Learning a new language is always challenging, whether you are experienced or not.
Java is a widely used language in software development. It is used to create web servers, business applications, and games (like Minecraft). It is especially popular because the same (compiled) code will run the same way on any platform, because it will be run inside a platform called the Java Virtual Machine (JVM), that the developers of the language have created specifically for each category of computer.
To get started, you have to download the latest version of JDK, aka Java SE Development Kit here, which contains everything you will need. You can then start coding in Java with your preferred code editor; if you are not sure what’s best for you, start with Eclipse. Learning how to use Java might be confusing, so reading Eclipse’s FAQs might be helpful
If you want to learn as much Java as possible before the event start, reading the Think Java Version 6 book will give you a very thorough rundown of the language. Read it carefully and do the exercises, and you should be more than ready for the hackathon!
