PI should be declared as a constant (please use your own declared constant for this lab, rather than Math.PID) The class contains two constructors - one that set the data properties to the default (assume default radius is 1.0 and the default color is white) and the 2-arg consructor sets the data properties to the values passed in. In addition, add the get/set methods and the find methods given in the UML diagram. (yes, this is a Circle class, but we can still use the data properties to calculate values for a Sphere...)

Explanation / Answer

/************ Circle.java ****************/

public class Circle {
private Double radius;
private String color;
private Double PI = 3.14159;

public Circle() {
radius = 1.0;
color = "White";
}

public Circle(Double radius, String color) {
this.radius = radius;
this.color = color;
}

public Double getRadius() {
return radius;
}

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

public String getColor() {
return color;
}

public void setColor(String color) {
this.color = color;
}

public Double findArea() {

return (double)Math.round(radius * radius * PI * 1000d) / 1000d;
}

public Double findCircumference() {
return (double)Math.round(2 * PI * radius * 1000d) / 1000d;
}

public Double findSurfaceArea() {
return (double)Math.round(4 * PI * radius * radius * 1000d) / 1000d;
}

public Double findVolume() {
return (double)Math.round((4 * PI * radius * radius * radius)/3 * 1000d) / 1000d;
}

}

/********** CircleApp.java ***************/
