用JAVA编写一个出售通行证的方法和另一个出售门票的方法
您好,我正在尝试编写满足以下输出的代码:用JAVA编写一个出售通行证的方法和另一个出售门票的方法,java,object,methods,constructor,drjava,Java,Object,Methods,Constructor,Drjava,您好,我正在尝试编写满足以下输出的代码: Here are the booths at the start: Ticket booth with 5 passes and 50 tickets Ticket booth with 1 passes and 10 tickets Booth 1 has made $43.0 Booth 2 has made $20.5 Here are the booths at the end: Ticket booth with 3 pass
Here are the booths at the start:
Ticket booth with 5 passes and 50 tickets
Ticket booth with 1 passes and 10 tickets
Booth 1 has made $43.0
Booth 2 has made $20.5
Here are the booths at the end:
Ticket booth with 3 passes and 30 tickets
Ticket booth with 0 passes and 2 tickets
我可以在前三行中使用它,但是我在编写sellPass()、sellTickets()和MoneyMake()的方法时遇到了问题。以下是用于输出我的代码的测试仪代码:
public class TicketBoothTestProgram
{
public static void main(String args[])
{
TicketBooth booth1, booth2;
booth1 = new TicketBooth(5, 50);
booth2 = new TicketBooth(1, 10);
System.out.println("Here are the booths at the start:");
System.out.println(" " + booth1);
System.out.println(" " + booth2);
// Simulate selling 2 passes, 5 tickets, 12 tickets and 3 tickets from booth1
booth1.sellPass();
booth1.sellPass();
booth1.sellTickets(5);
booth1.sellTickets(12);
booth1.sellTickets(3);
// Simulate selling 2 passes, 5 tickets, 12 tickets and 3 tickets from booth2
booth2.sellPass();
booth2.sellPass();
booth2.sellTickets(5);
booth2.sellTickets(12);
booth2.sellTickets(3);
// Make sure that it all worked
System.out.println("\nBooth 1 has made $" + booth1.moneyMade);
System.out.println("Booth 2 has made $" + booth2.moneyMade);
System.out.println("\nHere are the booths at the end:");
System.out.println(" " + booth1);
System.out.println(" " + booth2);
}
}
下面是我试图编写方法的代码:
public class TicketBooth
{
float moneyMade;
int availablePasses;
int availableTickets;
static float TICKET_PRICE = 0.50f;
static float PASS_PRICE = 16.50f;
public TicketBooth()
{
moneyMade = 0.0f;
availablePasses = 0;
availableTickets = 0;
}
public TicketBooth(int p)
{
moneyMade = 0.0f;
availablePasses = p;
availableTickets = 0;
}
public TicketBooth(int p, int t)
{
moneyMade = 0.0f;
availablePasses = p;
availableTickets = t;
}
public String toString()
{
return("Ticket booth with " + this.availablePasses + " passes and " + this.availableTickets +
" tickets");
}
public sellPass()
{
//INSERT CODE HERE FOR SELLING A PASS
}
public sellTickets()
{
//INSERT CODE HERE FOR SELLING A TICKET
}
}
感谢您的帮助,谢谢 您的sellPass()
方法相当简单。我添加了boolean
返回类型,如果车票或通行证用完,将返回false
public boolean sellPass() {
//Check if you have a pass to sell
if (availablePasses > 0) {
//you have passes to sell
moneyMade += moneyPerPass; // add the money
availablePass--; //decrement pass counter
return true;
}
return false; // not enough passes to sell
}
与您的sellTickets(int noOfTickets)
相同,您的方法应该允许您销售多少张票
public boolean sellTickets(int noOfTickets) {
if(availableTickets >= noOfTickets) {
moneyMade += noOfTickets * pricePerTicket;
availableTickets -= noOfTickets;
return true;
}
return false;
}
具体来说,您遇到了什么问题?我想您的
sellPass/Tickets
方法将需要一个数量。您需要检查手头是否有所需的数量,如果没有,可能会引起某种错误。按数量减少“手头数字”值,并将价格x数量
添加到挣钱中…你怎么知道一张票多少钱和一张通行证多少钱?@Rp-我声明,一张票的价格是0.50美元,一张通行证是16美元。50@MadProgrammer它以5张通行证和50张票开始(对于booth1),对于booth2,它以1张通行证和10张票开始。在booth1中,它以3个通行证和30张票结束,而对于booth to,它以0个通行证和2张票结束。我假设编译时错误是故意存在的,因此OP需要自己解决一些问题。;)
