fashion jewelry lots wholesale The most essential difference is that one is that the script can explain the execution, and the other is to compile it to execute.
The same point is that they will be executed in a middle language and will be optimized. However, Java is optimized and efficient.
It Python's object -oriented objects are not exactly the same as Java. Python is more superficial, and Java is much more strict.
The programming style is also essentially different. Python likes to be casual, likes a lowercase, and likes to use a short -term variable. These are violated in Java.
Python is supported by C language library. It is closer to functional programming. At the same time, it also passed C with the bottom layer of the operating system to deal directly. Java is much weaker in this regard. Java is more suitable for websites and distributed computing. Therefore, it is scientifically used on the Internet.
python covered with wide coverage. From education, scientific research, operation and maintenance management, all the websites are available. Mainly focusing on operation and maintenance management. It was originally used for management when it was created. Java was founded to transplant cross -platform, to embed the system. In fact, Java is unsuccessful in embedding the system.
The gramon Python can use variables without a statement. But requesting alignment is very neat. Java is not required neatly, but the variables must be declared defined before they can be used.
Python uses a large amount of useful pointers, which is very flexible. And Java basically uses object -oriented and class operation instead.
Python can directly execute the dynamic code by yourself. Java is more troublesome to implement LoadClass. Not so flexible.

. The Python virtual machine is not Java strong. The Java virtual machine is the core of Java. The core of Python can easily use the C language function or C library.
. Python is full dynamic. You can modify your own code at runtime, and Java can only be implemented by changing methods. Python variables are dynamic, and Java variables are static and need to be declared in advance, so the code prompt function of Java IDE is better than Python IDE.
three, Python has been produced for decades, and the process is the mainstream decades ago. Therefore, there are many procedures for using Python. Many concepts come from C language. Class is in Python. After joining, Java is to achieve C without pointers (references for COM components, virtual machines used in Java), mainly use objective design methods, and many concepts are OOP concepts. For the process, it is relatively simple and intuitive, but it is easy to design face -facing procedures, facing objects, relatively abstract and elegant, but easy to be too abstract.
four, simple entry in Python in actual use, but you need to learn to work with Python, you need to learn various libraries of Python. The strength of Pyhton lies in the library. Why is Python's library strong? , C language, C and other designs, and then provide it for Python, so regardless of GPU operation, neural network, intelligent algorithm, data analysis, image processing, scientific calculations, all kinds of libraries are waiting for you. And Java does not have as many open source libraries as many as Python. Many libraries are used inside the commercial company, or they are just a jar package, and the original code cannot be seen. Python virtual machine does not have the support of Java (or deliberately designed this) because the compilation is not supported (or deliberately designed this). Generally, the source code (Linux) is used to simply use a package (such as pyexe).
. Python has many virtual machines, such as Cython, Pyston, Pypy, Jython, etc., which are suitable for business language, or plug -in language, or domain language. It is inconvenient to publish in the plug -in language.
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 SSH framework transaction code, to commercial databases, such as ORALCE, DB2, SQL SERVER and other support, strong software engineering concepts, suitable for software engineering multiplayer development models. Python is mainly used for web data analysis, scientific computing, financial analysis, signal analysis, image algorithm, mathematical computing, statistical analysis, algorithm modeling, server operation and maintenance, automatic operation, and rapid development concepts. It is suitable for rapid development teams or personal agile models Essence
Seven, Java's commercial company supports many support, such as SAP, Oracle, IBM, etc., there are commercial containers, middleware, and corporate framework EJB. Python's open source organization supports many, such as QT, Linux, Google, many open source programs support Python, such as Pyqt, Redis, Spark, etc.
8. Python's most useful use is the script, Java's most useful use is web, Pyhotn is glue, which can be used together for all kinds of unrelated things. The team and you PK, the commercial atmosphere is heavy. However, I think that Python is strong, because it can easily call C or C libraries, but software engineering and commercial operations are not as good as Java, which is suitable for fast development.
nine, about money.
If you want to write a program to sell software, use Java, you can use IBM server, Oracle database, EMC storage, high price, commercial procurement company likes this tall. If you want to use the program to generate money with Python, Python can achieve wide passenger finance, data recovery, stock speculation, speculation of options, frying gold, frying Bitcoin, hedging, statistical arbitrage, many open source libraries, data analysis libraries, machines, machinery, machinery, machinery, machine The learning library can refer to.
ten, Java and Python can all run in the Linux operating system, but many Linux can natively support python. Java needs to be installed by itself. The reason for Java and Python than C#is greater than supporting Linux, supporting OSX, supporting unix, and supporting ARM. The reason why Java and Python are more popular than C is that no pointers are required.
11. For the mobile Internet, Python can only run in Android or iOS by running libraries. Java natively supports Android development, but cannot be used in iOS.
12. For big data, Hadoop is opened with Java, spark is developed with scala, and Python calls Spark to analyze it. It is more convenient.
wholesale jewelry making supplies catalogs The differences between Java and Python are as follows:
java are simple, object -oriented, distributed, robust, security, platform independence and portability, multi -threaded, dynamic and other characteristics. Java can write desktop applications, web applications, distributed systems, and embedded system applications.
Python interpreter is easy to expand, and new features and data types can be expanded using C language or C (or other languages that can be called through C). Python can also be used for extended programming language in customized software. Python's rich standard library provides source code or machine code suitable for each major system platform.
It want to learn such technologies to recommend Dane Education. The agency creates an original TTS8.0 teaching system, 1V1 supervisor, tracking learning, and has questions to communicate at any time.

wholesale acrylic jewelry 1. Java operating efficiency is higher than Python, and Java has a relatively much data, especially Chinese data;
2, Java version is relatively stable, Python2 and 3 are not compatible. In software engineering and team, Python is more suitable for small development;
4, Python is simpler than Java programming language;
5, Java grammar definition is more complicated, Python grammar is simple and beautiful;
6, Java bias towards business Development, Python is suitable for data analysis;
wholesale jewelry supply distributors china Java is a static type programming language
Python is dynamic type
java has been recognized and widely used in the market for more than 30 years. R nPython's learning cycle is shorter than Java
