JAVA PROGRAMMING: Lesson – Overloading Constructors 1. a .Create a class named Circle with fields named radius, area and diameter. Include a constructor method that sets the radius to 1. Also, include methods named setRadius(), getRadius(), computeDiameter() which computes a circle’s diameter and computeArea which computes a circles area (The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius. b. Create a class named TestCircle whose main() method declares 3 Circle objects. Using the setRadius() method, assign one circle a small radius value and assign another circle a larger radius value. Do not assign a value to the radius of the 3rd circle; instead, retain the value assigned at the constructor. Call computeDiameter() and ComputeArea() for each circle and display the results. Provide your own screen display.

2.Create a class named House that includes data fields for the number of occupants and the annual income as well as methods named setOccupants(), setIncome(), getOccupants() and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and income field to 0. Create an additional overloaded constructor . This constructor receives an integer argument and assigns the value to the occupants field. Create a third overloaded constructor this time, the constructor receives 2 arguments, the values of which are assigned to the occupants and income fields respectively. Create another class named I_house that instantiates the House class and see if the constructors work correctly.
