BlockingQueue接口的具体实现类: ArrayBlockingQueue:构造函数必须带int参数以指明大小; LinkedBlockingQueue:若其构造函数带一个规定大小的参数,生成的BlockingQueue有大小限制,若不带大小参数,所生成的BlockingQueue的大小由Integer.MAX_VALUE来决定; PriorityBlockingQueue:其所含对象的排序不是FIFO,而是依据对象的自然排序...

://openjdk.java.net/jeps/312 . The implication appears to be that this would not only eliminate the requirement for all threads to be at a global safepoint, but also reduce the total number of global safepoints arbitrarily injected, as mentioned before, by the JVM. This means that overall...
一、JavaQueue基础 Queue: 基本上,一个队列就是一个先入先出(FIFO)的数据结构 offer,add区别: 一些队列有大小限制,因此如果想在一个满的队列中加入一个新项,多出的项就会被拒绝。 这时新的 offer 方法就可以起作用了。它不是对调用 add() 方法抛出一个 unchecked 异常,而只是得到由 offer() 返回的 false...
