    What is abstraction in java?

    Abstraction is a process of hiding the implementation details and showing only functionality to the user.

    Another way, it shows only important things to the user and hides the internal details for example sending sms, you just type the text and send the message. You don't know the internal processing about the message delivery.
    Abstraction lets you focus on what the object does instead of how it does it

    There are two ways to achieve abstraction in java

    1. 1. Abstract class (0 to 100%)
    2. 2. Interface (100%)
