Q: Modify the Inventory Program to use a GUI. The GUI should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.public class Products

return (vOfI + valueOfRestockFee(p,u,isR));
}
public static double valueOfRestockFee(double p, int u, boolean isR)
{
double percent = 0;
if(isR) percent = (p * u * 5) / 100;
return percent;
}
