This article mainly talks about "what is the difference between Java EE and Java". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what is the difference between Java EE and Java"?

There are three versions of Java: Java SE (Standard Edition), Java EE (Enterprise Edition) and Java ME (Micro Edition).

Among them, Java SE is known as the foundation of Java. The most commonly used place of Java EE in enterprises is the development of the PC side of the website, while Java ME is often used for mobile development, and now the familiar Android system is developed with Java ME.

Java can be compiled or interpreted. Through the compiler, Java programs can be translated into intermediate code-called bytecode-channel-independent code that can be interpreted by Java commentators. After the narrator, each Java byte instruction is parsed and then run on the computer. It only needs to be compiled once, and the run-time interpretation of the program is performed.

Java is different from the general compiling and interpreting computer language. It first compiles the source code into binary bytecode (bytecode), then relies on virtual machines on different channels to interpret the fulfillment bytecode, and then completes the cross-channel feature of "compile once, perform everywhere".

Perhaps a more summing-up expression is that Java cross-channel is the ability to run Java programs on different environments (mainly operating systems)!

This is why Java is so popular, why it is still standing for so many years and has been prosperous for a long time. A word that ignores the channel and crosses the channel must have lasting vitality. As a programmer, choosing Java is far more valuable for long-term career planning than picking other words that cannot be done across channels (including the now very popular HTML5 language, which is also a cross-channel language, "once designed, universally applicable. Once written, arranged everywhere").

Similar Java EE, Java SE and Java ME can be simply summarized into three points: Java SE is software that runs on a computer.

Java EE is used to make websites-(common JSP skills) Java ME is used to make mobile software. However, Java EE is more widely used and more valuable than Java SE and Java ME in Java, so many enterprises will directly require candidates to master Java EE.

Looking back on the results of the past 15 years, Java has always been one of the best. Java now occupies the position previously owned by C language, and C language has always been the most concerned language before Java began to prevail. The TIOBE Index has also declared this year the year of Java speech, which Java won a decade ago. I'm waiting for Java to get another decade of programming language of the year.

At this point, I believe you have a deeper understanding of "what is the difference between Java EE and Java". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
