===============================================================
以上這邊是Server的程式部分,基本上與上課的大同小異,重點在於要在建立起一個新的Port 讓Client能夠同時連線...所以直接把中間那段,再見port的程式複製之後貼在下面,把port改3335,Server的部分就完成了...
===============================================================
至於Client的部分,也是利用上課的範例,把資料夾名稱改掉,再把專案載入進來,這樣就有兩個client的專案,一樣把第二個專案連結port的地方改掉,再把要輸出的字也改掉,就完成了..
