chalcedony wholesale gemstone beads for jewelry making 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!
west coast cowgirl jewelry wholesale If you want to learn a computer technology, which prospect of Java and Python is better?
For this problem, people will be caught in the tangles of Java and Python. Today, let's talk about how to choose Java and Python? How to distinguish between the two?
Is this video can help you! Hope to adopt!

how to setup a wholesale account for jewelry supplies Java and Python have become the two most popular programming languages in the market because of their generality, high efficiency and automation capabilities.
java is an object -oriented language, and its grammar is similar to the C/C syntax that many programmers are well known.
java is dynamic links, allowing download and running new code, but not dynamic input.
python is the older of two languages. In 1991, it was first released by the inventor Guidovan Rossum. It is a readable, efficient, and powerful high -level language with automatic management of memory function.
Where is their difference: I summarized 12 points for your reference
. To be honest, the Python virtual machine is not Java strong, Java virtual machine is the core of Java
pythonon The core is that it can easily use the C language function or C library.
. Python is full dynamic
The can modify your own code at runtime, and Java can only be implemented by the change method.
Python variables are dynamic, and the variables of Java are static and need to be declared in advance, so the code prompt function of the Java IDE is better than the Python IDE.
. Design ideas
Python have been produced for decades, and the process is the mainstream decades ago. Therefore, Python has a lot of procedures. Class is later added in Python, and Java is to achieve C without pointers (references for COM components, virtual machines for Java), mainly use objective design methods. Many concepts are OOP concepts.
. The actual Python entry is simple
. You need to learn to work with Python. You need to learn various libraries of Python. The strength of Python lies in the library. Why is Python's library strong? You can use Python, C language, C and other designs, and then provide it for Python.
So no matter the GPU operation, neural network, intelligent algorithm, data analysis, image processing, scientific calculations, a variety of libraries are waiting for you.
and Java do 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, which cannot see the original code.
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 use the source code (Linux), or the source code is simply a package (such as pyexe).
. Python has many virtual machines to implement
, such as Cython, Pyston, Pypy, Jython, etc., suitable for business language, or plug -in language, or domain language, and Java is huge because the virtual machine is huge. It is rarely used for plug -in language, and it is inconvenient to publish.
6. Java is mainly used in areas with strong business logic
. Such as the traditional database transaction in traditional databases such as mall systems, ERP, OA, finance, insurance, etc., through SSH framework transaction code, commercial databases, such as oralce, DB2, SQL Server and other support, strong software engineering concepts, and multi -person development models suitable for software engineers. rnPython主要用于web数据分析，科学计算，金融分析，信号分析，图像算法，数学计算，统计分析，算法建模，服务器运维，自动化操作，快速开发理念强，适合快速开发团队或Personal agile model.
Seven, Java's commercial companies support more
, 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
python is glue. You can use all kinds of unrelated things together. The team of hundreds of people is PK, and the commercial atmosphere is heavy.
. I think that Python is strong, because it can be convenient to call C or C libraries, but software engineering and commercial operations are not as good as Java, which is suitable for fast development.
. About money
If you want to write programs to sell software to use Java, you can use IBM server, Oracle database, on EMC storage, high price, commercial procurement company likes this tall.
If you want to use the program to generate money directly with Python, Python can achieve wide passenger finance, data recovery, stock speculation, speculation of options, frying gold, frying bitcoin, hedging sets, statistical arbitrage, many open source libraries, data Analysis library, the machine learning library can be referred 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.
java and Python are stronger than C#than to support Linux, support OSX, support Unix, and support ARM. The reason why Java and Python are more popular than C is that no pointers are required.
11. For 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, it was developed with Java. Spark was developed with Scala. Scala is based on JVM and Flink is also based on Java. Big data development selected Java. Python is mainly used for big data analysis.
The above answers hope to help you
wholesale jewelry suppliers in canada 1. Python is simpler than Java, low learning costs, and high development efficiency;
2.java operating efficiency is higher than Python, Python is low;
3.java related information, especially Chinese information;
4 The version of the .java version is relatively stable, Python2 and 3 are not compatible that causes a large number of libraries to fail;
5.java development is biased towards software engineering, Python is more suitable for small development;
6.java is biased towards commercial development, Python is suitable for data data Analysis;
7.java is a static type language, Python is a dynamic type language; all variables in
8.java need to be declared first. n9.java can only run after compilation, and Python can run directly;
10. When implementing the same function, the number of keyboards to java to knock is generally much more than python.
antique glass jewelry box wholesale Python is a language with simple sentences. Because many novice programmers like to write very little code, this makes Python be widely used in multiple fields to write scripts, quickly develop applications, and so on.
java is a typical programming language, which means that the variable name must be displayed. In contrast, we have a dynamic type of Python, which does not need to declare variables. Regarding static variables, dynamic variables, you need strong types of language and rigorous compiler to test the code of the prisoner II.
Compared with Java, the grammar of the Python language is simpler and clean, and the syntax of Java is relatively swollen and rigorous.
python and Java prospects and development directions
java development prospects
java language is an object -oriented programming language. The concepts such as pointers, so the Java language has two characteristics of powerful and simple and easy to use.
java language, as a static representative of object -oriented programming language, has greatly realized object -oriented theory, allowing programmers to perform complex programming in an elegant way of thinking. Java language has the characteristics of simplicity, object -oriented, distributed, robust, security, platform independence and portability, multi -thread, dynamicity and other characteristics.
java development direction: web development, big data development, Android development, server development, etc.
java language is currently the highest domestic share programming language. Java is the first programming language of Alibaba Group. The domestic development position recruitment needs are also the majority of Java language. However, because of the popularity of the Java language, a large wave of personnel who trained the Java programming language appeared, which caused the competition of java primary programmers was extremely fierce, provided too much. For developers with more than 3 years of work experience, the influence is relatively mild, and it is still very fragrant.
python development prospects
python is an object -oriented interpretation computer program design language. Python has a rich and powerful library. It is often called glue language and can easily combine various modules produced by other languages.
Python is simple and easy to learn, and it is more suitable for entry without a programming foundation.
python development direction: data analysis, artificial intelligence, web development, testing, operation and maintenance, web security, crawler, etc.
Python's current development trend is very good. With the development of big data and artificial intelligence, the application of Python will be widely popularized. Python is the future of artificial intelligence. Taking into account the flexibility of language, its speed and the machine learning function library will continue to see Python dominant positions in the field of machine learning.
So in the current trend, Python is more promising than Java.
