Proofreading this small Java program

[almina]

I've recently got this new spiffy Java textbook, and upon doing one of the programming projects, it appears that I've encountered a problem. The logic of this program appears to be fine, but something sematically appears to have effected it to produce a non-sensical result.

The purpose of this program is to construct a class which computes the surface area and volume of a sphere, and return the values.

class Sphere
{
	private final double FT = 1.333333;
	private final double PI = 3.14159;
	
	private double diameter;
	private double radius;
	private double volume;
	private double surfaceArea;
	
	public Sphere (double diameterofSphere)
	{
		diameterofSphere = diameter;
	}
	
	public double findRadius ()
	{
		radius = diameter / 2;
		return radius;
	}
	
	public double getVolume ()
	{
		volume = (FT * PI * Math.pow(radius, 3));
		return volume;
	}
	
	public double getSurfaceArea ()
	{
		surfaceArea = (4 * PI * Math.pow(radius, 2));
		return surfaceArea;
	}
	
	public String toString ()
	{
		return "The surface area and volume of your sphere is: " + surfaceArea +
		volume;
	}
}

public class SphereData
{
	public static void main (String[] args)
	{
			Sphere sphere1 = new Sphere(100);
			
			sphere1.findRadius();
			sphere1.getVolume();
			sphere1.getSurfaceArea();
			
			System.out.println (sphere1);
	}
}

However, this is the output:

The surface area and volume of your sphere is: 0.00.0

Thanks for reading. Also, if I'm doing something that's unnecessary, please tell me =)

	public Sphere (double diameterofSphere)
	{
//		diameterofSphere = diameter;
		diameter = diameterofSphere;
	}

From the looks of it, radius = diameter / 2; is dividing nothing by 2.

I think the line diameterofSphere = diameter; needs to be diameter = diameterofSphere

EDIT: Just realised that's what the guy before me was saying

you may want to put a space in your output. At first I thought something was wrong when i saw 0.00.0, 2 decimals in a number O_O
