With the rapid development of the Internet, more and more people choose to join the IT industry. In recent years, the programming language ecosystem is also blooming...
So, for those who are new to the industry, which programming language should they choose to learn better? Is it the Java that has always come out on top, or the late-comer Python, or the big data and artificial intelligence that have been very popular in the past two years?
Before making a choice, we must first have a conceptual understanding, that is, Java, Python, and the so-called big data and artificial intelligence are not the same kinds. Java and Python are computer programming languages. Big data and artificial intelligence are more like the development direction of the Internet. In a sense, they are the relationship between inclusion and inclusion.
After clarifying this concept, let's talk about these two programming languages:
One, Java
As the world's largest development language, Java has a history of more than 20 years and is used by millions of developers all over the world. For a long time, Java has existed as the master of the programming language community.
What are the advantages of Java:
1. As a pure object-oriented language, Java can directly reflect and display the objects in the world, and realizes the object-oriented theory very well, allowing programmers to perform complex programming in an elegant way of thinking.
2. Cross-platform compatibility. As an interpreted language, java can be compiled at one time and run everywhere across platforms. You only need to install the corresponding jvm on the operating platform.
3. By providing a built-in class library, Java can simplify the programming work of developers, thereby shortening the development time of the project. At the same time, Java also provides support for web application development. For example, Applet, servlet and jsp can be used to develop web applications; socket and rmi can be used to develop class libraries for distributed applications.
4. Java has better security and robustness. In order to enhance the security of the program, the java language provides a security mechanism (data boundary detection and bytecode verification, etc.) that can prevent malicious code attacks. Therefore, the java language is often used in the network environment.
5. On the basis of absorbing the various advantages of the C++ language, Java also abandons the concepts of multiple inheritance and pointers that are difficult to understand in the C++ language.
From the perspective of development, the Java language can be widely used in web development, big data development, Android development, server development, and so on.
From the perspective of market demand,
At present, the salary of Java talents is generally very high, and the salary of the relatively good ones can reach 30 K within one to two years of graduation.
Two, Python
Python is an object-oriented, interpreted computer program design language. Python has a rich and powerful library. It is often called a glue language, which can easily combine various modules made in other languages.
1. Simple and easy to understand; Python's positioning is "elegant", "clear", and "simple", so relatively speaking, Python is more suitable for non-computer professionals. Using Python hardly requires any programming language foundation, especially knowledge of data types, just take it and use it. But Java is different. You have to understand the difference in data types before you can start programming.
2. The development efficiency is high. Python has a very powerful third-party library. Basically, you want to achieve any function through the computer. There are corresponding modules in the official Python library to support it. After downloading and calling directly, you can do it on the basis of the basic library. Development greatly reduces the development cycle and avoids re-creating wheels.
3. Compatibility, specifically, portability: Due to its open-source nature, Python has been ported to many platforms (it has been modified so that it can work on different platforms).
Scalability-If you need a piece of your key code to run faster or want certain algorithms not to be made public, you can write part of your program in C or C++, and then use them in your Python program.
Embeddability-You can embed Python into your C/C++ program to provide scripting capabilities to users of your program.
In terms of development direction, Python's main application areas include cloud computing, WEB development, scientific computing, artificial intelligence..., and more applications include full-stack development, data analysis, operation and maintenance development, etc.
The starting salary of Python engineers is mostly 30K, and the starting salary of engineers over 3 years is mostly more than 40K. Most of the people who learn python are not from majors, and many universities have not started this major, so there is a big talent gap in the market.
On the whole, both Java and Python are technologies that are urgently needed and in short supply in our era, and there is a great demand in the market. In the specific choice, beginners can make specific considerations according to their own situation. In specific directions, big data, cloud computing, and artificial intelligence are better choices.
