前端之家收集整理的这篇文章主要介绍了
java – 条件 – 应该在等待之前解锁？，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
你能不能告诉我是否应该在等待条件之前释放锁？
try {
lock.lock();
while (isNotEmpty()) {
condition.await();
}
} finally {
lock.unlock();
}
要么
try {
lock.lock();
while (isNotEmpty()) {
lock.unlock();
condition.await();
}
} finally {
lock.unlock();
}
不,您不需要显式释放锁,等待将
自动释放.从
javadoc：
The lock associated with this Condition is atomically released and the
current thread becomes disabled for thread scheduling purposes[…]
和：
The current thread is assumed to hold the lock associated with this Condition when this method is called.
