I'm about to start a Computer Science 1 course that uses Java, so I want to get a head start on learning the basics. I've previously programmed in Python and C, so I'm familiar with fundamental concepts like data types, loops, conditionals, and variables. I'm looking for free websites or resources that are informative, ideally text-based since I prefer reading, but I'm okay with video content too. I'd prefer resources that don't require account creation, although I can accept that if the content is genuinely valuable. Additionally, I recall a site that someone shared that displayed Java tutorials in plain text format with examples and syntax highlighting, without ads—if anyone remembers that, I'd appreciate a link! To give you an idea of what I like, I found beej's programming guides super helpful, but sadly, they don't have one for Java yet.

Have you looked at the Oracle Java Trails? They're a great starting point and teach the programming basics specific to Java. Once you're comfortable, you might also want to explore Spring Boot.
Since you already know basic programming concepts, you’ll find Object-Oriented Programming (OOP) principles in Java to be new territory, especially things like inheritance and encapsulation. YouTube is a good resource for some video tutorials, just search for basic Java content—it can be quite educational! And remember, hands-on practice is where you really learn.
Just a heads up, in my field, we've shifted from Java to Kotlin for mobile app development, so that’s something to consider if you're into that area.
