Understanding constructor overloading in a Circle class

Report a typo

Given the definition of a class `Circle` which represents a geometric circle, your task is to instantiate objects in different ways using its constructors. For this class, two constructors are provided - a no-argument constructor which initializes the radius of the circle to 1.0, and another constructor that takes a single argument for setting the radius. Comment on the structure of this class in terms of how it leverages constructor overloading to offer flexibility in object instantiation.

                }
              
                this.radius = r;

                this.radius = 1.0;
              
                return "Circle with radius " + radius;
              
                }
