JAVA题目，求代码。

只发主函数代码 public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("输入本金数目："); double count = sc.nextDouble(); System.out.println("一年到期本息总和为：" + count * 1.0225); System.out.println("两年到期本息总和为：" + count * Math.pow(1.027, 2)); System.out.println("三年到期本息总和为：" + cou

java的问题，求代码

String本身就有。 ~ ~~~~~~ ~~~~~~~~~~ ~~~~

java难题，急，求代码？

接口和类全在一个包下，如果不在一个包下记得import调用，show的重写你根据需要自己改

//ShouFei接口
publicinterfaceShouFei{
publicvoidfuFei(doublemileage);
publicvoidshow();
}
//Bus类
publicclassBusimplementsShouFei{
StringairConditioning;
doublemoney;
publicBus(StringairConditioning){
this.airConditioning=airConditioning;
}
@Override
publicvoidfuFei(doublemileage){
if(airConditioning.equals("空调")){
money=2;
}else{
money=1;
}
}
@Override
publicvoidshow(){
System.out.println("公交车，"+airConditioning+",费用："+money);
}
}
//Taxi类
publicclassTaxiimplementsShouFei{
doublemileage;
booleanisDay;
doublemoney;
publicTaxi(booleanisDay){
this.isDay=isDay;
}
@Override
publicvoidfuFei(doublemileage){
this.mileage=mileage;
//判断是否为白天
if(isDay){
//判断里程数是否大于三公里
if(mileage<3){
money=8;
}else{
money=8+(mileage-3)*1.5;
}
}else{
if(mileage<3){
money=10;
}else{
money=10+(mileage-3)*1.5;
}
}
}
@Override
publicvoidshow(){
System.out.print("出租车,");
if(isDay){
System.out.print("白天");
}else{
System.out.print("晚上");
}
System.out.println(",里程数："+mileage+"收费:"+money);
}
}
//测试类
publicclassTest{
publicstaticvoidmain(String[]args){
Busbus=newBus("空调");
bus.fuFei(10);
bus.show();
Taxitaxi=newTaxi(true);
taxi.fuFei(20);
taxi.show();
}
}
