1. 线程池可以节省创建多个线程带来的开销问题. 2. 线程池的参数如下: public ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue) { this(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue, Execut
java5中新增了可变参数,这个可变参数和C语言中的用法是差不多,但实现起来却不一样. 下面我们一起来看看吧. 其实可变参数就是一个数组 class A{ public void func(int... argum){ for(int i = 0;i < argum.length;i++){ System.out.println(argum[i]); } } } 而且定义起来相当的简单,只需要在类型后面打上三个. 就行. 下面来看看具体使用 public class Main { public
