1.當我們去銀行辦理什么業務的時候總會先在一個類似電腦的小系統上去一個號，然后等著，當被叫到時就去相應的窗口辦理業務，這種排隊的小系統主要用到了接口Queue，因為它符合隊列的要求先進先出。
2.還有就是有種特殊情況就是，銀行的金卡用戶，他們的權限較高，總可以在普通用戶的前面辦理業務
相應代碼如下：
package com.dr.queue;
public class Counter 
{
private int counterId; //???й???????
private String counterName; //???й????????????
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;
}
}
package com.dr.queue;
import java.util.LinkedList;
import java.util.List;

public class QueueServer {

public LinkedList<Waiter> init(){
for(int i=1;i<=30;i++){
Waiter w = new Waiter();
w.setNum(i);
w.setFrontNum(i-1);
waiterList.offer(w);
}
return waiterList;
}
