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:
Assume you have a method expecting the superclass's object to be passed as an argument. In this case, if you give it an object of subclass rather than superclass. Is it acceptable? Why or why not? (Write in maximum 5 lines)

E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilıPython Code: Write a class called Person with a constructor that takes two arguments, name and age and the saves these as attributes Write a method in this called print_person that prints out this information the console Confirm that you did it properly by instantiating an object called p1 and calling the method on the object. Lastly, extend the constructor by adding functionality that checks the input name only contains letters (no numbers allowed).
- True or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.can you help me how to test this Part 1: Test Program Write a program to test all test cases outlined in the test plan. For each method (unit) being tested, ensure your client program provides output clearly describing the method being tested along with the expected and actual result. When testing constructors, verify the results by calling an accessor method of the class. When testing mutators, use the accessor method to verify the state change. When a test fails (actual does not match the expected), correct the method code, then re-test. Keep in mind that a poorly written test can produce inaccurate test results. If a test fails, ensure you have written the test correctly before modifying your unit code. Output Requirement For each method (unit), output the method signature. For each test, output the following: Test number Outcome description Expected result Actual result Leave one blank line between each test. Sample StudentGrades(int) Test #1 - Initialize grades array…private float c; private void method2(double y) { c = y; } in another class we created an object of the first class then within in it : tester.method2 (10.0f); are there any errors ? how many errors if there are any and with explanation please.
- java program: take your time to answer it correct please , thank you It is required to develop an application in Java to maintain information about students registered in various courses in a university. Write a class called Course having data members: courseNum (String such as ITCS214), courseName (String such as Data Structures), credits (int), section (int). Include the following public methods in the class: Default constructor (without any parameters), constructor with 4 parameters, set and get methods for all attributes, equals and toString methods. Write a class called Student having following data fields: idNum (long), firstName (String), lastName (String), gender (char), email (String), coursesRegistered (ArrayList of type Course). Note that coursesRegistered is a list of type ArrayList (Java class) in which each element is of class type Course. The coursesRegistered is the list of courses in which the student is currently registered. It has following methods: Default…How do you handle the case of preventing method overriding in a class or method when needed?Indicate whether the statement is true or false. 13. The non-static methods of a class are called instance method. 14. A constructor has no type and is therefore a void method. 15. A class can have only two constructors. 16. In shallow copying, each reference variable refers to its own object. 21. The method finalize automatically executes when the class objects goes out of scope. 22. A mutator method of a class changes the values of data members of the class. 23. In java, the reference this is used to refer to only the methods, not the instance variables of a class. 24. Classes that are defined within other classes are called inside classes. 25. Modifiers are used to alter the behavior of the class 26. A constructor has the same name as the class. 27. Constructors are called like any other method. 28. You can perform some arithmetic operations on class objects.
