried using .equals as well and get a dereferencing error. Any help on how to compare the characters would be greatly appreciated, thanks.

This is nothing wrong with the comparison. It is the assignment that is incorrect. Don't you mean this...

  maze[i][x] = ('!');

The "==" is not a valid assignment operator.

Did you mean for the second == to be =?
