JAVA really need help with this question please and thanks! ```java7. Consider the following design for a Product class that keeps track of product inventory:public class Product{ public Product(String name, double qty) {} public double getQty() {} public void reduce(double qty) {} public void increase(double qty) {} private String prodName; private double qtyOnHand; /* Data */}```Write the code for a `main()` method that models the following:A grocer starts the day with 50 Hard Rolls and 25 Soft Rolls. She sells 20 Hard Rolls and 10 Soft Rolls. The next morning about half of the Soft Rolls have turned into Hard Rolls. A shipment of 50 Soft Rolls comes in. She sells 30 Soft Rolls and 20 Hard Rolls. The storeowner wants a printout telling how many of each product she now has on hand.

public class Product { public Product(String name, double qty) { prodName = name; qtyOnHand = qty; } public double getQty() { return qtyOnHand; } public void reduce(double qty) { qtyOnHand -= qty; } public void increase(double qty) { qtyOnHand += qty; } private String prodName; private double qtyOnHand; public static void main(String[] args) { Product hardRolls = new Product("Hard Rolls", 50); Product softRolls = new Product("Soft Rolls", 25); hardRolls.reduce(20); softRolls.reduce(10); softRolls.reduce(softRolls.getQty() / 2); hardRolls.increase(softRolls.getQty()); softRolls.increase(50); softRolls.reduce(30); hardRolls.reduce(20); System.out.println("Quantity of Hard Rolls in hand: " + hardRolls.getQty()); System.out.println("Quantity of Soft Rolls in hand: " + softRolls.getQty()); } }Output
