sterling silver jewelry wholesale Python is getting faster, but the use of Java is more widely used, so the two have their own advantages and disadvantages. Which one to learn should be judged and selected according to their actual needs.
First of all, let's take a look at the characteristics of Java and Python:
java: Highly object -oriented advanced programming language
The original intention of design is "writing a code once, you can use it wherever you can", you can complete any scale, you can complete any scale, you can complete any scale. The task, so it is also a common choice when many companies do business -grade projects.
Python: Advanced programming language with simple grammar
The original intention is "make the code read easier", and let programmers write less code than other languages, and more effort.
In again, look at the three misunderstandings of everyone's generally on Python:
-misunderstanding: Python is easy to learn
"Simple grammar, easy to read and maintain", the summary of the advantages of python is not at all at all. Wrong, many people think that Python is better than other languages. In fact, it is just faster entry. In the actual application process, no one will think that the difficulty of the project is in the language, but the idea of solving the problem.
The misunderstandings: Python later ranked up
The actually born 4 years earlier than Java, and after 2010, big data, artificial intelligence, cloud computing and other fields have emerged. The recruitment of Python talents, the Python surgery industry specializes in the field of follow, not because it is perfect.
Misunderstandings: Python salary is higher
python language follows the fields of artificial intelligence, big data, cloud computing and other fields. It seems that it is the weathervane of future programming languages. We can easily understand through the recruitment software that Python Development Engineers have a monthly salary of 15k-25K, and Java Development Engineers 15K-30K, which is not much different. Language is just a tool. It still depends on your personal qualifications.
In the end of the newcomers who have entered the industry:
If you are only programming enthusiasts, or using programming language as an application tool at work, Python is a good choice. If you want to develop steadily on the road of programmers, it is recommended to learn Java first, and then learn other languages such as Python, C , PHP, etc.
A good programmers will never rely on a language to be black, just eat them! Compatible and stored, touching by bypass, this is the mentality of mature IT practitioners!
It to study systematically, you can examine comparison of popular schools with related majors. Good schools have the ability to independently develop courses in the current needs of enterprises, and can obtain college or bachelor's degree during the school. a bit.
I learn to achieve success! Hope to adopt!
bali shell jewelry wholesale I. Python virtual machine is not Java strong, Java virtual machine is the core of Java. The core of Python is to 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 necklace display The difference between Java and Python is as follows:
1. Java must explicitly declare variable names, while dynamic types of Python do not need to declare variables.
2. Python is a simple language with simple grammar. It can provide excellent solutions by writing script and can be quickly deployed in various fields.
3. Java can create cross -platform applications, while Python is almost compatible with all current operating systems.
4. For beginners, Python is easier to get started than Java, and the code is easy to read.
5. Speed, neither Java and Python are suitable for high -performance calculations, but in terms of performance, Java is still slightly better. Java's efficiency advantages are reflected in the execution of virtual machines. Local machine code, this instant (JIT) compilation makes the performance of Java slightly better than Python, but Python fine -tune the performance to improve Python efficiency.
java and Python are dynamic programming languages. These two languages are associated with openness. Therefore, it is best to keep an open attitude when companies, teams and programmers make decisions. As for which programmer should the programmer choose to compare them by themselves in combination with the above five points, but more programmers seem to be more inclined to Python. After all, Python has better development in the fields of artificial intelligence, data analysis, cloud computing and other fields prospect!
us jewelry house wholesale Java is a senior programming language, with a high penetration rate and rich third -party library. Java has the largest market demand. From web development, network development, APP development to cloud computing applications, Java can be implemented. It is typical. Object -oriented development language, but it also has certain disadvantages, such as the development code is not simple, the development efficiency is low, and the time cost of learning is high.
Python is a potential programming language. The built -in rich and powerful library can achieve strong and complex functions with simple and beautiful code, and easier to learn. Because of its more user -friendly design, Python has been widely used in application. At present, it has been widely used in artificial intelligence, cloud computing development, big data development, data analysis, scientific operations, website development, reptiles, automated operation and maintenance, automation testing, and game development. Python has obvious advantages, but it also has fatal disadvantages. Python is slow and operating low. Therefore, it is not possible to use Python to implement items that need to emphasize the operation speed!
In my personal experience, it is recommended to learn Python. Python is simpler than Java, with good prospects, high treatment, and many positions. It can be applied to major fields, including: artificial intelligence, data analysis, network crawler, web development, game development, desktop development, automated operation and maintenance, etc. Can't. If it is still not sure, you can see that the link of this video webpage is not bad, and the explanation is more carefully.
