如何让线程池里面的线程按照顺序执行?
ExecutorService pool = Executors.newFixedThreadPool(10);
for (int i = 0; i < len; i++) {
pool.execute(new Before());
pool.execute(new MyThread());
pool.execute(new After());
} 如何让pool中的三个线程按顺序执行？谢谢

用join()就行了吧
我直接写了3个线程试了下：
Thread t1 = new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("t1...");
}
});
Thread t2 = new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("t2...");
}
});
Thread t3 = new Thread(new Runnable() {
@Override
public void run() {
System.out.println("t3...");
}
});
t1.start();
t1.join();
t2.start();
t2.join();
t3.start();
