Getting missing method error - first attempt at arrays

Question

I'm trying to work with arrays for the first time ever - I understand the concept, but can't quite get the syntax down. Here is the class which won't compile and is giving me a missing method body or declare abstract message - please help me understand what I'm doing wrong.
import java.util.Scanner;
import static java.lang.System.out;
public class Inventory
  //declare and initialize variables
   private int itemNumber = 0;
   private String productName;
   private int stockAmount = 0;
   private double productCost = 0;
   private double totalValue = 0;
   private double totalInventory = 0;
   //initialize scanner
   Scanner input = new Scanner(System.in);
   public Inventory (int itemNumber, String productName, int stockAmount,
           double productCost, double totalValue);
   out.println("Please enter item number: "); //prompt for item number
      itemNumber = input.nextInt();
   out.println( "Enter product name/description: "); //prompt for product name
      productName = input.next();
   out.println("Quantity in stock: ");
      stockAmount = input.nextInt(); // prompt for stock quantity
   out.println("What is the product cost for each unit? ");
      productCost = input.nextDouble(); // prompt for product cost
        totalValue = stockAmount * productCost; //calculate stock value
      } // end calculate stock value
      { //request for inventory details
        out.printf("%s, which is item number %d, has %d pieces currently in " +
            "stock at a price of %.2f each. The total value of " +
            "inventory in stock is %.2f\n.", productName, itemNumber, +
            stockAmount, productCost, totalValue);
      } // end request
  }// end classHere is my main method - I don't think I'm referencing things the way I'm supposed to.
public class Main {
  public static void main(String[] args) { //start main method
        Inventory inventory = new Inventory(); //call Inventory class
        inventory.inventoryInput();
}

LOL - you are right, I don't really know what I'm doing. I don't understand this and am just trying to muddle my way through this whole thing...as you can tell I'm facing many challenges.
Here is how I've changed my main method and the Inventory class - still getting error messages though - any additional hints/suggestions?
Inventory class
import java.util.Scanner;
import static java.lang.System.out;
public class Inventory
  //declare and initialize variables
   private int itemNumber = 0;
   private String productName;
   private int stockAmount = 0;
   private double productCost = 0;
   private double totalValue = 0;
   private double totalInventory = 0;
   //initialize scanner
   Scanner input = new Scanner(System.in);
   public Inventory (int itemNumber, String productName, int stockAmount,
           double productCost, double totalValue)
   out.println("Please enter item number: "); //prompt for item number
      itemNumber = input.nextInt();
   out.println( "Enter product name/description: "); //prompt for product name
      productName = input.next();
   out.println("Quantity in stock: ");
      stockAmount = input.nextInt(); // prompt for stock quantity
   out.println("What is the product cost for each unit? ");
      productCost = input.nextDouble(); // prompt for product cost
        totalValue = stockAmount * productCost; //calculate stock value
      } // end calculate stock value
      { //request for inventory details
        out.printf("%s, which is item number %d, has %d pieces currently in " +
            "stock at a price of %.2f each. The total value of " +
            "inventory in stock is %.2f\n.", productName, itemNumber, +
            stockAmount, productCost, totalValue);
      } // end request
  }// end classMain method
public class TestInventory
    public static void main(String[] args)
    {Inventory[] inventoryArray = new Inventory[3];
     inventoryArray[0] = new Inventory(0, 2541, Radios, 14, 15.95);
     inventoryArray[1] = new Inventory(1, 1685, VCR, 10, 98.95);
     inventoryArray[2] = new Inventory(2, 5872, Clock, 8, 12.95);
     For (Inventory inventory : inventoryArray)
         System.out.println(Inventory);
}
