This article mainly shows you the difference between node.js and java. The content is simple and clear. I hope it can help you solve your doubts. Let me take you to study and learn the article "what's the difference between node.js and java".

Differences: 1. Java is a programming language, while "node.js" is a JavaScript running environment based on Chrome V8 engine; 2. Java is a server-side language, and "node.js" can be used effectively on both the client side and the server side.

This article operating environment: Windows10 system, nodejs version 12.19.0, Dell G3 computer.

What's the difference between node.js and java?

Node.js was released in May 2009 and developed by Ryan Dahl. It is a JavaScript runtime environment based on Chrome V8 engine. It uses an event-driven, non-blocking I-peg O model to let JavaScript run on the server-side development platform. It makes JavaScript a scripting language on a par with PHP, Python, Perl, Ruby and other server-side languages.

Java is an object-oriented programming language, which not only absorbs the advantages of C++ language, but also abandons the concepts of multi-inheritance and pointers which are difficult to understand in C++, so Java language has two characteristics: powerful and easy to use. As the representative of static object-oriented programming language, Java language perfectly implements the object-oriented theory and allows programmers to carry out complex programming in an elegant way of thinking.

The difference between nodejs and java

1), Node.js is faster than Java:

Node.js development is fast, the efficiency of running is relatively high, but if the project is large, it is easy to mess up, and javascript is not a static type language, so you don't know the type error until run time, so after writing too much, you will inevitably have the situation that you know there is something wrong but you can't find it, so the test has to be better and more detailed.

Java development is slow, but if the project is large and complex, it is not easy to mess up with java, and it is easier to manage than node.js.

2) both front and back ends of Node.js use Javascript, which represents the trend of future development, while java is the most popular server-side programming language.

3), Node.js and Java EE-- are interpreting languages and compiling languages.

Node.js solves problems 20% faster than Java EE, and an interpreted language is as fast as a compiled language in a VM, which is absolutely impossible without years of optimization.

4) Java is a programming language, while NodeJS is a JavaScript running environment based on Chrome V8 engine written in Crecore C + +.

5) Java is strictly a server-side language independent of browsers, while Node JS can be used effectively on both the client side and the server side.

What are the advantages of Java. Simple, as long as understand the basic concepts, you can write applications suitable for a variety of situations; 2. Object oriented; 3. Distributed, Java is a network-oriented language; 4. Robust, java provides automatic garbage collection for memory management to prevent programmers from making mistakes when managing memory. ; 5. Security, Java used in the network and distributed environment must prevent the invasion of viruses. 6. Architecturally neutral, as long as the Java runtime system is installed, it can run on any processor. 7. Portability, Java can be easily ported to different machines on the network. 8. Interpretation execution, Java interpreter directly interprets and executes Java bytecode.
