OOP Concepts in Java

[ASubhan]

Reflect on your experience with object-oriented programming (OOP) in Java. Discuss how concepts like inheritance, polymorphism, and abstraction have helped you in your projects. Share examples and personal insights.

I'm so confused. Is this a homework question?

My answer would be that using those concepts, not in Java development, but OOP in my own language of choice, allows me to organize my code, and roll my own ORM, which maps rows in my database tables with objects. it allows me to do things such as:

// My PHP code
$record_id = $post_obj = new Post(array(
    'title' => 'Hello World',
    'message' => 'This is my message.'
));

And then a new row is created in the database posts table, and the MySQL auto-increment ID is returned.

Not Java, but you get the idea.

I developed a Sudoku app in Python and doing it without using OOP would have been torturous. Using wxPython without OOP would be near impossible.

Also, sorry about the super weird syntax highlighting in my code snippet above. Appropriately so, the platform attempted to apply java syntax highlighting. Inappropriately so, I replied to a java question with PHP code.
