java - Game with server and multiple client, make sure only one game object is created -

i'm trying write poker server , client program, create game in server class , client class takes output , displays them. however, when ever this, there seem 2 game objects created, first player gets input consistent object shown in console, second player displays cards not shown in sysout method, , can not seem find created second game object.

server class:
