We all know that the hottest thing now is artificial intelligence 、 big data . The main language used by AI and big data is Java and Python. Let's analyze it today , At present java and python, Which employment prospect is better , Higher pay ？ Which one should I learn ？
Python： Born for Jane
Python Is a high-level programming language with simple syntax . A group called Guido van Rossum The Dutch big man of 1991 It was designed in .Rossum The original intention of designing this language , Just to make the code easier to read , And let programmers compare it with other languages , Can write less code , Yield twice the result with half the effort .
Java： I want to be the eldest
and Jame Gosling stay 1995 It was designed in Java. Java It's a door to Class In units of , High level programming language with high object orientation .Java The original intention of the design is " Write a code once , It can be used anywhere ."Java Can accomplish tasks of any scale , So it is also a common choice for many companies when they are doing business level projects .
1. Compiler language , The compiler generates a .class file , Then from java Virtual machine to run ;
2. Static type language , The data type is determined during compilation , Variables are declared before they are used ;
3. Strong type language , Once a variable is assigned a data type , If you don't cast it, it will always be this type ;
4. Object oriented language , Must be object-oriented programming , Classes to which both variables and functions belong .
Borrow a poem （ excerpts ）：
Beauty is better than ugliness （Python To write beautiful code as the goal ）
Clarity is better than obscurity （ Beautiful code should be clear , Naming specification , The style is similar ）
Simplicity is better than complexity （ Beautiful code should be concise , Don't have complex internal implementations ）
Complexity is better than disorder （ If complexity is inevitable , That code can't have a difficult relationship , Keep the interface simple ）
Flat is better than nested （ Beautiful code should be flat , There can't be too much nesting ）
Spacing is better than compactness （ Beautiful code with proper spacing , Don't expect a line of code to solve the problem ）
Readability is very important （ Beautiful code is readable ）
Even in the name of the practicality of special cases , And don't violate these rules （ These rules are supreme ）
1. Explanatory language , Interpretive language programs do not need to be compiled , The runtime will translate into machine language , but python The program will automatically generate bytecode files during operation .pyc, To improve the python Performance of ;
2. Dynamic type language , Variables need not be declared , It is automatically determined according to the value type when assigning values ;
3. Strong type language , Once a variable is assigned a data type , If you don't cast it, it will always be this type （ Same as java）;
4. Object oriented language , Do not force object-oriented programming , Logic can be handled in separate function modules without having to be placed in classes .
Through rich Web Development framework , Such as Django and TurboGears,Python Can be used to quickly complete the development of a website and Web service . It's typical of bean petals in China 、 Shell net, etc
Operation and maintenance of automation system network , A lot of repetitive work , And need to do a management system 、 The monitoring system 、 Release system, etc .

1. The relationship between salary and working years
In line with the public perception , be engaged in python The average starting salary of fresh graduates is 5K about , And the salary level span is the smallest , Experience 5-10 year , The salary span is the largest , Mainly because , Some of them have been transferred to technical management positions , Those with lower wages may continue to code , Is it a warning to our compatriots …
2. The relationship between salary and educational background （ Specialty , Undergraduate , Graduate student , There is no limit ）
Can you explain the importance of education to a certain extent ？ The salary span of Bachelor degree is relatively large , Because the difference of work experience leads to the difference of salary .
3. The relationship between wages and corporate finance
For this part of knowledge is a blind spot , But it can be seen that the financing company （ Listing is also a way of financing ） It is much higher than the average salary of companies without financing , Is this part a weathervane for future job hunting .
4. The relationship between salary and company size
The bigger the company is , The higher the average salary .
5. The relationship between salary and working hours and educational background
In most cases , no （Ren） money （Chou） Just read more . Whether it's experience 1 In the following 、 Experience 3-5 year 、 Experience 5-10 year 、 Experience is unlimited , The average income of those with master's degree is generally higher than that of those with bachelor's degree , Undergraduate course is higher than junior college .（ There is no discrimination against low education ）
6. Cloud picture of company benefits
Now the company's benefits are " Flexible work , The atmosphere is good , The team , Daniel , technology , Five social insurance and one housing fund " And other labels to attract the attention of job seekers .
1.Python post 、Java post 、C++ post 、PHP post 、C# The average salary for the position
By capturing online job information , It can be seen that python and java Our average salary is higher ,C# The average wage is the lowest .
This also verifies python In recent years, the situation is hot , because AI The hot ,python There is a growing demand for , Conventional java Also quite strong , Higher salary .
2. Salary comparison between different positions with the same work experience 
For different work experiences , The average salary of different programming languages is still quite different .
3. Salary comparison between different positions with the same educational background
Through master 、 Undergraduate 、 junior college 、 There are no four comparisons , The overall salary of a master is higher than that of an undergraduate .
4. Salary comparison of the same position with different educational background information
On the whole , In every profession , The average salary of a master's degree is higher than that of a bachelor's degree , The average salary of a bachelor's degree is higher than that of a junior college .
From the perspective of language itself ,Python Grammatical simplicity , Easy to use , and Java Famous for its unique architecture and fast speed .
Python As a more and more popular language recently , Is the main force of big data and artificial intelligence , It is also widely used in web development . and Java It monopolizes the development of enterprise applications , The salaries of both engineers are considerable .
