java.* libraries were supposed to have been core libs, and javax.* to be standard extensions with the possibility of promotion to core libs (i.e., classes in javax libs could be promoted to java namespaces). However, this showed a certain lack of foresight by not considering the fact that moving the namespaces would require everyone using the classes to change their references-- the criterion for promotion being the adoption rate of the library also guaranteed that the impact to existing code would be the greatest for any functionality promoted. Nowadays, the difference is largely academic since the widely adopted javax.* libs are included in the core download, but the namespaces aren't changed. In practice, it's more important what is in the JRE download than what namespace something is in.

What is the difference between user defined class and built in class?
A built-in class is one that is provided by the Java vendor (those that follow the Java specifications will have at least the ones mentioned by the Java Documentation), while a user-defined class is one that is written by any third-party developer (either a library that a developer is using, or the code written by the developer themselves). You can easily identify which code is which by looking at the package name: java.*, sun.*, and javax.* namespaces are all built-in classes, while com.* namespaces are user-defined classes.
What do you mean by java?
Java is an object-oriented programming language which is generally designed either to be compiled to native (machine) code or to be interpreted from source code at runtime. Java is intended to be compiled to a bytecode, which is then run (generally using JIT compilation) by a Java Virtual Machine. IT DESK training course is designed in such a way that it provides a proper understanding of Java Programming along with different features like file handling, string handling, threading, etc. Java is platform-independent and is used to develop Console Applications, Desktop Applications, and Web Applications. Java also supports multithreading which helps it to perform multiple tasks at the same time. IT DESK promotes the students to do Internships and all the Training are given on the latest version of Java. IT DESK certificate is industry-recognized and lets you find the best job opportunities in the field of programming.
What is the Difference between core java and java?
Core Java has to do with the basic package of Java objects that are typically used for general desktop applications. These objects come in the 'Standard Edition' of JavaAdvanced Java could actually refer to any advanced topic having to do with Java programming-- and there are many.The other packages that you will typically see being referred to in opposition to Core Java are Enterprise Java and Micro Edition. Enterprise Java is largely business and network oriented, and Micro Edition is what is typically used for hand-held devices.The difference is that core java is the fundamental for java that will be used in any java technology without this no one can jump on any advance java technology.Where as advance java is specialisation in some domain, such as networking, web, DCOM or database handling.And more over core java packages are always started with "java"e.g.java.lang.....where as advance java are always with "javax"e.g.javax.servlet....Core Java uses the console for Input and output i.e - DOS PromptAdvanced Java is more on the GUI side with a Window,Buttons,Frames,TitleBar,etc.and is used to create more client-server based applications and applets.
