Jlabel not updating
But it took a while for the most important rule in the game to dawn on me: You don’t get to pick which of the nine boards to play on. When all is said and done, X has sacrificed the center board in exchange for superior position on the other eight. It stings to lose that center board without a fight.
That’s determined by your opponent’s previous move. You’ve got to consider where your move will send your opponent, and where his next move will send you, and so on. Players seem to move randomly, missing easy two- and three-in-a-rows. O grabs a three-in-a-row, laughing at your stupidity. But forcing so many O’s to cluster uselessly together on one board gives X the upper hand for the rest of the game.
In reality using the Mediator pattern for a chat room would only be practical when used with remoting.
design pattern is one of the twenty-three well-known Go F design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.
Defining a set of interacting objects by accessing and updating each other directly is inflexible because it tightly couples the objects to each other and makes it impossible to change the interaction independently from (without having to change) the objects.
And it stops the objects from being reusable and makes them hard to test.
Tightly coupled objects are hard to implement, change, test, and reuse because they refer to and know about many different objects.
