Solved in 2 steps
- Which of the following are true about abstraction? (Multiple choice can be selected) A It is concealing how something works. B It is the hiding of the actual implementation of codes. C It protects the integrity of data inside the program D It restricts the modification of the values of the variables/field by restricting access to the variables E None of the actual ther choices are correctCreate Class Person with variables weight,height, gender and functions walk() sit(). Ceate another Class Sudent with variable ID,First name, Last name, Graduation and function PrintDetail() Write(). Now create a class GraduationStudent with variables UniversityName, YearGraduation and functions Display(). Note: In both parent classes simply add a printf() statement about the task. In child display function show all data2- Design a class for an airline ticket. Some of the field of an airline ticket are start, destination, date of travel, class, price of ticket, number of people traveling, and name of the primary person. Think about the methods appropriate for the class. Add one method call reserve, which will take details of passengers, start date, starting point, destination and other related attributes and returns flight details. (Python code)
- Using the language of the class, describe a real life object that would be a useful or interesting class in python. Describe what variables it would save, what functions it would have, and either what it would be useful or why you think it would be interesting. In class we created a Dog, Student, and Seat class, and you can use those python files as the basis of your class.Computer Science JAVA 1. Discuss what a programmer-defined class would look like. Provide a code sample for a class that has a constructor, fields, and methods to support your point of view. 2. Discuss what inputs the main( ) class program should have. How will those inputs get passed to an object of the class? Provide a code sample to support your answer.What is the difference between an object and a class? Give some examples.
