我在这里的问题是，当我设置我的
时

my problem in here is that when i set my

private Barber barbers[]=new Barber[3]; 

进入

into

private Barber barbers[]=new Barber[1];

取消对我的理发师[1]和理发师[2]的注释，以便我只想出现在理发店中的就是理发师[0] ...但是我有一个问题，当我在第一个客户中添加客户时，就没有了问题，但是当我添加客户3次时，他们应该首先等待一个理发师，因为没有理发师会剪头发，因为我只设置了理发师[1]，那么即使它没有理发师也会剪头发，我的客户即使没有理发师也总是坐...请帮助我...

And uncomment my barbers [1] and barbers [2] so that what i want only to appear in barber shop is the barbers [0]... But i have a problem, when i adding customer at the first one, dont have a problem but when i add customers 3 times, they should wait first the one barber because there are no barbers that will cutting hair, because i only set my Barber [1], then even it dont have barbers that will cut the hair, my customers always sit even it dont have barbers... please help me...

barbers[0].setBounds(92,112,30,130);
// barbers[1].setBounds(71,235,30,130);
// barbers[2].setBounds(49,354,30,130);

推荐答案

1.我们不代表您从互联网上下载代码.
2.我们没有时间编译，运行和调试您的程序.

用技术术语解释问题并显示失败的代码，然后人们会设法帮助您.

1. We do not download code from the internet on your behalf.
2. We do not have time to compile, run and debug your program.

Explain your problem in technical terms and show the failing code and people will try to help you.

因此，您必须使程序等待Barber-Object barbers[0]可用.
实际上，您必须使程序等待barbers的任何数字x并始终询问if(false == barbers[i].isBusy()).

一些线程处理 [

So you have to make the program wait for the Barber-Object barbers[0] to be usable.
In fact you have to make the program wait for any number x of barbers and always ask if(false == barbers[i].isBusy()).

Some Thread Handling[^] should also be suitable. It makes waiting easier.
