現(xiàn)在銀行遍地開(kāi)花，在城市了差不多每隔200米就可以看到一家銀行。在銀行叫號(hào)排隊(duì)也就成了很平常的事情。但是很讓人生氣的是在咱們這個(gè)世界上最大的社會(huì)主義國(guó)家里，在銀行排隊(duì)卻很不公平，咱們這些沒(méi)錢(qián)的人（在銀行里存錢(qián)不多，持普通卡）每次排隊(duì)都要等很長(zhǎng)一段時(shí)間才能辦理業(yè)務(wù)，而且沒(méi)有工作人員來(lái)招呼，而那些有錢(qián)人（在銀行里存了很多錢(qián)，持“金卡”）卻不用等，隨時(shí)可以辦理業(yè)務(wù)，還美其名曰“金卡”特權(quán)。難道有錢(qián)就有特權(quán)嗎？氣憤中……...

還是說(shuō)這個(gè)系統(tǒng)吧：

銀行大廳里有一個(gè)叫號(hào)機(jī)（顧客客戶端），如果持普通卡點(diǎn)一下辦理業(yè)務(wù)按鈕就會(huì)打印一張小條，顯示你的號(hào)碼和排在你前面的人數(shù)；如果持金卡，點(diǎn)一下辦理業(yè)務(wù)就會(huì)提示下一位要辦理的客戶就是你。

每個(gè)業(yè)務(wù)辦理窗口都有一個(gè)工作人員客戶端，點(diǎn)擊下一位就會(huì)從等待的客戶隊(duì)列中取出第一位到該窗口辦理。

客戶，也就是等待的人，要有號(hào)碼、排在前面的人數(shù)等屬性，然后實(shí)現(xiàn)這些屬性的set、get方法。

Waiter

Waiter
package queuebanknew;

public class Waiter {
	private int num;
	private int frontNum;
	private int flag;
	public int getFlag() {
		return flag;
	}
	public void setFlag(int flag) {
		this.flag = flag;
	}
	public int getNum() {
		return num;
	}
	public void setNum(int num) {
		this.num = num;
	}
	public int getFrontNum() {
		return frontNum;
	}
	public void setFrontNum(int frontNum) {
		this.frontNum = frontNum;
	}
	

}

工作人員，也就是窗口的處理業(yè)務(wù)的人員，她們有自己的編號(hào)，姓名，顧客，實(shí)現(xiàn)這些屬性的set、get方法，還加入了一段工作過(guò)程的代碼。

Counter

Counter
package queuebanknew;

public class Counter {
	private int id;
	private String name;
	private Waiter w;
	public Counter(Waiter waiter) {
		this.w=waiter;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Waiter getW() {
		return w;
	}
	public void setW(Waiter w) {
		this.w = w;
	}
	public void handBussines(){
		System.out.println("正在處理："+this.w.getNum()+"號(hào)");
		try {
			Thread.sleep(1000);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
		System.out.println("處理完畢："+this.getW().getNum());
	}

}

測(cè)試一下：

TestBankQueue
package queuebanknew;

import java.util.Queue;

public class TestBankQueue {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		
		QueueServer qs = new QueueServer();
		Queue<Waiter> waiterList = qs.init();//初始化10個(gè)等待者
		Waiter waiter= null;
		while(true){//模擬工作人員處理業(yè)務(wù)
			waiter = waiterList.poll();
			if(waiter != null){
				Counter counter = new Counter(waiter);
				counter.handBussines();
			}else{
				break;
			}
		}
	}
}

結(jié)果：

服務(wù)器端：

QueueServer
package queuebanknew;

import java.util.LinkedList;


public class QueueServer {
	LinkedList<Waiter> waiterList = new LinkedList<Waiter>();
	
	public LinkedList<Waiter> init(){
		for(int i=1;i<=10;i++){
			Waiter w = new Waiter();
		    w.setNum(i);
		    w.setFrontNum(i-1);
		    waiterList.offer(w);
		}
		return waiterList;
		
	}

}

BankWorkerUI

工作人員客戶端：

BankWorkerUI
package queuebanknew;

import org.eclipse.swt.events.SelectionEvent;

public class BankWorkerUI {
	public static void main(String[] args) {
		final Display display = Display.getDefault();
		final Shell shell = new Shell();
		shell.setSize(327, 253);
		shell.setText("銀行排隊(duì)---工作人員客戶端");
//		新插入的界面核心代碼
		QueueServer qs = new QueueServer();
		final Queue<Waiter> waiterList = qs.init();
		
		final Text txt = new Text(shell,SWT.MULTI);
		txt.setBounds(65,30,180,70);
//		事件代碼里要訪問(wèn)button
		final Button button = new Button(shell,SWT.Activate);
		button.addSelectionListener(new SelectionAdapter(){
			public void widgetSelected(SelectionEvent e){
				Waiter waiter = waiterList.poll();
				if(waiter!=null){
					txt.setText(waiter.getNum()+"號(hào)顧客到1號(hào)窗口辦理");
				}else{
					txt.setText("沒(méi)人辦理業(yè)務(wù)");
				}
			}
		});
		button.setBounds(90, 141, 100, 25);
		button.setText("下一個(gè)");
