What is the difference between instantiated and initialized? What about creating objects D, E, and F as objectB changes? Nay, nay! It is the conceptual and technical case the "objectA is an instance of a Class" "Instantiation" and "instance of" have precise meaning - an object gets its type, definitions, and values from a Class
Explicit template instantiation - when is it used? - Stack Overflow Explicit instantiation allows reducing compile times and output sizes These are the major gains it can provide They come from the following two effects described in detail in the sections below: remove definitions from headers to prevent intelligent build systems from rebuilding includers on every change to those templates (saves time) prevent object redefinition (saves time and size) Remove
instantiation - What is the exact meaning of instantiate in Java . . . Instantiation is just creating an object from a class as others have said I suspect the confusion comes from "If you want to invoke the methods of local inner class, you must instantiate this class inside the method" That is true but it is oddly worded and suggests they are somehow different

Avoid instantiating a class in java - Stack Overflow To disallow direct instantiation and instead provide a factory method to return and if necessary create instances; Because all the instances are predefined (eg suits in a deck of cards) although since Java 5, typesafe enums are recommended instead; and The class really isn't a class It's just a holder for static constants and or methods
Why am I getting this warning about utility classes in Java Why does it matter if users instantiate a utility class? They will soon find out there is nothing to it and delete the instantiation code On the other hand, a private constructor will be dead code Either it will bring your test coverage down or force you into writing a test (that uses ugly reflection hacks) that tests, well, dead code
