Implement the class diagram and the sequence diagram. [Help modify the source code]

Source Code:

mport java.util.Scanner;

public class Product { private String name; private int productNum; private int barCode; public Product(String p_name, int p_num, int p_bar) { name = p_name; productNum = p_num; barCode = p_bar; } }

public class User { private int id; public User(int a) { id = a; } public void scan() { } }

public class driver { public static void main( String[] args ) { Product p1 = new Product("product01", 012, 0123212); User u1 = new User(01); } }

Just need to know where the System.in and System.out go, Please show execution
