Question
JAVA: I would like to integrate my working Grid Class (GUI) into a client/server two player program, similiar to the attached tic tac toe program.
JAVA: I would like to integrate my working Grid Class (GUI) into a client/server two player program, similiar to the attached tic tac toe program. Just so that both players can click the column buttons and populate the game. I am having issues impementing some of the code. Thanks! ***********Grid/GUI***********
