import java.text.DecimalFormat;

public class OrderItem {
    private static DecimalFormat formatter = new DecimalFormat("0.00");	
    private float price;

    public OrderItem(String aDescription, int aPartNumber, float aPrice, int aQuantity) {
	partNumber = aPartNumber;
	description = aDescription;
	price = aPrice;
	quantity = aQuantity;
    }
	
    public int getQuantity() {
	return quantity;
    }
	
    public float getPrice() {
	return price;
    }
	
    public int getPartNumber() {
	return partNumber;
    }

    public float getTotal() {
	return price * quantity;
    }
	
    public String getDescription() {
	return description;
