(a) (b) (c) Write a class called circle that contains: (i) (ii) (iii) (iv) (v) Two private instance variables: radius (of type double) and color (of type String), with default value of 1.0 and "red", respectively. (2 marks) Two overloaded constructors; Set both radius and color to default for first constructor. Use given radius and default color for second constructor. Two public methods: getRadius () and get Area (). Write the main () function for the circle class above. Draw a detail UML class diagram for circle class. (4 marks) (4 marks) (6 marks) (3 marks) Describe why main () function must be public, static and void. (3 marks) State the three pillars of object-oriented programming.
