Overloaded constructors & getters and setters problem

Question

I'm writing a driver class that generates two cylinders and displays some data. Problem is I don't understand the concept on overloaded constructors very well and seem to be stuck. What I'm trying to do is use an overloaded constructor for cylinder2 and getters and setters for cylinder1. Right now both are using getters and setters. Help would be appreciated.
Instantiable class
public class Silo2
    private double radius = 0;
    private double height = 0;
    private final double PI = 3.14159265;
    public Silo2 ()
        radius = 0;
        height = 0;       
   // Overloaded Constructor?
   public Silo2(double radius, double height) {     
      this.radius = radius;
      this.height = height;
   // Getters and Setters
   public double getRadius() {
      return radius;
   public void setRadius(double radius) {
      this.radius = radius;
   public double getHeight() {
      return height;
   public void setHeight(double height) {
      this.height = height;
   public double calcVolume()
       return PI * radius * radius * height;
   public double getSurfaceArea()
       return 2 * PI * radius * radius + 2 * PI * radius * height;
Driver class I'm not going to show all the code as it's rather long. Here's snippets of what I have so far
So here's input one using setters
validateDouble reads from a public double method that validates the inputs, which is working fine.
public static void main (String [ ]  args)
            Silo2 cylinder1 = new Silo2(); 
            Silo2 cylinder2 = new Silo2();
            //Silo inputs           
            double radSilo1 = validateDouble("Enter radius of Silo 1:", "Silo1 Radius");
            cylinder1.setRadius(radSilo1);
            double heiSilo1 = validateDouble("Enter height of Silo 1:", "Silo1 Height");
            cylinder1.setHeight(heiSilo1);
Output using getters
//Silo1 output
            JOptionPane.showMessageDialog(null,"Silo Dimensions 1 "   +
                '\n' + "Radius = " + formatter.format(cylinder1.getRadius()) +
                '\n' + "Height = " + formatter.format(cylinder1.getHeight()) +
                '\n' + "Volume = " + formatter.format(cylinder1.calcVolume()) +
                '\n' + "Surface Area = " + formatter.format(cylinder1.getSurfaceArea()));How can I apply an overloaded constructor to cylinder2?

Hey man,
My problem is that I don't now how to use an overloaded constructor. I'm new to this concept and want to use an overloaded contructor to display data for cylinder2, and getters and setters to display data for cylinder1.So, again, what in particular is your problem?
Do you not know how to write a c'tor?
Do you not know how to use a c'tor to intialize an object?
Do you not understand overloading?
Do you not realize that overloading c'tors is for all intents and purposes identical to overloading methods?
