Java 中 notify()在最开始和在最后没有区别吗?

    public static class Task implements Runnable {

        private static final Object lock = new Object();

        @Override
        public void run() {
            synchronized (lock) {
                if (...){
                    lock.notify();
                    dosomething();
                }
            }
        }
    }

这两者的结果是一样的,在任何情况下？

    public static class Task implements Runnable {

        private static final Object lock = new Object();

        @Override
        public void run() {
            synchronized (lock) {
                if (...){
                    dosomething();
                    lock.notify();
                }
            }
        }
    }

谢谢
