我們今天來(lái)做一個(gè)醫(yī)院掛號(hào)排隊(duì)系統(tǒng)：分為病人，醫(yī)生，服務(wù)器三個(gè)類。
病人：我只關(guān)心我掛哪個(gè)專家的號(hào)，我排在掛這個(gè)專家的隊(duì)列里的位置和前面的人數(shù)。
醫(yī)生：我有我的屬性（id，name，需要看病的病人），而且我有一個(gè)處理病情的方法；我只關(guān)心掛我的號(hào)的人有多少，每次我只需要去從隊(duì)列里取出病人就可以了，這就夠了。
服務(wù)器：服務(wù)器需要設(shè)置一個(gè)Map（鍵值對(duì)應(yīng)關(guān)系），將每一個(gè)醫(yī)生對(duì)應(yīng)的id和他的病人隊(duì)列一一對(duì)應(yīng)起來(lái)，需要初始化一些病人存儲(chǔ)在每個(gè)醫(yī)生的病人隊(duì)列里。
再說(shuō)UI：
病人客戶端UI：
在點(diǎn)擊事件監(jiān)聽器里：我需要知道排在我前面的人數(shù)有多少，我的位置是多少，需要將服務(wù)器的隊(duì)列取過(guò)來(lái)處理。
醫(yī)生客戶端UI：
再點(diǎn)擊事件監(jiān)聽器里：我只需要一個(gè)一個(gè)的叫下一位病人的名字或者號(hào)碼就可以了。
