Python vs Java: Difference in performance, salaries and more

Python and Java are both strong object-oriented languages. They both are used to create a lot of applications. They don’t have many similarities but they do have some key differences. Python has gained popularity since its release while Java has remained at its position. If you are looking to choose one of them for your career then this article is for you. There has always been a rivalry between Java vs Python about which one is better. 

Let’s have a look at their differences in detail.

Python

Released in 1991 by Guido van Rossum, Python is an easily readable, simple, and user-friendly language. It is an object-oriented and explained programming language with a strong definition. The code in Python gets assembled and carried out at the same time. Python was released to fill the gap between C and the shell.

It has a very easy syntax.

Python has built-in, high-level data construction. Using this, we can do really strong typing and binding. It does not have an assembling period. This helps the process go faster. To add to that, it has a simple syntax that helps cut the cost of maintenance.

Since in Python the code is assembled and carried out at the run time it is really important to check the code thoroughly for any debugs or errors so it doesn’t affect the performance of the application.

Java

Java is an object-oriented programming language. It is used in many mobile applications. Java was developed as a Write Once Run Anywhere language so it has reusable code and is also perfect to perform on any platform, with the help of Java Virtual Machine(JVM). JVM helps cut the development period and elongates the life of the application.

Java is commonly used in cell phones, laptops, and supercomputers. It can perform multiple tasks at once. It is a platform-independent program so you can create the code on one platform and carry it out to another easily.

Java does not have a strict syntax which may seem like an advantage but is not. Since it doesn’t have a strong syntax it is easy for your application to have a lot of errors.

Python vs Java

We’ve learned a lot about Java and Python in this article, let’s have a look at which is better.

The comparison between these two programming languages simply falls on the task you’re doing. 

If you’re looking for a good career start in programming, Java is for you.

Performance- If we talk about the performance comparison, Java is generally much faster since it is a compiled language. Remember that languages don’t have speed, they only have semantics, therefore, there can’t be an actual comparison. Writing codes in Java is much faster because it’s a compiled language whereas Python can take two-three lines to write the same code.

Popularity-It has been noticed that Java and Python have always been in a tussle when it comes to their popularity.

Java and Python are both fairly popular but Python has shortcodes which makes it easier for developers to read it and make required changes, therefore Python takes the flag in popularity. 

Code-As we’ve already discussed above, Python has shorter and easier codes since it uses active types. While Java, on the other hand, uses static types so the code in Java has to be declared per variable, which increases the length of the code.

Syntax-Syntax is the rule that is necessary to follow while writing code in any programming language. Since the code in Python is compiled and carried out at the run time, you don’t need to change the variable type as the explainer will check them at the run time. Which effectively makes it a beginner-friendly language. However, in Java, the variables are checked during the compile time hence all data needs to be declared in the code. In Java, every code must end with a semicolon, which makes it somewhat harder than Python to learn, especially for beginners.

Salary and Jobs

It doesn’t matter if you choose the language based on its popularity since both of them are almost at the same level when it comes to popularity.

In India, the average salary for a Java developer is ₹4,55,000 per annum(Source: Glassdoor) and for a Python developer, it is ₹4,46,000 per annum(Source: Glassdoor). So if you become flawless in Java or Python, you can easily start your career as a developer. 

One thing to keep in mind while choosing one of them is what your task requires. 

Some popular apps that are built using Java are Netflix, Spotify, and Uber.

Some popular apps that are built using Python are Facebook, Instagram, Google, and Pinterest.
