Do you have a concrete example to support the use of the word "oops"?

Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…

1. Use Argo UML to draw the following: a. Class 'Employee that has the following attributes (name, address, phone). b. Class 'Teacher' that has attributes (ssn, email, title) and one method to print the previous information. c. Class 'course that has attributes (Id, name, code, detail) and one method to print the previous information. d. Make relationship between the class Teacher' and 'course' as many teachers teaches many courses. e. Class 'Teacher' inheritance its information from class 'Employee'.

Complete the following class diagram with the correct associations to make our object-oriented parking system complete.

a.For each test case, is it directly reusable for class B? Write your answer in column 4 of the above table. b.Do you need to consider more test cases in order to test class B more thoroughly? If so, add your test cases to the above table.

So what is the function of a class, object, and method? Please explain using examples and in simplest detail possible

please take note of the following correction: The sentence "Please note that +/- sign represents private and public modifiers respectively" should be "Please note that +/- sign represents public and private modifiers respectively.
