<P> IC卡和200卡都是從電話卡派生。下面程序?qū)㈦娫捒ǘx為抽象類。其中balance為雙精度變量，代表電話卡中的余額;cardNumber是長(zhǎng)整型，代表電話卡的卡號(hào);password是整型變量，代表電話卡的密碼;connectNumber是字符串變量，代表電話卡的接入號(hào)碼;connected是布爾變量，代表電話是否接通。</P>
<P> performDial()實(shí)現(xiàn)各種電話接通后的扣除費(fèi)用的操作。其中200卡每次通話扣除0.5元的通話費(fèi)用和附加費(fèi)用;IC卡每次通話扣除0.9元的通話費(fèi)。TimeLeft()方法用于測(cè)試電話卡余額還可以撥打電話的次數(shù)。performConnection()用于電話接入操作，如果卡號(hào)和密碼正確，則接通，否則，接不通。</P>
