Replacing Character at Specific Location in 2D Array?

Question

I have two integers representing a specific location in a 2D array of characters, and I'm trying to write a method that will take those integers, use them as index locations in the array, and replace them with a new character, '.' (the method will then return the array to the main method).

Here's the (currently empty) method:

public static char[][] playerMoveDown(int playerPosR, int playerPosC, char[][] mazeGrid) {



}

I'm trying to do something to the effect of this:

mazeGrid[][].setCharAt(mazeGrid[playerPosR][playerPosC], '.');

But with something that works for a character array (since setCharAt only works for strings). What's a simple and easy way to this?

Answer 1

怎么样

mazeGrid[playerPosR][playerPosC] = '.';

Answer 2

What about this:

public static char[][] playerMoveDown(int playerPosR, int playerPosC, char[][] mazeGrid) {
    mazeGrid[playerPosR][playerPosC] = '.';
    return mazeGrid;
}

I suggest getting familiar with array syntax before proceeding further...
