object.notify() 好像就是每次只唤醒一个在这个object上wait的线程,但是不保证那
个线程被唤醒。 我当时的思路是定义两个object, H和O线程wait 在不同的object上,
这样就可以notify两次H和一次O了。 当时面试官说这种方法可以的, 哎,

实测了一下这个方法,好像不行哦.主要是因为H object thread不能notify O object
的waiting threads.同理O object thread不能notify H object的waiting threads.导
致满足条件的时候,也不能唤醒对方。
还有什么办法吗?

难道不是producer (H), consumer (O) 问题么?
number of slots = 2,
H thread waits when seeing number of full slots = 2,
O thread waits when seeing number of full slots < 2,
when H thread increases full slots by 1, notify() once,
when O thread decreases full slots by 2, notify() twice,
O1, h1, h2,
yes, h1 will wake up O1, so what?, O1 will go to wait again, then h2 will

谁问你notify,当场喷他。这年头谁还用notify,当场反问要求举一个concurrency
package不能实现的例子。

发帖数: 1

这个基本思路是,线程2等待一个信号,线程1发这个信号。
最直接的是用 Condition.signal/await
自己用 Object.notify/wait() 做也简单
(实际上 Thread.join() 就是用 Object.notify/wait 实现的)
java.util.concurrency 很多 class 都可以应用到这个问题上
如 Phaser , 因为这个问题是很多其他问题的一部分。
如果线程间需要传递数据,可以用SynchronousQueue
如果想更底层一点,可以用 LockSupport.park/unpark
前面有个思路是 lock/unlock (Java可以用 Lock class)
也是同样效果。但是JAVA人的习惯是不能长时间的 hold a lock .

我觉得你这个房东不太好打交道。
其实 close 后就 2 months 了,为什么还得去续签 1 年 lease......对大部分人而言,close 后留下半个月或者一个月的时间,还是有必要的,特别是在房子不是 move-in condition 的情况下。
你这 lease 是怎么签的呢?那个房客和你有没有什么书面合同之类,例如 sublet 合约?如果没有,此事和他就没有什么关系了。
但是即使这样,即使你以你的名义续签了一年的合约,我估计你也能合法地跳出来,只是得损失一些米米。仔细阅读你的 lease。我以前租 apt 时,lease 上是这么说的,首先我不能 sublet,但是如果要 move out,我得:
1) notify the renting office (written notice) 2 months in advance, if signed a one-year contract;
OR
notify the renting office (written notice) 1 month in advance, if signed month-by-mon

你找出你当初签的purchase agreement,看看seller disclosure 和buyer inspection
的条款怎末说的。看看在多少天之内,你是可以notify unacceptable condition的。
如果时限还没过,你就notify seller of your objection together with a copy of
the inspection. 然后seller要在一定天数之内(具体看agreement), terminate the
contract and refund earnest money或者 cure the conditions at seller’s
expense (就是seller花钱修好)。
