2) 2.1 Show what is printed on the screen when this program is executed. 2.2 Draw UML outline for Circle class given here. ---------------------------------------------------------- public class TestCircle { public static void main(String [] args) { Circle c0 = new Circle(); c0.name = "oval"; c0.radius = 5; Circle c1 = new Circle(); c1.name = "curved"; c1.radius = 15; Circle c2 = new Circle(); c2.name = "elliptical"; c2.radius = 20; System.out.println("Names: " + c0.name + " " + c1.name + " " + c2.name); c1.radius = 13; c0.radius = c2.radius + c0.radius; System.out.println("radius = " + c0.radius + " " + c1.radius + " " + c2.radius); 3 c2.setRadius(25); c2.name = "Bigger elliptical"; System.out.println(c2.getRadius() + " " + c2.name); } } ---------------------------------------------------------- public class Circle { String name; int radius; public Circle(){ } public Circle(int newRadius){ this.name = "default"; this.radius = 1; } public void setRadius(int newRadius){ this.radius = newRadius; } public int getRadius(){ return this.radius; } public double getArea(){ double area = Math.PI * this.radius * this.radius; return area; } } ----------------------------------------------------------

Print output:
