Analyze the below program, and fill the correct code so that it produces the below output: 0 101class Book { private int bookId; private double bookPrice; public int getBookId() { return bookId; } public void setBookId(int bookId) { this.bookId = bookId; } public double getBookPrice() { return bookPrice; } public void setBookPrice(double bookPrice) { this.bookPrice = bookPrice; }}public class Test { public static void main(String a[]) { Book bobj=new Book();  blank  blank  blank }}Note : Same drag option can be used multiple times. Analyse and use the correct optionSystem.out.println(bobj.getBookPrice()); bobj.setBookId(101); System.out.println(bobj.getBookId());

Problem StatementImplement a product inventory system for an e-commerce application. Your task is to create a Product class to represent individual products. The Product class should include the following attributes: id (integer): A unique identifier for each product.name (string): The name of the product.price (double): The price of the product.quantity (integer): The quantity available in stock.Your goal is to overload the = operator to enable the assignment of one Product object to another. When you assign one Product to another, it should copy all the attributes, creating a deep copy of the object.Input format :The first line of input consists of an integer representing the product ID.The second line of input consists of a string representing the product name.The third line of input consists of a double value representing the product price.The fourth line of input consists of an integer value representing the product quantity.Output format :The program displays the following information:The details of the original product(Product 1 details), including ID, name, price, and quantity in separate lines.The details of the copied product (Product 2 details), including ID, name, price, and quantity in separate lines.Refer to the sample outputs for the formatting specifications.Code constraints :Price is printed as such without any specific precisions.Sample test cases :Input 1 :1Widget A10.9950Output 1 :Product 1 details:ID: 1Name: Widget APrice: $10.99Quantity: 50Product 2 details (copy):ID: 1Name: Widget APrice: $10.99Quantity: 50Input 2 :102Dell253.65Output 2 :Product 1 details:ID: 102Name: DellPrice: $253.6Quantity: 5Product 2 details (copy):ID: 102Name: DellPrice: $253.6Quantity: 5

Given the following set of classes:public class Customer { private String userName; private String password; public Customer(String userName, String password) { this.userName = userName; this.password = password; } public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public void setUserName(String userName) { this.userName = userName; } public String getUserName() { return userName; }} class CustomerTest { public static void main(String[] args) { Customer testAcct = new Customer("user","pass"); testAcct.setPassword("Java"); System.out.println(testAcct.toString()); }}What does the toString() method need to look like to result in the following output:UserName: userPassword: Javaa.)public String toString() { String state = "UserName: " + userName + "\n"; state += "Password: " + password + "\n"; return state;}b.)public String toString() { String state = "UserName: " + userName + "\n"; state += "Password: " + password + "\n"; return password;}c.)public String toString() { String state = "UserName: " + userName + "\n"; state = "Password: " + password + "\n"; return state;}d.)public String toString() { String state = "username: " + userName + "\n"; state += "password: " + password + "\n"; return state;}
