So what is Java? 

Java is an object oriented programming language used just about everywhere in the world of computing. Android apps, many financial groups, Airbnb and Uber all use Java. 

Java is an excellent place to start if you’re new to programming, because it’s explicit and easy to read, its strict coding rules leave less room for mistakes, and its syntax is similar to other languages, making for a smooth transition if you’re planning to round out your education by learning other programming languages in the future.

How do I get the most out of a Java course?

The best way to learn new coding skills is by doing. Coding takes much more than reading and memorization. It’s something you’ll want to play around and experiment with after you learn each new skill. Prioritize using exercises as a way to get the most out of your class.

It’s also very important to pay attention when learning the fundamentals. The more advanced aspects of coding will come easier if you know the basics like the back of your hand.
