What skills do you need to become a Java developer?

Great Java developers have a way with numbers and love to solve problems. With your analytical mindset, you should be able to patiently and efficiently seek solutions to customer and organizational problems, without getting stressed or bored. And while Java developers spend a lot of time solo, coding away, they also need great communication skills, as they work with web developers and software engineers. To keep up with the latest technological changes, adaptability is crucial. Detail orientation is important, too, as you’ll be dealing with a lot of numbers and letters—and one small typo can mess up everything.

Java developers can stand out by understanding object-oriented programming, data structures, design patterns, SQL, test-driven development, and garbage collection (AKA managing and freeing up memory).
