Constructor Signature

Definition

A constructor signature refers to the unique combination of a class's name and its parameter types. It helps create instances (objects) of that class with specific initial values.

Analogy

Imagine constructors as blueprints for building houses. Each blueprint has its own unique design (class name) and required materials (parameters), allowing you to construct houses with different characteristics.

Default Constructor: A default constructor is automatically created by Java if no constructor is explicitly defined in a class. It has no parameters and initializes the object with default values.

Parameterized Constructor: A parameterized constructor is a constructor that accepts one or more parameters, allowing you to initialize an object with specific values during its creation.

Instance Variables: Instance variables are variables declared within a class but outside of any method. They hold data that is unique to each instance (object) of the class.
