Java多线程之join方法示例

执行某个线程thread的join方法，表示当前线程需要等待thread线程执行完成后再继续执行。

public class JoinMethod implements Runnable {

    @Override
    public void run() {
        System.out.println("Sub thread start, thread name is " + Thread.currentThread().getName());
        for (int i = 0; i < 10; i++) {
            System.out.println("i = " + i);
        }
        System.out.println("Sub thread end, thread name is " + Thread.currentThread().getName());
    }

    public static void main(String[] args) throws InterruptedException {
        System.out.println("Main thread start, thread name is " + Thread.currentThread().getName());
        Thread thread = new Thread(new JoinMethod());
        thread.start();
        thread.join();
        System.out.println("Main thread end, thread name is " + Thread.currentThread().getName());
    }

}
