Incredible Resources To Learn Java Online From Scratch in 2022

Java is one of the most popular programming languages in the world today, and for good reason. Java has seen an explosion in usage due to its role as one of the main languages used in Android development, which sees 1 billion new app downloads per month, according to Google CEO Sundar Pichai.

Programmers are constantly picking it as their number one choice from surveys because it has lasted longer than many other languages out there – plus it’s still being updated and supported too.

Given this longevity, its reliability for corporate applications, support from Oracle Corporation, and safety outweigh any other programming language you could try to pick up. This means that if you’re looking for something new to play around with, going from a secondary code base to Java will make your life 10x easier.

Regardless of what coding language takes your fancy – JavaScript, Python, or C. When companies hire Java developers without much experience, they look for certifications and training developer completed.

With all that growth, it’s important to learn Java and start building your own apps right away. The following free resources to learn Java will get you started quickly with learning Java and give you the tools you need to continue your education beyond this list.
