//JimWin類
//JIM主界面類。該類通過列表顯示出好友及好友的狀態，并通過快捷菜單的方式提供收發信息、查看好友資料、增加好友和刪除好友的功能。代碼如下：
class JimWin extends JFrame implements Runnable
{ int myImNo; //本人的JIM號
Vector myFriends=new Vector();//好友的列表
String[] faceOnline; //在線時好友圖像文件名
String[] faceOffline; //離線時好友圖像文件名
Thread thread; //接收信息線程
//以下是網絡相關變量
String serverName; //服務器名或IP地址
int serverPort; //服務器端口號
byte receiveBuf[ ]=new byte[512]; //UDP方式接收數據的數據緩沖區
DatagramPacket receivePacket; //接收數據報Packet
DatagramSocket receiveSocket; //接收數據報Socket
//默認接收消息的UDP端口號。
//若在同一臺計算機上啟動多個JIM端口號將自動加1
int udpPORT=5001;
//以下是程序界面的變量
JPanel contentPane;
JScrollPane jspList; //滾動面板
JList jlstFriend; //好友列表，將放置在滾動面板上
JPopupMenu jPopupMenu1=new JPopupMenu(); //快捷菜單
JMenuItem mnItemMsg=new JMenuItem(); //收發訊息菜單
