Constructors can also be overloaded, just like methods.

Constructor overloading allows you to create objects in different ways.

The MyClass class has four overloaded constructors, each initializing the object differently.

The appropriate constructor is called based on the parameters provided in the new statement.

Constructor overloading provides flexibility in constructing objects.

A common reason for constructor overloading is to allow one object to initialize another.

Providing a constructor that uses one object to initialize another can be efficient, as shown in the example.

In the case of constructing s2, the sum does not need to be recalculated, as it is copied from s1.

Even when efficiency is not a concern, having a constructor that copies an object can be useful.
