Question 5. Legacy Code: You have been asked to improve a codebase which is two years old. Which ONE of these sets of steps would you choose to improve this legacy code? a) 1. Draw a class diagram of the system. 2. Write the minimum necessary classes from the diagram. 3. Write the tests. 4. Write just enough code to allow the tests to pass. 5. Refactor to simplify and neaten the code, remove duplication etc. b) 1. Pull the legacy code and make a repository. 2. Swap the dependencies. 3. Refactor and debug code. 4. Write tests to cover the legacy code. 5. Create fake/dummy objects for components such as databases. 6. Push the maintained code to production. c) 1. Write the tests. 2. Refactor to simplify and neaten the code, remove duplication etc. 3. Draw a class diagram of the system. 4. Write the minimum necessary classes from the diagram. 5. Write just enough code to allow the tests to pass. d) 1. Pull the legacy code and make a local repository. 2. Write test to cover the legacy code. 3. Create fake/dummy objects for components such as databases 4. Swap the dependencies. 5. Refactor and debug. 6. Push the maintained code to production.

Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note. The note’s value is an integer. it is specified by counting how far the note lies above or below the A note that orchestras use in tuning ( https://en.wikipedia.org/wiki/A440_(pitch_standard) if needed to check ) . In counting "how far", you should count every key, both the white and black notes on a piano. So the A note above Middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz) quarter note. Include methods to set a note to a specified length and value. Write methods to retrieve information about a note,…
Help, I making a elevator simulator. I have to use polymorphism and object oriented programming to write this code. Can someone please help me improve this code I have. The remaining code is in the pictures. Any help is appreciated. Thank You! The simulation should have 4 types of Passengers: Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements. VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators. Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators. Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. The simulation should also have 4 types…

A lot of these patterns feel very powerful and useful for abstracting and re-using code. Although, I am curious to know as to the extent in which a class "should" be extended in order to prevent unwanted bugs or over-use of a base class that could lead to a chain of inheritance that becomes too brittle.?
3.Study the following class diagram and answer the questions: Teacher Main a. Develop class (Teacher) with the following: Fields or states: Id, Name,Specilization. Methods or behaviurs : getlD(), getName(. getSpes(). b. Inside the class (Main) create an array of type Teacher and add 3 objects of Teacher inside it Print out the Id of first object. Print out the Name of second object. Print out the specilization of third object. Print out all information for all objects stored using for each.
- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True False
