public class Inventory {
private static int itemCount = 0;
private static double totalValue = 0.0;
private int quantity;
private double unitPrice;
public Inventory(int qty, double price) {
quantity = qty;
unitPrice = price;
itemCount++;
totalValue += quantity * unitPrice;
}
public void restock(int additionalQty) {
quantity += additionalQty;
totalValue += additionalQty * unitPrice;
}
public void adjustPrice(double newPrice) {
totalValue = totalValue - (quantity unitPrice) + (quantity newPrice);
unitPrice = newPrice;
}
public static double getTotalValue() {
return totalValue;
}
}
