Cylinder surface, area, height etc etc

Hi, im using a code snippet found on this website,

ylinderVolume


A simplistic program to compute the volume of a cylinder when its radius and length are input via MyInput.class

package cylindervolume;
public class CylinderVolume
{
public static void main(String args[])
{
double pi = 3.14;
double radius, length;
System.out.print("Please enter radius of cylinder: ");
radius = MyInput.readDouble();
System.out.print("Please enter length of cylinder: ");
length = MyInput.readDouble();
System.out.print("Volume = " + (radius*radius*pi*length));
}
}

i studied visual basic last semester at university very hard, and know im struggling again with java. Programming is the only module that i struggle with. All of the others, website management, ssadm i can do with ease but this is just imposible to me. So any help would be very appreciated. As well as the volume i have to calculate the surface are, set the height, set the radius of the base and set the center of the base.

Any ideas?

Many thanks.
