What are some examples of encapsulation in programming languages?

Can you explain encapsulation in programming?

Sure! Encapsulation is a fundamental concept in object-oriented programming that restricts access to certain components of an object.

What are some examples of encapsulation in Go?

In Go, encapsulation is achieved through the use of exported and unexported identifiers. For example, a variable starting with a capital letter is exported and accessible outside its package.

How does encapsulation work in other languages like Java or Python?

In Java, encapsulation is implemented using access modifiers like private, protected, and public. In Python, encapsulation can be achieved using naming conventions, such as prefixing a variable with an underscore.

Can you give me a code example of encapsulation in Python?

Certainly! Here's a simple example:

class Car:
    def __init__(self):
        self.__speed = 0  # private variable

    def set_speed(self, speed):
        self.__speed = speed

    def get_speed(self):
        return self.__speed
