Default Constructor

Definition

A default constructor is a special type of constructor that is automatically created by the compiler if no other constructors are defined in a class. It initializes the object's instance variables with default values.

Analogy

Think of a default constructor as a pre-made template for creating an object. Just like how you can buy a plain white t-shirt from a store, the default constructor creates an object with initial values already set, just waiting for customization.

Parameterized Constructor: A parameterized constructor is a constructor that takes one or more parameters to initialize the object's instance variables with specific values.

Instance Variables: Instance variables are variables declared within a class and hold data unique to each instance (object) of the class.

Object Initialization: Object initialization refers to setting initial values for an object's instance variables either through constructors or directly assigning values after creating the object.
