I'm trying to quickly access the bottom right corner of a 2 dimensional arr

Question

Hi. I'm trying to quickly access the bottom right corner of any 2 dimensional array. It's giving me some problems. It appears that "arrayName".length.length is incorrect. What is the correct way to do it? Help would be greatly appreciated. Thanks.
  if(gameGrid.length.length == 'X')
    cell = "alive";
    if(xCounter == 2 || xCounter == 3)
      // cell remains alive
    else
      cell = "dead";
      gameGrid.length.length = ' '; // this needs to be the bottom right [][]
  else
    if(xCounter == 3)
      gameGrid.length.length = 'X'; // this needs to be the bottom right [][]
      cell = "alive";
  xCounter = 0; // resets the counter

Answer 1

gameGrid.length is an int containing the length of an array
If you have an array
gameGrid[][] = new char[3][3]
then:
gameGrid is a 2-dimensional array
gameGrid.length = 3 (3 1-dimensional arrays)
gameGrid[0].length = 3 (gameGrid[0] is an array on itself)
gameGrid[1].length = 3 etc
In a 1-dimmensional array you get the last element with
myArray[ myArray.length - 1 ]
In a 2-dimmensional array its getting a bit trickier:
a = myArray.length - 1;
b = myArray[a].length;
bottomRight = myArray[a];
