问题描述

多个多线程类按顺序执行

第一次玩多线程，看代码。
public class Test {
public static void doSomthing(){
System.out.println("11111111111");
}

public static void main(String[] args) {

    System.out.println("调用线程1方法...");
    TestThread1 testThread1 = new TestThread1();
    testThread1.doSomething();

    System.out.println("调用线程2方法...");
    TestThread2 testThread2 = new TestThread2();
    testThread2.doSomething();

    System.out.println("其他方法.....");
    doSomthing();
}

}
需求是：main里面的3个方法，要按顺序执行。

public class TestThread1 implements Runnable{

public void doSomething(){
    ThreadPool pool = new ThreadPool();
    for (int i = 0; i < 10; i++) {
        pool.addThread(new TestThread1());
    }
    pool.shutdonw();
}

public void run() {
    System.out.println("这是线程1...");
    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

}
TestThread1 和 TestThread2 是一样的。

public class ThreadPool {
private Integer POOL_SIZE = 2;
private ExecutorService pool = Executors.newFixedThreadPool(POOL_SIZE);
private ThreadCallback callback = null;
private ThreadMonitor monitor = null;

public ThreadPool() {
}

public synchronized void addThread(Runnable thread) {
    pool.execute(thread);
}

public synchronized void setCallback(ThreadCallback callback) {
    if (monitor == null) {
        this.callback = callback;
        monitor = new ThreadMonitor(pool, callback);
        Thread thread = new Thread(monitor);
        thread.start();
    }
}

public synchronized void shutdonw() {
    pool.shutdown();
}

public synchronized boolean isTerminated() {
    return pool.isTerminated();
}

}
ThreadPool是别人写的，
求大神啊！~~

需求是：main里面的3个方法，要按顺序执行。
就是
testThread1.doSomething();
完成后执行testThread2.doSomething();
完成后执行doSomthing();

解决方案二：

需要自己做线程同步 这样才可以控制线程执行顺序
