// The standard idiom for calling the wait method in Java
synchronized (sharedObject) {
while (condition) {
sharedObject.wait();
// (Releases lock, and reacquires on wakeup)
}
// do action based upon condition e.g. take or put into queue
}
⑤多线程中测试某个条件的变化用 if 还是用 while?
说是要把if换成while的理由,应该是wait线程被唤醒之后,会继续从wait那里往下面执行,如果是if的话,就会直接往下面执行,不会再判断if的状态了;但是如果是while的话,从wait那里往下面执行,然后还会判断while中的条件,如果==0的话,还是会继续阻塞,如果是>0,则会执行while语句块外面的remove吧?!其中关键就是被notify唤醒之后,是否会执行条件判断
