This article will explain in detail what is the difference between java and python, the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

The main contents are as follows: (1) python virtual machine is not as strong as java. Java virtual machine is the core of java. The core of python is that you can easily use C language functions or C++ library.

(2) python is fully dynamic, you can modify your own code at run time, and java can only be achieved through workarounds. The variables of python are dynamic, while those of java are static and need to be declared in advance, so the code hint of java ide is better than that of python ide.

(3), python came into being decades ago, process-oriented is the mainstream decades ago, so there are a lot of programs using process-oriented design method with python, a lot of concepts come from c language, class is added later in python, and java is to achieve C++ without pointers (reference counting used by com components at that time, virtual machine used by java), mainly using object-oriented design methods, and many concepts are oop concepts. Process-oriented, relatively simple and intuitive, but easy to design noodle programs, object-oriented, relatively abstract and elegant, but easy to over-abstract.

(4), in the actual use of python is simple, but to learn to work with python, you need to learn a variety of python libraries, pyhton's strength lies in the library, why the python library is strong, because the python library can use python,c language, C++, etc., and then provide to python use, so no matter gpu operation, neural networks, intelligent algorithms, data analysis, image processing, scientific computing, all kinds of libraries are waiting for you to use. Java does not have as many open source libraries as python, many of which are used internally by commercial companies, or released as a jar package without seeing the original code. Because the python virtual machine is not as good as the support of java (or deliberately designed), it usually uses the source code (linux), or the source code is simply packaged (such as pyexe).

(5), python has a lot of virtual machine implementation, such as cython,Pyston,pypy,jython, IronPython, etc., suitable for business language, or plug-in language, or domain-oriented language, while java because of the huge virtual machine, rarely used for plug-in language, release is not convenient.

(6) java is mainly used in areas with strong business logic, such as mall systems, erp,oa, finance, insurance and other traditional database transactions. Through similar ssh framework transaction codes, it supports commercial databases such as oralce,db2,sql server, and has a strong concept of software engineering, which is suitable for software engineering multi-person development mode. Python is mainly used for web data analysis, scientific calculation, financial analysis, signal analysis, image algorithm, mathematical calculation, statistical analysis, algorithm modeling, server operation and maintenance, automatic operation, strong rapid development concept, suitable for rapid development team or individual agile mode.

(7) the commercialization of java is supported by many companies, such as sap,oracle,ibm, there are commercial containers, middleware, enterprise framework ejb. Python is supported by many open source organizations, such as qt,linux,google, and many open source programs support python, such as pyqt,redis,spark.

(8), the most use of python is script, the most use of java is web,pyhotn glue, which can glue all kinds of irrelevant things together. Java is gay and can form a team of hundreds of people to compete with you through software engineering. However, I think python is still powerful, because it is easy to call c or C++ libraries, but software engineering and commercial operation are not as good as java and are suitable for rapid development.

(9) about money. If you want to write programs and sell software with java, you can use ibm server, oracle database, EMC storage, the price is high, commercial purchasing companies like this high-end. If you want to directly use the program to generate money with python,python can achieve wide customer finance, data back testing, stock speculation, options, gold, bitcoin speculation, hedging arbitrage, statistical arbitrage, there are a lot of open source database, data analysis database, machine learning library can refer to.

(10), java and python can all run on the linux operating system, but many linux can be natively supported and python,java needs to be installed on its own. The reasons why java and python are stronger than c # are greater than those that support linux, osx, unix and arm. The reason java and python are more popular than C++ is that they don't need pointers.

(11) for the mobile Internet, python can only run on Android or ios,java through the runtime to support Android development natively, but not in ios.

(12) for big data, hadoop is opened by java, spark is developed by Scala, and it is more convenient to use python to call spark for reanalysis.

About what is the difference between java and python to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
