如何在java中创建一个等待对象实例化的方法？

public class MyClass {
    private Object lock = new Object();
    private MyObject myObject;

    public MyObject getMyObject() {
        synchronized (lock) {
            while (myObject == null) {
                try {
                    lock.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            return myObject;
        }
    }

    public void initializeMyObject() {
        synchronized (lock) {
            // 实例化MyObject对象
            myObject = new MyObject();
            lock.notifyAll();
        }
    }
}
