- Explaining the following concepts of Object Oriented Programming with some sample codes using the python programming language and explain each field in more details: • Classes• Objects• Inheritance• Encapsulation• Polymorphism• InterfacesEncapsulation and polymorphism, both object-oriented ideas, are linked with object models.Object-oriented ideas such as encapsulation and polymorphism are linked with object models.
- Object-oriented concepts like encapsulation and polymorphism, and object models, are intertwined.Define method overriding in object-oriented programming. Explain how it differs from method overloading, and provide a code example in a programming language of your choice.Questions:Please answer the following questions:1. Object-oriented programming uses classes and objects. What are classes and what are objects? What is the relationship between classes andobjects?2. Explain Field and method declaration with example.3. How can we access the class members?4. Explain static members and static methods.5. Explain method overloading with example.
- Encapsulation, polymorphism, and object models are all linked in object-oriented programming.Question 2: Recall and apply the concepts of object oriented programming (Java) (iii) We have to calculate the percentage of marks obtained in three subjects (each out of 100) by student A and in four subjects (each out of 100) by student B. Create an abstract class 'Marks' with an abstract method 'getPercentage'. It is inherited by two other classes 'A' and 'B' each having a method with the same name which returns the percentage of the students. The constructor of student A takes the marks in three subjects as its parameters and the marks in four subjects as its parameters for student B. Create an object for eac of the two classes and print the percentage of marks for both the students.Please answer the following questions:1. Object-oriented programming uses classes and objects. What are classes and what are objects? What is the relationship between classes and objects?2. Explain Field and method declaration with example.3. How can we access the class members?4. Explain static members and static methods.5. Explain method overloading with example.
- Given a parent class "Standard Calculator" consisting of one child class "Scientific Calculator". Create the required parent class and child class using(Object-oriented programming concept) means to use the python class object to create this relationship. Hints :(use Classes, class variables, objects, methods, constructors, message passing, object arrays, method overloading, method overriding) The standard calculator(parent) can perform two types of operations: an addition and a subtraction The standard calculator(child)is capable of inputting only two integers. But the scientific calculators(child) can also interpret decimal values. The scientific calculator(child) is capable of four operations: addition, subtraction, cosine and sine of values. Create 100 objects for your scientific calculator(Child) to enable each object to perform two additions at a time. The values passed to the addition operation are upon your choiceExplain the potential issues and pitfalls associated with method overriding in object-oriented programming.Explain the concept of method overriding in object-oriented programming.
