There are many differences between the two Java versions. One of them is that the advanced version has more features that can be used for more complex applications.

The difference between Core Java and Advanced Java is that the latter provides more features and capabilities. Core Java is a subset of the Java programming language that offers a subset of the capabilities of the entire language. It was designed to be used as an easy-to-learn, easy-to-use, and easy-to-understand foundation for learning other parts of the language. Advanced Java is a subset of the Java programming language that provides more features and capabilities than Core Java.

The core Java basics are the building blocks of the Java programming language. They are the fundamentals that every Java programmer should know. The Java programming language core contains four fundamental elements: variables, expressions, statements and methods.
