Overloading constructors

Definition

Overloading constructors refers to the ability to have multiple constructors in a class, each with a different set of parameters. This allows objects to be created with different initial states or configurations.

Analogy

Think of overloading constructors like ordering a pizza. You can order a basic cheese pizza, or you can choose to add toppings like pepperoni, mushrooms, or extra cheese. Each combination creates a different version of the pizza, just like each constructor creates a different version of an object.

Related terms

Method overloading: This is similar to constructor overloading but applies to regular methods instead. It allows multiple methods in a class with the same name but different parameter lists.

Default constructor: A default constructor is a constructor without any parameters. It is automatically provided by Java if no other constructors are defined in the class.

Parameterized constructor: A parameterized constructor is one that takes one or more parameters. It allows you to initialize instance variables with specific values during object creation.
