Free Java Courses

Java's free catalog here is small, but each course has a clear place. Start with Codecademy's Learn Java, the one true beginner course in the set: it teaches syntax and object-oriented basics in the browser with instant feedback, so there's no local setup to fight first. Once the fundamentals hold, MIT OpenCourseWare's Software Construction in Java is the credible next step, an intermediate course on writing code other people can actually maintain. The third course tagged Java here, CS50's Introduction to Programming with Scratch, is really a general intro-to-computer-science unit, not Java syntax, so treat it as background rather than a Java lesson. Three courses is the thinnest of the mainstream-language catalogs on this site (Python has thirteen), so plan to pair Java with project work of your own to fill the gaps.
