ExecutorService测试04

package t1;

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

public class TestThread16 {

public static void main(String[] args) {
ExecutorService es = Executors.newFixedThreadPool(3);
System.out.println(Runtime.getRuntime().availableProcessors());// 可用线程数,加上主线程共4个
for (int i = 0; i < 10; i++) {
final int index = i;
es.execute(new Runnable() {
public void run() {
System.out.println(Thread.currentThread().getName() + " " + index);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
}
}
}

结果：

固定线程个数，任务执行完成后，线程回收到线程池，程序不会终止
