Create instance of class

An instance variable reserves memory for the data your class needs . Let’s assume you want to add a place for a string or int variable. You can use an instance variable to reserve that memory for the lifetime of the object. Each object will receive unique memory for its variables.

The new operator instantiates a class by allocating memory for a new object and returning a reference to that memory. … Note: The phrase “instantiating a class” means the same thing as “creating an object.” When you create an object, you are creating an “instance” of a class, therefore “instantiating” a class.

That is, it is a member of a given class that has specified values rather than variables . In a non-programming context, you could think of “dog” as a class and your particular dog as an instance of that class.

Instantiating a Class 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 name of the constructor provides the name of the class to instantiate.
