- What effect does a primitive "actual parameter" have on a formal parameter? Your answer When can methods access the private instance variables? Your answerIn c++Create a lecturer class with member-data name (name) and department (department). For the Lecturer class, write constructors, get & set methods, and the toString () method, which returns the textual description of the object. Write a Lecture class with data member:- subject (discipline)- weekday (day of the week when it takes place)- hour (start time, integer)- online (boolean value, whether remote or not)- lecturer (object of class Lecturer)For the Lecture class, write:- constructors- get & set methods- method isItMorning (), returning a Boolean value, the result of checking whether the lecture starts at 7-11- give a new implementation of the toString () method so that it returns the text description of the Lecture objectIn the test function main ()1. Create objects of both classes and illustrate the use of all possible methods for them.2. Create an array of Lecture objects and display it on the screen and in a file.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.
- The behaviour of the instances present of a class inside a method is defined by.Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.1. Why do you need to implement all the methods of an interface in class which implements an interface?
