What is the difference between polymorphism and encapsulation in programming?

What is the difference between polymorphism and encapsulation in programming?

Polymorphism allows objects to be treated as instances of their parent class, while encapsulation restricts access to an object's internal state.

Can you give me an example of polymorphism in Go?

Sure! In Go, you can use interfaces to achieve polymorphism. For instance, if you have an interface Shape with a method Area(), different structs like Circle and Rectangle can implement this method.

And how does encapsulation work in Go?

In Go, encapsulation is achieved through the use of exported and unexported identifiers. If a variable or function starts with a lowercase letter, it is unexported and only accessible within the package.

Why are both concepts important in programming?

Both concepts promote better code organization and maintainability. Polymorphism allows for flexible code, while encapsulation protects data integrity.
