Guys/Gals I have the core of the program finished but I just need help creating a default constructor. Here are the details and my code will follow.

Write a program that instantiates a couple of Spheres - one should use the default constructor and one should use the 1-param constructor. Display the volume and surface area of each sphere object.

Attribute for radius. This should be able to hold decimal values.

Default constructor. Sets a default radius of 1.

One-Parameter constructor. Sets the radius to whatever input is passed into this constructor.

getVolume() method - calculates and returns the volume of the sphere.

getSurfaceArea() method - calculates and returns the surface area of the sphere.

//This is my class

import java.awt.*;

public class Sphere

{

double Radius;

}

public void print() {

System.out.println("Enter the Radius:");// Enters a radius saves it in variable and puts it into formula

Radius = SavitchIn.readLineDouble();// Stores User Input

}

public String getVolume()

{

return "Volume: " + 4/3 * Math.PI * Math.pow(Radius, 3);// Takes Radius and puts it into formula that displays the volume

}

public String getSurfaceArea()

{

return "Surface Area: " + 4 * Math.PI * Math.pow(Radius, 2);//// Takes Radius and puts it into formula that displays the Surface Area

}

}

// This is to test it

class Testsphere

{

public static void main(String[] args)

{

Sphere mySphere = new Sphere ();

mySphere.print();

System.out.println(mySphere.getSurfaceArea());// Prints out the Surface Area

System.out.println(mySphere.getVolume());// Print out the Volume

}

}

Any help would be greatly appreciated
