模拟多个线程并行执行任务,假设我们有多个线程,每个线程执行一些任务,主线程会等待这些任务完成之后才继续执行。 import java.util.concurrent.CountDownLatch; public class CountDownLatchExample { public static void main(String[] args) throws InterruptedException { // 创建一个 CountDownLatch,计数器为 3,表示需...
代码案例下面是一个简单的代码示例，演示了如何使用CountDownLatch，如下代码：import java.util.concurrent.CountDownLatch; publicclassCountDownLatchExample{ // 定义一个包含3个计数的CountDownLatch privatestaticfinalint WORKER_THREADS = 3; privatestaticfinal CountDownLatch latch = new CountDownLatch(WOR...
下面是一个简单的代码示例,演示了如何使用CountDownLatch,如下代码: import java.util.concurrent.CountDownLatch; public class CountDownLatchExample { // 定义一个包含3个计数的CountDownLatch private static final int WORKER_THREADS = 3; private static final CountDownLatch latch = new CountDownLatch(WORKER...
下面的示例展示了 CountDownLatch 的基本用法: importjava.util.concurrent.CountDownLatch;publicclassCountDownLatchExample{publicstaticvoidmain(String[] args){finalintthreadCount=3;CountDownLatchlatch=newCountDownLatch(threadCount);for(inti=0; i < threadCount; i++) {newThread(newWorker(latch, i)).s...
