Tip #7: Basic OOP in Java

Do you know the 4 principles of Object Oriented Programming (OOP)? Can you give examples in Java?

Here is:

1. Inheritance: In Java, all classes inherit from Object.

2. Encapsulation: Private fields and public methods - get and set.

3. Polymorphism: If you create a class and override a method ( remember equals and hashCode tip ? )

4. Abstraction: Interfaces define methods but not the actual implementation.

Now you know the basics. Go deeper!

Happy coding!
