FAQs on OOP EXERCISE 2 based on tutorial 64 - METHODS Video Lecture - Python Tutorial in Hindi - Back-End Programming
| 1. What is object-oriented programming (OOP)? |  |
Ans. Object-oriented programming (OOP) is a programming paradigm that organizes data and behavior into reusable structures called objects. It focuses on creating objects that can interact with each other to perform specific tasks. OOP promotes code reusability, modularity, and easy maintenance.
| 2. What are methods in OOP? | |
Ans. Methods in OOP are functions or procedures that are defined within a class and are used to perform specific actions or tasks on objects of that class. They encapsulate behavior and allow objects to communicate with each other by invoking methods on other objects. Methods have access to the object's data and can modify it if necessary.
| 3. How do you define a method in OOP? | |
Ans. To define a method in OOP, you need to declare it within a class using the proper syntax. The syntax typically includes the access modifier, return type, method name, and any parameters. For example, in Java, you would define a method like this:
```
public void methodName(parameter1, parameter2) {
// method implementation
}
```
| 4. What is the difference between a method and a function in OOP? | |
Ans. In OOP, a method is a function or procedure that is associated with an object or a class, while a function is a standalone unit of code that can be called independently. Methods are bound to objects and can access and modify their data, whereas functions are not associated with any particular object. Methods are typically used in OOP languages like Java or Python, while functions are more commonly used in procedural programming.
| 5. Can methods have return values in OOP? | |
Ans. Yes, methods in OOP can have return values. The return type of a method specifies the data type of the value that the method will return after execution. If a method has a return type other than `void`, it must use the `return` keyword followed by the value to be returned. The calling code can then use this returned value for further processing.
