Java Timer 对象创建后使用Timer更改其属性!!!

首先来个简单那的实例:
package cn.vicky;
import java.util.Timer;
import java.util.TimerTask;
public class MyTimer {

private int i = 1;

private void change(long time){
System.out.println("one : " + i);
final Timer timer = new Timer();
timer.schedule(new TimerTask(){
@Override
public void run() {
System.out.println("run " + i++);
if (i != 5) {
timer.cancel();
}
}

}, 10000,1);
System.out.println("two : " + i);
}
public static void main(String[] args) {
MyTimer mytimer = new MyTimer();
mytimer.change(0);
}
}

我们以一个实例思考,车站,每辆车只能停靠10分钟就必须出站.传统方式,我们是以车站为单位,通过多线程来控制每辆车的出站情况!
package cn.vicky;
import java.util.Date;
/**
*
* @author Vicky
* 公交汽车
*/
public class Bus {

private String name = "";

private boolean inStation = true;
/**
* 公交汽车在车站中只可能呆10分钟,然后公交就开走,相对于公交车站,公交10分钟后就为空!
*/
public Bus(String carName) {
this.name = carName;
System.out.println(new Date() + " : a car["+ name +"] into the bus station !");
}
public void setInStation(boolean inStation) {
this.inStation = inStation;
}
public boolean isInStation() {
return inStation;
}

public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((name == null) ? 0 : name.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
final Bus other = (Bus) obj;
if (name == null) {
if (other.name != null)
return false;
} else if (!name.equals(other.name))
return false;
return true;
}
@Override
public String toString() {
return "Bus [" + name + "] :: " + (inSta
