【说明】 IC卡和200卡都是从电话卡派生的。下面的程序将电话卡定义为抽象类。其中 balance为双精度变量，代表电话卡中的余额；cardNumber是长整型变量，代表电话卡的卡号；password是整型变量，代表电话卡的密码；connectNumber是字符串变量，代表电话卡的接入号码；connected是布尔变量，代表电话是否接通。 performDial()实现各种电话接通后的扣除费用的操作。其中200卡每次通话扣除0.5元的通话费用和附加费用；IC卡每次通话扣除0.9元的通话费。TimeLeft()方法用于测试电话卡余额还可以拨打电话的次数。performConnection()用于电话接入操作，如果卡号和密码正确，则接通；否则，接不通。【程序】 abstract class PhoneCard doubte balace; (1) perfermDial(); double getBalance() return balance; double TimeLeft() double current=balance; int times=0; do (2) times++; white(balance＞=0); balance=current; return times-1; abstract class Number_PhoneCard extends PhoneCard long cardNumber: int password; String connectNumber; Boolean connected; Boolean performConnection(long cn, int pw) if(cn==cardNumber && (3) ) connected=true; return true; else return false; class IC Card (4) boolean performDial() if(balance＞0.9) balance-=0.9; return true; else return false; class D200_Card (4) static double additoryFee; static additoryFee=0.1; boolean performDial() if(balance＞(0,5+additeryFee)) (5) return true; else return false;
