Im unsure of how i can put either the x or an o into my 2d array for my 7x7 naughts and crosses type game?

class cell{
  String player;
  int turnNum;
  char shape;
  cell(int row, int col){
 
  }
}

cell[][] grid=new cell[7][7];

Here, I’ve hashed out your example a bit more.

String player;
int turnNum;

class Cell {
  int symbol;
  Cell() {
    symbol = 0;
  }
  void assign(int new_symbol) {
    symbol = new_symbol;
  }
  void draw() {
    noFill();
    stroke(255);
    rect(-25,-25,50,50);
    //rect(0,0,20,20);
    if ( symbol == -1 ) {
      fill(0, 0, 200);
      text("X", 0, 0);
    } else if ( symbol == 1 ) {
      fill(200, 0, 0);
      text("O", 0, 0);
    }
    //fill(255);
    //text("(" + symbol + ")", 15,0);
  }
}

Cell[][] cells = new Cell[7][7];

void setup() {
  size(350, 350);
  player = "AwesomePlayerName";
  turnNum = -1;
  for ( int i = 0; i < 7; i++) {
    for ( int j = 0; j < 7; j++) {
      cells[i][j] = new Cell();
      cells[i][j].assign(int(random(-2, 2)));
    }
  }
}

void draw() {
  background(0);
  for ( int i = 0; i < 7; i++) {
    for ( int j = 0; j < 7; j++) {
      pushMatrix();
      translate(25+50*i, 25+50*j);
      cells[i][j].draw();
      popMatrix();
    }
  }
}

Notice that each Cell (now with a Capital C, as this is the naming convention for class names), needs only to store a single int to track if it is an X or an O. The symbol drawn in a Cell is based on the value stored in that Cell’s symbol variable.
