Question on instantiation?

What is instantiation give an example?

To instantiate is to create such an instance by, for example, defining one particular variation of object within a class, giving it a name, and locating it in some physical place. 1) In object-oriented programming, some writers say that you instantiate a class to create an object, a concrete instance of the class.

What happens during the instantiation?

Each object in the real world can be considered an instance of a particular class. Instantiation is the process of creating an object or real instance from an abstract class. Each object once instantiated then has its own identity, properties, and features.

What is the process of instantiation?

Process Instantiation refers to the action and the rules of creating an instance from a process model. Instantiation requires an initial state to be identified for the newly created instance.

Why do we need instantiation?

Understanding instantiation also gives the user a better knowledge of the object in the codebase in general, helping to clarify the relationship between things such as classes, objects, variables and functions.

Can an object be instantiated?

When you create an object, you are creating an instance of a class, therefore “instantiating” a class. The new operator requires a single, postfix argument: a call to a constructor.

The constructor

The constructor is called at the moment of instantiation (the moment when the object instance is created). The constructor is a method of the class.

Is instantiation a valid relation between classes?

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.

Is it possible to instantiate multiple objects from the same class?

Yes, it is possible, but you must understand the difference between the following two lines of code. This is an example of assignment: var a = 10; A variable can be assigned as many times as you want, but can only be declared once (within a scope).
