Java and Python Fundamentals for Engineers - Part 2

As you have read in Part 1 of the blog, "Basics of Java and Python Programming for Engineering," Java and Python find applications in a variety of domains in today's world, from the simple plotting of graphs to the running of automated systems. 

Developers of both languages have been striving to improve access and efficiency for the past thirty years, and the online developer community gets bigger every day. 

This blog continues from Part 1 and also outlines topics like job opportunities and what solution providers use these languages for.

  • In Python's traditional runtime execution model, your code is translated into byte-code and is run by the Python Virtual Machine (PVM), just like Java. However, the code is compiled automatically and not in an explicit intermediate step.
  • As a consequence of this, the Java program is error-free when you execute it, but you would know any errors in your Python code only when you run it, and not before.

Java vs. Python: Comparison

  1. Speed and Performance: Java is relatively faster in the execution of code compared to Python, especially in programs with hundreds or thousands of lines of code.
  2. Legacy: Adding or modifying legacy systems in Java is more complicated than in Python because of stricter language restrictions and coding etiquette.
  3. Code: For the same operation, Python typically uses lesser lines of code because of the scripting nature of the language.
  4. Cross-Platform Usage: Both languages can be used across different platforms.
  5. Trends: Java is primarily used in embedded systems and enterprise software, and Python finds uses in machine learning and AI (more information in Part 1).
  6. Salary: Due to higher requirements for Python developments - which is relatively new compared to Java - there is greater demand for Python developers and hence, a higher salary for them. However, this trend should not discourage you from learning Java; based on future technological advancements, there could be an increase in demand for Java developers.
  7. Syntax: As mentioned in Part 1, the syntax of Python is the simplest among most programming languages, making it one of the easiest to learn.

Job Opportunities 

Python 

The best Python programmers are hired by companies looking for data scientists and machine learning engineers. Note that data scientists also need to know the basics of statistics and math. You can also perform data analysis on languages like R and MATLAB, but Python is by far the most popular choice. 

Software engineers also use Python to some extent. In fact, you can become a professional Python developer whose job is to improve the framework of the language and the libraries for various purposes. 

Java 

Java programmers qualify for more generic profiles like enterprise architects, service managers, software engineers, or application specialists. You start by performing specific tasks, and, with more experience, your profile would require you to provide consulting services and create complete solutions for clients. 

Career Path

Within most organizations, the higher up the ladder you go, the more managerial work your role demands. The same goes for the roles of a Python or Java developer as well. 

You enter the firm as a junior software developer or junior data scientist, get promoted to a senior engineer, and then move on to leadership positions. Managerial roles are typically that of development managers, project managers, or, more recently, Agile managers. 

Although the coding component of your job profile reduces, you should still be up-to-date with programming to run your team of developers efficiently, perform quality checks, and to present the work to the clients. Within IT firms or software companies, you can rise to the CXO level.

In contrast, in manufacturing sectors or other industries, your top position would usually be along the lines of IT Head, Chief Software Engineer (or Architect), or Regional Manager. 

Solution Providers

In India, the leading solution providers are IT services companies like TCS, Wipro, IBM, and Accenture. Clients from other sectors (like manufacturing) would approach these companies to create a customized product or to develop applications that run on their existing Java or Python framework. 

For example, TCS has created a product called "BaNCS," which is a core banking software suite for retail banks to use. It handles operations related to payments, wealth management, forex, and insurance, and is written in Java. IBM uses Python extensively for automation-related purposes, like creating chatbots for clients to use for their websites. The tech giant Google uses Python for internal data science applications.

Due to its more generic nature, Java is more commonly used by companies than Python. Microsoft, Dell, HP, Facebook, and Twitter are some of the leading companies that create products written in Java. Some of these companies' own framework is entirely designed in Java, like Intel's embedded systems. 

The recent usage of Python has shot up. In the financial sector, Goldman Sachs, JP Morgan, and PayPal use Python in their applications, typically the back-end systems, to store and bifurcate data. Netflix, Spotify, and Pinterest are some entertainment firms that use Python for analytics and artificial intelligence to curate content and suggest recommendations to viewers. The space agency, NASA, also uses Python.

Conclusion 

The Java and Python fundamentals for engineers explained in this article should give you a clear picture if you planned to take up professional courses in either language. Both languages are indispensable in today's world, and the developer community will only grow larger in the coming years. The best option would be to learn the basics of both languages and then choose to specialize in one. 

There is no secret to becoming experts in Java or Python; all you need to do is start coding and practice and improvise continuously. Most programmers today learn these languages through online courses, assignments, and projects. Unlike theoretical courses, programming can be acquired only through practical experience and application in real-life scenarios.
