怎么让一个线程执行好了再执行另外一个线程？

怎么让一个线程执行好了再执行另外一个线程？

[haojia0716]

synchronized

[dengganxia]

另一个线程用Join()方法

[dengganxia]

上面的join应该是小写，不小心打错了

[fengfengye]

也可以sleep（）

[thinkinjava123]

public class JavaThread11 implements Runnable {

	@Override
	public void run() {
		// TODO Auto-generated method stub

	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		Thread1 t1 = new Thread1();
		Thread2 t2 = new Thread2();
		Thread tt1 = new Thread(t1);
		Thread tt2 = new Thread(t2);
		tt1.start();
		tt2.start();
	}

}

class Thread1 implements Runnable {

	@Override
	public void run() {
		synchronized (JavaThreadScheduling.class) {

			for (int i = 1; i < 100; i++) {
				System.out.println(i + Thread.currentThread().getName());
			}
			JavaThreadScheduling.class.notify();
		}
		

	}
}

class Thread2 implements Runnable {

	@Override
	public void run() {
		synchronized (JavaThreadScheduling.class) {
			try {
				JavaThreadScheduling.class.wait();
				for (int i = 'Z'; i < 'a'; i++) {
					System.out.println(i + Thread.currentThread().getName());
				}
			} catch (Exception e) {
				e.printStackTrace();
			}

		}
	}
}

请问我这个应该怎么改？

[dengganxia]

你想先让那个执行？

我想thread1

[dengganxia]

Thread1 t1 = new Thread1();
Thread2 t2 = new Thread2();
Thread tt1 = new Thread(t1);
Thread tt2 = new Thread(t2);
tt1.start();
tt1.join();
tt2.start();
