Unexpected Token [ when using Arrays

Hi all-
I'm writing a program that puts new instances of a class into an array. As far as I can tell, my syntax are correct, but I'm getting an unexpected token error on line 2. The main body of the program is copied below, with the class definition below it.
Thank you in advance for any help!

Main Program:
Grid[] grids = new Grid[2];

void setup () {
size (500, 500);
background (255);
grid [1];
grid [0];
}
void draw () {
gridtwo.drawGridbottomright ();
gridone.drawGridbottomleft ();
gridone.drawGridtopright ();
gridtwo.drawGridtopleft ();
}
Class
