为什么这个多线程同步方法不能张三与妻子开回掉呀？
package com.ma.money;
public class AccountDemo implements Runnable{
private int money=1500;
@Override
public void run() {
try {
Thread.sleep(200);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
this.Testmoney();
}
public synchronized void Testmoney(){
for(int i=0;i<5;i++){
if(money>0){
System.out.println(Thread.currentThread().getName()+"----"+(money-500)+"---"+i);
money=money-500;
}
}
}
public static void main(String[] args) {
AccountDemo accountDemo=new AccountDemo();
Thread t1=new Thread(accountDemo,"妻子");
Thread t2=new Thread(accountDemo,"张三");
t1.start();
t2.start();
}
}

AccountDemo accountDemo=new AccountDemo();
Thread t1=new Thread(accountDemo,"妻子");
Thread t2=new Thread(accountDemo,"张三");

}
