1.当我们去银行办理什么业务的时候总会先在一个类似电脑的小系统上去一个号，然后等着，当被叫到时就去相应的窗口办理业务，这种排队的小系统主要用到了接口Queue，因为它符合队列的要求先进先出。
2.还有就是有种特殊情况就是，银行的金卡用户，他们的权限较高，总可以在普通用户的前面办理业务
相应代码如下：
package com.dr.queue;
public class Counter 
{
private int counterId; //���й�̨���ں�
private String counterName; //���й�����Ա������
private Waiter w;
public Counter(Waiter w){
this.w = w;
}
public Waiter getW() {
return w;
}
public void setW(Waiter w) {
this.w = w;
}
public int getCounterId() {
return counterId;
}
public void setCounterId(int counterId) {
this.counterId = counterId;
}
public String getCounterName() {
return counterName;
}
public void setCounterName(String counterName) {
this.counterName = counterName;
}
public void handleBusiness(){
System.out.println("I handling the " + this.w.getNum() +" waiter");
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("I have handled the waiter,next ,next ,next");
}
}
package com.dr.queue;
public class Waiter {
private int num;
private int frontNum;
private int flag;//0=普通 1= 金卡
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;
}
}

w.setFrontNum(i-1);
waiterList.offer(w);

return waiterList;
