java模拟收费代码 java收费了

IT技术String

利用java编写一个电话扣费的程序public class Test extends PhoneKouFei{
public Test(String startTime, String stopTime) {
super(startTime, stopTime);
}
public static void main(String[] args) {
String start = "00:12:23";
String stop = "00:15:23";
new Test(start,stop);
}
}
abstract class PhoneKouFei{
private final double fei = 1.5;//1分钟扣1毛5
public String startTime; //通话开始时间
public String stopTime; //通话结束时间
public PhoneKouFei(String startTime, String stopTime){
this.startTime = startTime;
this.stopTime = stopTime;
System.out.println("通话时常java模拟收费代码：" +getKouFei()+ "分钟");
System.out.println("应扣费java模拟收费代码：" + (double)getKouFei() * fei);
}
//扣费方法
private final long getKouFei(){
java.text.SimpleDateFormat sim = new java.text.SimpleDateFormat("HH:mm:ss");
try {
java.util.Date start = sim.parse(this.startTime);
java.util.Date stop = sim.parse(this.stopTime);
return (stop.getTime() - start.getTime()) / 60000;
} catch (java.text.ParseException e) {
throw new RuntimeException("时间格式错误..");
}
}
}
//输出结果：
通话时常：3分钟
应扣费：4.5
java 编程，停车收费简易系统代码如下,仅实现功能,未考虑安全等情况.
//ParkingTest.java
/**
* 停车程序入口.本示例为考虑数据安全等.仅作为示例,未经调试.

public class ParkingTest {
public static void main(String[] args) {
// 程序入口,可以安排停车出车
for (int i = 0; i100; i++) {
if (ParkingManage.hasPosition()) {
ParkingManage.enterParking(i + "");
continue;
}
break;
}
for (int i = 0; i100; i++) {
ParkingManage.outParking(i + "");
}
System.out.println(ParkingManage.totalCost());
}
}
