Hi Am working on s shape inheritance hierarchy project where we are supposed to define 2d or 3d shapes then use a few examples e.g circles or spheres to calculate areas and volumes of the 2d and 3d shapes respectively. Everything is working fine it compiles and builds successfully but I am unable to calculate the area and the volume of the 3d objects could someone please help? here is my code
// Exerciae 10.9: SphereShape.java
// Sphere Shape class extends ThreeDimensionalShape.
public class SphereShape extends ThreeDimensionalShape
{
private double radius; // sphere radius
// constructor
public SphereShape(double radius )
{
super("SphereShape");
this.radius = radius;
@SuppressWarnings("LocalVariableHidesMemberVariable")
double volume = ( 4.0 / 3.0 ) * Math.PI * Math.pow( radius, 3 );
// end method sphereVolume
@SuppressWarnings("LocalVariableHidesMemberVariable")
double area = 4 * Math.PI * (radius*radius);
// end method sphereVolume
} // end constructor
// return String representation of Sphere object
public String toString()
{
return String.format( "This is a sphere. It's radius = %f. It's volume = %f\n", radius, volume);
} // end method toString
} // end class SphereShapeI have attached the whole project if you need to reference other classes.
