Java is an object oriented computer programming language (OOP) that is both class-based and concurrent. Java is designed to have very few implementation dependencies, thus it’s very flexible as it lets developers write the code just once while being able to run it anywhere making the Java application run on any platform.

Java applications are compiled to bytecode (class file) which run on any Java virtual machine (JVM) regardless of the platform it’s being used on. Java was originally developed by James Gosling at Sun Microsystems then it was acquired by Oracle.

This post is a road map for anyone willing to start learning Java online for free from scratch, the post will present and compare between the best online sources where beginners can start from and follow along, the sources stated in this post are full structured courses so you won’t find a link to a single video or a group of unrelated tutorials.
