The Product class has a productID and a price. It also has a method getProductID() as shown in the code below. public class Product{ private String productID; private double price; public Product(String productID, double price){ //implementation not shown } public boolean canReplace(Product p){ //implementation not shown } //other instance variables, constructors and methods are not shown}public class Widget extends Product{private String productionDate;public Widget(String id, String pd, double price){//to be implemented in part a}}A Widget is a Product and has a productID and price. The productID is a unique string for each product. No two productID's are the same. Given the following code, Product p1 = new Product("341-1101", 129.99);Product p2 = new Widget("82794-mach10q", "12/7", 89.99);Widget w1 = new Widget("123-AB307", "12.7", 109.95);Part A: A Widget is a product. A Widget has an identifier, a productionDate and a Price. The productID of a Widget is the combination of the identifier and productionDate. Product p2 = new Widget("82794-mach10q", "12/7", 89.99);P2 has an identifier of "82794-mach10q" and productionDate of "12/7". Therefore it's productID is: "82794-mach10q_12/7".The Write the constructor for the Widget class. Part B: The canReplace() method determines if one product can be replaced by another. A Product can only be replaced when the identifier of the parameter productID is greater than the identifier of the calling object and when the price of the parameter product is greater than the price of the calling object. Thus p1.canReplace(p2) is false because the price of p2 is less than the price of p1.And p2.canReplace(w1) is false because the productID for w1 comes before the productID of p2.But w1.canReplace(p1) is true because the productID for p1 comes after the productID for w1 and the price w1 is less than the price of p1.Write the canReplace() method for the Product class below.
