Question: Explain the Encapsulation principle.

Answer: Encapsulation is a process of binding or wrapping the data and the codes that operates on the data into a single entity. This keeps the data safe from outside interface and misuse. One way to think about encapsulation is as a protective wrapper that prevents code and data from being arbitrarily accessed by other code defined outside the wrapper.

Encapsulation is the ability to hide implementation details by making class members(instance variables & methods) private or protected. So that you can make changes in your implementation code without breaking the code of others who use your code is a key benefit of encapsulation. Source: CoolInterview.com
