Question

Create a class named TestCircle whose main() method declares several Circle objects. Using the setRadius() method, assign one Circle a small radius value, and assign another a larger radius value. Do not assign a value to the radius of the third circle; instead, retain the value assigned at construction. Display all the values for all the Circle objects. Save the applicationas TestCircle.java.

Answer 1

public class Circle {
	int radius;


	public Circle() {


	}


	public Circle(int radius) {
		this.radius = radius;
	}


	public void setRadius(int radius) {
		this.radius = radius;
	}


	@Override
	public String toString() {
		return "Circle [radius=" + radius + "]";
	}
}

public class TestCircle {


	public static void main(String[] args) {
		Circle circleOne=new Circle();
		circleOne.setRadius(3);
		Circle circleTwo=new Circle();
		circleTwo.setRadius(7);
		Circle circleThree=new Circle(5);
		System.out.println("Circe one has radius: "+circleOne.radius);
		System.out.println("Circe two has radius: "+circleTwo.radius);
		System.out.println("Circe three has radius: "+circleThree.radius);
	}
