OOPs 面试题与答案
问题 1. What is Object-Oriented Programming (OOP)?
OOP is a programming paradigm that uses objects to organize code. It involves concepts like encapsulation, inheritance, and polymorphism.
问题 2. Explain the concept of encapsulation.
Encapsulation is the bundling of data and methods that operate on that data into a single unit known as a class. It restricts access to some of the object's components.
问题 3. What is inheritance in OOP?
Inheritance is a mechanism where a new class inherits properties and behaviors from an existing class. It promotes code reusability and establishes a relationship between classes.
问题 4. Explain polymorphism.
Polymorphism allows objects of different types to be treated as objects of a common type. It can take the form of method overloading or method overriding.
问题 5. What is the difference between abstraction and encapsulation?
Abstraction involves hiding the unnecessary details while encapsulation involves bundling the data and methods that operate on the data into a single unit.
