Suppose that instead of removing line # 10, we altered line #8 so that the Dos class no longer inherits from Uno, as shown: class Dos: Fill in the blank on line #19 with a line of code that would've worked before the change, but will now cause a runtime error because we altered line #8. obj1 Uno (9) obj2 Dos (12) #8 Enter your answer here # 17 # 18 # 19

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Modify the above code to use the alternative method for multithreading (i.e., implementing the Runnable interface). Name your main class RunnableHelloBye and your subsidiary classes Hello and Goodbye respectively. The fi rst should display the message ‘Hello!’ ten times (with a random delay of 0–2 s between consecutive displays), while the second should do the same with the message ‘Goodbye!’. Note that it will NOT be the main class that implements the Runnable interface, but each of the two subsidiary classes.Write a Bank Account class in python to manage the account of the users. A user can deposit (add money) and withdraw (take money) money from his/her own account based on availability. At the time of account creation, the user has to provide his/her first name, last name, date of birth, NID number, contact number and address. Moreover, the user should deposit a minimum of 1000 taka to create the account. This money will be added to his account. After account creation the bank will give an account number to the user. The user should use this account number to access his account (show current balance, deposit and withdraw)In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes: Employee - This class represent the employee. It needs the following fields exposed via getters and setters: Employee ID (hard code it to 1) First name, last name, middle initial Address, city, zip Phone, email Hourly rate PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters: Pay period Id (hard code to 123456) Employee Id Start date, end date Number of hours PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods: double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…
- In C++ Somewhere on the net, you find a lovely little class designed to help manage a list of temperature values. You think it could be a decent basis for more general purposes, so you download it and begin your enhancements. Here are the links, in case you forgot to bookmark them (*grin*): http://craie-programming.org/122/projects/TempList.h.html http://craie-programming.org/122/projects/TempList.C.html First you'll need to remove all specific references to 'temperature' to make it a genericlist of double data. This may require changes to identifiers, strings, etc. in various places. Next add a method called get_lastwith no input to return [a copy of] the last item currently in the list. (Note that this will not change the list's contents...) Now add a method called delete_last. It will remove the last item from the list. It can be a pure void function — no inputs and no output. (But this one, does change the list's contents! In particular, don't forget to update the sizemember…C++ programming language Images attached are the task and targeted output.

- In this java assignment, we will be creating a pay stub for an employee using classes. Each class must be implemented into their own file, a total of 5 classes/files. We are going to implement the following classes: Employee – This class represents an employee. It needs the following fields exposed via getters and setters: Employee ID (we will need to make this unique, for now, just hard code it to 1). First name, Last name, Middle initial Address, City, Zip Phone, Email Hourly Rate PayPeriod – This class represents an employee’s payment information. An employee will eventually have more than one pay period. It must contain the following fields (exposed via getters and setters): Pay period Id (hard code it for now) Employee Id (who is this for) Start Date, End Date Number of hours PayrollManager – This class provides the functionality we need to compute and display our payroll. It should implement the following methods: double CalculateGrossPay (Employee, Payperiod) – This…Scenario: You are tasked with the development of an E-Scooter ride-sharesystem.
