1、實現租車汽車租賃系統，不同車型日租金情況如表 7-1所示;車型及日期轎車客車車型別克Gl8寶馬750別克凱越二19 座>19座日租金（元 /天）7506005008001200編程實現計算不同車型不同天數的租賃費用。package zuche;public abstract class MotoVehicle privateStringno;privateStringbrand ;int 口 fee = 750,600,500,800,1200; public MotoVehicle() public MotoVehicle(String no,String brand ) this .

2、 no=no; this . brand =brand ;public String getNo() return no;public String getBrand() return brand ;public void setBrand(String brand ) this . brand =brand ;public void setNo(String no) this . no=no;public void printInfo() System. out .println( "* 汽車的信息*" +"n 汽車品牌"+this . brand +

3、"n 車牌號"+this . no); public abstract void calRent( int days);package zuche;public class Car extends MotoVehicle private String type ;/String type1= "別克凱越","寶馬730","別克凱越","中小客車(19座以 內)","大型客車(19座以上)"public Car() public Car(String no,String br

4、and ,String type ) super (no, brand );this . type =type ; )public String getType() return type ;)public void setType(String type ) this . type =type ;)public void printInfo() /super.printInfo();調用父類的構造方法，子類不能直接繼承父類的構造方法；System. out .println( "* 汽車的信息*" +"n 汽車品牌"+getBrand()+ "

5、;n 型 號"+this . type +"n 車牌號"+getNo();)public void calRent( int days ) int rent =0;if ("寶馬".equals(getBrand() rent =days *600; else if ("另1J克".equals(getBrand()&&'gl8" .equals( this . type ) rent =days *750; elserent =days *500;System. out .println(

6、 "你的租車費用為"+rent +"元")；package zuche;public class Bus extendsMotoVehicle private int seatCount ; public Bus() public int getSeatCount() return seatCount ;public void setSeatCount( int seatCount ) this . seatCount =seatCount ; public void printInfo() System. out .println(''

7、* 汽車的信息*刈 +"n 車牌號"+getNo()+ "n 客車座位藪"+this . seatCount +"座")；)public void calRent( int days) int rent =0;if ( seatCount <=19) rent =days *800; else rent =days *1200;System. out .println( "你的租車費用為"+rent +"元")； package zuche;import java.util.Scanner

8、;public class TestRent public static void main(String args ) Scanner input =new Scanner(System. in ); /int carType;String answer;int day =0;Car c=new Car();"*歡迎光臨西樹東花租車*");,、*,、 、Bus b=new Bus();System. out .println(System. out .println(int random =(int )(Math. random ()*89999+10000); /ran

9、dom()的取值范圍為0,1);do System. out .println("轎車請選:1" +"n 貨車請選:2");c.setNo("黑At" +random);if (input .nextInt()=1) System. out .println("請輸入汽車的品牌(1.寶馬、2.別克)")；switch (input .nextInt() case 1:c.setBrand("寶馬");c.setType( "730");c. printInfo();Syste

10、m. out .println("請輸入租車天數");c.calRent( input .nextInt(); break ;case 2:System. out .println("請選擇別克車的類型：if (input .nextInt()=1) c.setBrand("別式");c.setType( "gl8");c. printInfo();System. out .println( "請輸入租車天數");c .calRent( input .nextInt(); else c.setBrand(

11、"別克");c.setType("凱越");c. printInfo();System. out .println( "請輸入租車天數");c .calRent( input .nextInt();else System. out .println( "請選擇客車的座位數: b.setNo("黑A" +random);switch ( input .nextInt() case 1: b.setSeatCount(17);b.printInfo();System. out .println( "請輸入租車天數");b.calRent( input .nextInt(); break ; case 2:b.setSeatCount(21);b.printInfo();System. out .println("請輸入租車天數");b.calRent( input .nextInt(); break ;System. out .println("是
