The Java Singleton pattern belongs to the family of design patterns that governs the instantiation process. A Singleton is an object that cannot be instantiated. This design pattern suggests that at any time there can only be one instance of a Singleton (object) created by the JVM. You implement the pattern by creating a class with a method that creates a new instance of the class if one does not exist. If an instance of the class exists, it simply returns a reference to that object

I need my order to be extended please! I've had parents in the hospital and a funeral since Jan. 2018. Also, my equipment is broken for viewing my tapes. I hope you can help me!

Unfortunately you have posted on the FIXYA web site. It is not a site that takes orders or provides equipment for viewing tapes.

Contact whoever you did order from.

Sorry to hear of your family illnesses and troubles.

Trying to restore my dell computer back to the factory setting

Hey anissa singleton,

If you would like to restore your system to Factory Defaults it can be done by pressing CTRL + F11 at the Dell Screen when the computer first turns on. Be sure to press and release the keys at the same time to access it. Sometimes pressing and releasing the keys several times in a row at the Dell screen can make it easier to access. Please be aware that this can take several attempts to successfully access this menu.

Please note that this will remove all the data that has been added on the system.

Good Luck
