Java中的缓冲线程池？

Question

有办法在java中缓冲线程池吗？

示例:我有一个最大大小为3的"BufferedThreadPool“，现在我执行5个线程。前3个线程执行。现在游泳池满了。线程4-5在执行一个线程后得到缓冲，它将执行线程4，在完成下一个线程之后，它将执行线程5，等等。

Answer 1

我想你需要这样的东西：

// initialization of your threads
Runnable[] runnables = new Runnable[5];
for (int i=0; i<5; i++) {
    runnables[i] = new MyRunnable(i);
}

// initialization of thread pool with fixed size 3
ExecutorService executor = Executors.newFixedThreadPool(3);
// passing the threads to the execution threads pool
for (Runnable a: runnables) {
    executor.execute(a);
}

我希望这能帮到你。

Executors.newFixedThreadPool看起来像您要找的东西：https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/Executors.html#newFixedThreadPool-int-
