Java – Ways to Generate Unique Ids in Java

	/**
	* The object creation time can be set to object’s identifier property.
	* For this purpose, System.currentTimeMillis() can be used. However,
	* two or more objects may be created in a single millisecond.
	* In this case, these objects will have the same id which is unacceptable.
	* One way to cope with this problem is to use System.nanoTime().
	* Even if the nano time is the smallest interval we can use, it does not
	* also guarantee the uniqueness. To provide unique time stamps,
	* I got help from AtomicReference class as follows.
