An example of static binding is method overloading, and dynamic binding is method overriding. Static binding is also called early binding, which happens at compile-time, whereas Dynamic binding is called late binding, which happens at the time of run time. 7. What is static and dynamic binding in OOP?
The ambiguity and complex issues create a diamond problem defined as extending which parent class upon extending multiple classes. C++ supports multiple inheritances, whereas Java doesn’t support them. It creates an ambiguous situation when runtime to decide which class’ behavior has to be executed. Multiple inheritances are the process of extending the behaviors of multiple classes by a single class. Let us now have a look at the advanced OOP Interview Questions. Part 2 –OOP Interview Questions (Advanced) If an abstract class is forced to instantiate an object out of it, a compilation error will be thrown.

An abstract class will not contain implementation code in its base class. Classes created using abstract classes are called derived classes. 5. What is an Abstract class in OOP?Īn abstract class is used to define at least one abstract method, but an object cannot be created from it. In C++, the destructor needs to be called, whereas in Java, it is not needed, and a garbage collection mechanism will handle it. The method will be called explicitly or implicitly based on the programming language used. A Destructor is a method that is invoked when the object is destroyed or when its’ scope is about to end. This is the most common OOP Interview Questions which is asked in an interview. A constructor must not have any return type. The name of the constructor should be the class’s name ideally and may vary depending on the type of programming language. What is a constructor in OOP?Ī constructor is a method used to invoke the object creation process by initializing the object’s state. Let us move to the next OOP Interview Questions And Answer. Another class can extend a class, and it will be called a parent class.
A subclass can have all the properties that its superclass has, whereas the superclass cannot have the subclass’s properties. A class can be a child class, or a parent class depends on its declaration. A Class can have different subclasses and superclasses. An object will always be a specific instance of a class. An object of its class type will have the same properties as defined in the implementation of Class. What is a Class in OOP?Ī Class in Object-oriented Programming is ideally called a template or a blueprint of an object. There are two types of polymorphism which are called runtime polymorphism and compile-time polymorphism. Polymorphism is the process of defining the same method multiple times to utilize based on data types or arguments. The concept of encapsulation is nothing but a Class used to hide the fields that hold data and the methods to perform the functions that can be accessed based on the access modifier. Whatever functionality needed to use can be called by using its method identifier to get the result. Abstraction is the process of concealing complex logic by defining the code in a separate private method by hiding its implementation. The core concepts of OOP are Abstraction, Encapsulation, Inheritance, and Polymorphism. This first part covers basic OOP Interview Questions and Answers. These OOP Interview questions are divided into parts are as follows:īelow are the 10 important 2023 OOP Interview Questions and Answers: Part 1 – OOP Interview Questions (Basic) Here, we have prepared the important OOP Interview Questions and Answers, which will help you succeed in your interview. Every interview is different from the different job profiles, but still, to clear the interview, you need to have a good and clear knowledge of OOP.
