Well, actually, the concept of Java Core is very vague. Someone believes that this is all what is described in JLS, someone takes SCJP as a basis, someone uses some own metrics. There are generally people who call it Java Fundamentals, and Core also includes OOP, working with collections, and the basics of multithreading. Here everything is very subjective. But I think if you can answer all the questions from this interview, then you can confidently say that you know Java Core.
As part of Bruce Eckel's book The Java Philosophy.
Then it was Horstmann's 2nd volume. It is called Java Core
Probably the answer to this question should first of all include the java syntax and the tools that distinguish this language from other oop programming languages. As mentioned earlier, this is most likely a manifestation of oop in java, for example, multithreading. In general, many books have been written. And very few people can accurately answer this question , you can take books that embrace java and read the sections, it will become approximately clear.
