  • Q2. Tell me about encapsulation
  • Ans. 

    Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.

    • Encapsulation helps in hiding the internal state of an object and restricting access to it.

    • It allows for better control over the data by preventing outside interference.

    • Encapsulation also promotes code reusability and modularity.

    • Example: In object-oriented programming, classes encapsulate data fields and methods to ope
