$8*\{$@code ConnectFour$\}$ represents a two$-$player connection game involving a two$-$dimensional grid$\backslash$

of

$9*\{$@linkplain cs$1302.$gameutil.Token tokens$\}.$ When a $\{$@code ConnectFour$\}$ game object is

$10*$ constructed, several instance variables representing the game's state are initialized and

$11*$ subsequently accessible, either directly or indirectly, via "getter" methods. Over time, the

$12*$ values assigned to these instance variables should change so that they always reflect the

$13*$ latest information about the state of the game. Most of these changes are described in the

$14*$ project's

$15*$ functional requirements.
