Hello,
I need to write a program that holds a multiple product inventory. Using an array to store the items. The output should display the product info, one at a time. In addition, I have to include the Total Value of the entire inventory.
My only problem is, the total value of the entire inventory is not coming up.
I really appreciate any help...
Here is the code:
public class InventoryPart2 {
public static void main(String args []) {
DVD myDvd;
myDvd = new DVD(10001, "The Ring", 6, 15.95);
System.out.println(myDvd);
myDvd = new DVD(10002, "X-Men", 7, 17.99);
System.out.println(myDvd);
myDvd = new DVD(10003, "Italian Job", 5, 19.95);
System.out.println(myDvd);
myDvd = new DVD(10004, "Dodge Ball", 8, 16.95);
System.out.println(myDvd);
} //end main
} // end class InventoryPart2
class DVD {
private int itemNum;
private String dvdTitle;
private int dvdStock;
private double dvdPrice;
public DVD(int item, String title, int stock, double price) {
itemNum = item;
dvdTitle = title;
dvdStock = stock;
dvdPrice = price;
} //end four argument constructor
// set DVD Item
public void setItemNum(int item) {
itemNum = item;
} //end method set Dvd Item
//return DVD Item
public int getItemNum() {
return itemNum;
} //end method get Dvd Item
//set DVD Title
public void setDvdTitle(String title) {
dvdTitle = title;
} //end method set Dvd Title
//return Dvd Title
public String getDvdTitle() {
return dvdTitle;
} //end method get Dvd Title
public void setDvdStock(int stock) {
dvdStock = stock;
} //end method set Dvd Stock
//return dvd Stock
public int getDvdStock() {
return dvdStock;
} //end method get Dvd Stock
public void setDvdPrice(double price) {
dvdPrice = price;
} //end method setdvdPrice
//return DVD Price
public double getDvdPrice() {
return dvdPrice;
} //end method get Dvd Price
//calculate inventory value
public double value() {
return dvdPrice * dvdStock;
} //end method value
public String toString() {
return String.format("Item No: %3d Title: %-12s Quantity: %d Price: $%.2f Value: $%.2f",
itemNum, dvdTitle, dvdStock, dvdPrice, value());
}
class Inventory {
DVD movies[] = new DVD[100];
// Add to inventory
public void addToInventory(DVD movie) {
}
// Get inventory value
public double getInventoryValue() {
Inventory myInventory = new Inventory();
myInventory.addToInventory(new DVD(1, "There's Something About Mary", 12, 21.95));
// Print out the inventory total value
System.out.println("Total value of inventory is: " + myInventory.getInventoryValue());
return myInventory.getInventoryValue();
}
}
}
