Key Concepts

new Operator

The new operator is used in many programming languages to construct new objects dynamically. It handles both memory allocation and the calling of a constructor to set up the object properly. Understanding the correct syntax for using the new operator is crucial for correctly instantiating objects in a client class.

Constructor

A constructor is a specialized method within a class that is automatically invoked when an object is created. Its purpose is to initialize the object's state, often by setting initial values for attributes. Constructors ensure that the object starts in a well-defined state and can make use of parameters to customize the initialization process.

Object instantiation

Object instantiation is the process of creating a new instance of a class in object-oriented programming. This involves allocating memory for the object and initializing its properties by calling a special method, typically a constructor. The concept is central to OOP as it enables encapsulation and the creation of multiple objects from a single class template.
