If you're interested in learning Java, you've come to the right place. Here's a quick guide to help you get started with Java Core.

First things first, you'll need to download and install the Java Development Kit (JDK) on your computer. The JDK includes the Java Runtime Environment (JRE) and the Java compiler, which you'll need to write and run Java programs.

Once you've installed the JDK, you can start writing Java code. Java Core is the foundation of the Java platform, and it includes the basic language constructs, such as variables, operators, control statements, and loops. You'll want to start by learning the syntax and semantics of the Java language, as well as the object-oriented programming concepts that Java is built on.

There are plenty of online resources available to help you learn Java Core. Here are a few suggestions to get you started:

1. Oracle Java Tutorials - The official Java tutorials from Oracle are a great place to start. They cover everything from the basics of the Java language to more advanced topics like networking and concurrency.

2. Java for Complete Beginners - This free online course from Udemy is a great introduction to Java for beginners. It covers the basics of Java programming, including variables, data types, and control structures.

3. Head First Java - This book by Kathy Sierra and Bert Bates is a popular choice for beginners. It uses a visual, interactive approach to teaching Java, making it easy to understand and remember.

4. And many more resources can be found on YouTube.

As you learn Java Core, you'll want to practice writing code and experimenting with different programming concepts and try to build some projects. (simple to complex)

With a solid understanding of Java Core, you'll be well on your way to becoming a proficient Java programmer. Good luck on your learning journey!
