Java 并发集合的未来：探索新一代并发工具

import java.util.concurrent.*;

public class NextGenerationConcurrencyToolsDemo {

public static void main(String[] args) {
// 使用ExecutorService管理线程池
ExecutorService executorService = Executors.newFixedThreadPool(10);

// 使用Future异步执行任务
Future<Integer> result = executorService.submit(() -> {
// 模拟一个耗时的任务
Thread.sleep(1000);
return 100;
});

// 使用CountDownLatch等待一组任务完成
CountDownLatch countDownLatch = new CountDownLatch(10);
for (int i = 0; i < 10; i++) {
executorService.submit(() -> {
// 模拟一个耗时的任务
Thread.sleep(1000);
countDownLatch.countDown();
});
}
countDownLatch.await();

// 使用CyclicBarrier等待一组线程全部到达某个点
CyclicBarrier cyclicBarrier = new CyclicBarrier(10);
for (int i = 0; i < 10; i++) {
executorService.submit(() -> {
// 模拟一个耗时的任务
Thread.sleep(1000);
cyclicBarrier.await();
});
}

// 使用Semaphore控制线程并发访问共享资源
Semaphore semaphore = new Semaphore(10);
for (int i = 0; i < 100; i++) {
executorService.submit(() -> {
// 模拟一个耗时的任务
try {
semaphore.acquire();
// 访问共享资源
Thread.sleep(1000);
semaphore.release();
} catch (InterruptedException e) {
e.printStackTrace();
}
});
}

// 使用Exchanger在两个线程之间交换数据
Exchanger<Integer> exchanger = new Exchanger<>();
executorService.submit(() -> {
try {
// 线程1向线程2发送数据
Integer data = exchanger.exchange(100);
System.out.println("线程1接收到线程2发送的数据：" + data);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
executorService.submit(() -> {
try {
// 线程2向线程1发送数据
Integer data = exchanger.exchange(200);
System.out.println("线程2接收到线程1发送的数据：" + data);
} catch (InterruptedException e) {
e.printStackTrace
