Some companies will put "core java" to differentiate from Java EE, but it's still just your basic Java.

blocks|key|1153685|text|我认为当您看到"core+Java“这个短语时，他们谈论的是该语言的基础知识，也许还包括Java+SE的一些知识。我不知道他们为什么要费心把“核心”放在上面。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1153686|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I think when you see the phrase "core Java," they are talking about the basics of the language and maybe some knowledge of Java SE. I don't know why they would bother to put the "core" on there.

According to some developers, "Core Java" refers to package API <code>java.util.*</code>, which is mostly used in coding.

The term "Core Java" is not defined by Sun, it's just a slang definition.

J2ME / J2EE still depend on J2SDK API's for compilation and execution.

Nobody would say <code>java.util.*</code> is separated from J2SDK for usage.

blocks|key|1368865|text|“核心Java”是Sun+Microsystem的术语，用于指代Java+SE。还有Java和Java+(J2EE)。所以这样说是为了与Java和J2EE区分开来。所以我觉得Core+Java只是用来提到J2SE的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1368866|祝您学习愉快！|1368867|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

"Core Java" is Sun Microsystem's term, used to refer to Java SE. And there are Java ME and Java EE (J2EE). So this is told in order to differentiate with the Java ME and J2EE. So I feel Core Java is only used to mention J2SE.

Happy learning!

blocks|key|1153976|text|在简单语言中，核心java代表继承、多态性、抽象、封装、类、对象等概念，这些概念都属于核心java。Core+java代表J2SE。我希望这能消除你的疑虑。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1153977|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Java having 3 category:

J2SE(Java to Standard Edition) - Core Java

J2EE(Java to Enterprises Edition)- Advance Java + Framework

J2ME(Java to Micro Edition)

Thank You..

blocks|key|1153896|text|“核心Java”是Sun的术语，用于指代Java、标准版和一组相关技术，如Java+VM、CORBA等。这主要是为了区别于Java+ME或Java+EE。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1153897|还要注意的是，他们谈论的是一组库，而不是编程语言。也就是说，无论您使用的是什么库，编写Java的底层方式都不会改变。|1153898|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

"Core Java" is Sun's term, used to refer to Java SE, the standard edition and a set of related technologies, like the Java VM, CORBA, et cetera. This is mostly to differentiate from, say, Java ME or Java EE.

Also note that they're talking about a set of libraries rather than the programming language. That is, the underlying way you write Java doesn't change, regardless of the libraries you're using.

Java is programming language but Core java is just a part of java.
Core java is the basic of java. If you are new to JAVA then you have to start with core java. 

Java is basically categories in 3 parts :

1.) J2SE / Core java stands for Java 2 standard edition and is normally for developing desktop applications, forms the core/base API.

2.) J2EE stands for Java 2 enterprise edition for applications which run on servers, for example web sites. (Spring, Struts are the java frameworks mainly used for J2EE)

3.) J2ME stands for Java 2 micro edition for applications which run on resource constrained devices (small scale devices) like cell phones, for example games.

To learn J2EE or J2ME, you should know core java.

<pre><code>Core Java:
It’s a general term used by Sun Microsystems to describe the standard version of Java (JSE). It’s the most basic version of Java which sets the foundation for all other editions of Java plus a set of related technologies such as CORBA, Java VM, etc. Core Java refers to a collection of libraries rather than just the programming language.

Java :
Java is hypothetically everywhere, thanks to its readability and simplicity. From mobile applications to websites, game consoles to datacenters, from mobile phones to the Internet, Java is everywhere. Millions of devices throughout the world use Java as a core programming language. Even all native Android apps come built-in with Java and several companies use Java as server-side scripting language for backend development.

Core java is a sun term.It mentions the USE,it means it contains only basics of java and some principles and also contain some packages details.

When looking at job openings on-line, I noticed that some openings required knowledge of "core Java". What is core java and how is different from java?

What is the difference between java and core java?

服务器

Android

Java

在网上查看职位空缺时，我注意到一些职位空缺需要“核心Java”知识。核心java是什么?与java有什么不同？
