JAVA线程池

看看这篇文章，自己实现了线程池

JDK1.5以后实现了自己的线程池管理，贴一个ExecutorService的用法，很简单

 

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class AThread extends Thread {

	@Override
	public void run() {
		for (int i = 0; i < 10; i++) {
			System.out.println(Thread.currentThread().getName() + ", i=" + i);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}

	public static void main(String[] args) {
		
		// 创建容量为2的线程池
		ExecutorService pool = Executors.newFixedThreadPool(2);
		
		// 创建4个工作线程
		AThread t1 = new AThread();
		AThread t2 = new AThread();
		AThread t3 = new AThread();
		AThread t4 = new AThread();
		
		// 把工作线程交由线程池处理
		pool.execute(t1);
		pool.execute(t2);
		pool.execute(t3);
		pool.execute(t4);
		
		// 关闭线程池
		pool.shutdown();
	}
}
