Codecademy
When we started Codecademy, our goal was to give anyone in the world the ability to learn the skills they’d need to succeed in the 21st century. We set out to create a new, interactive way of learning — making it engaging, flexible, and accessible for as many people as possible. Since then, we have helped millions of people worldwide unlock modern technical skills and reach their full potential through code.
We want to create a world where anyone can build something meaningful with technology, and everyone has the learning tools, resources, and opportunities to do so. Code contains a world of possibilities — all that’s required is the curiosity and drive to learn. At Codecademy, we are committed to empowering all people, regardless of where they are in their coding journeys, to continue to learn, grow, and make an impact on the world around them.
In this course, we’ll look into how all Objects are related to each other through the concept of inheritance. We’ll also look at how an object can act like two different objects using polymorphism.
Data is only as useful as the database it’s stored in.

Once you have a strong foundation in Java, the next step is going pro. In this skill path, we’ll teach you the advanced coding skills you need to land a job — along with tips and tricks that will help you nail the technical interview. Learn about data structures and algorithms and dive into more advanced topics like algorithmic complexity and dynamic programming.
Continue your Operating Systems learning journey! IO systems are a combination of hardware and software tools that help a user interact with a computer successfully. In this course, you’ll learn about how the operating system interacts with IO hardware and software.
You’ll need to pass a technical interview if you want to be hired for a technical role. Don’t worry — these interviews are pretty predictable, and the same kinds of problems appear again and again. Even if you don’t have a technical interview scheduled just yet, practicing these common problems will help you grow as a programmer and problem solver, and will help you write cleaner and better code.
Ruby is a general-purpose language that is still popular and in high demand in the marketplace, as it’s more commonly used in Rails applications.
