If another class attempts to create an instance of this class, it will use the
getIn-
stance()
accessor method to obtain the Singleton instance. It is important to note
that the solution code demonstrates eager instantiation, which means that the instance
will be instantiated when the Singleton is loaded. For lazy instantiation, which will be
instantiated upon the first request, you must take care to synchronize the
getIn-
stance()
method to make it thread-safe. The following code demonstrates an ex-
ample of lazy instantiation:
