The most significant cause to have Python versus any other language, especially Java, is its unit time per solution which is lower than languages like Java, C++ or C.

But when we are discussing Java, a key factor to note is that it becomes more expressive while continuing to offer the high-performance results in comparison to any other language.

Whenever an aspiring fresh language jumps in, it barely sustains in its toddler years because it focuses chiefly on the expressiveness rather than overall robust performance.

Yes, we are in the era of languages like Python and Kotlin that are getting popular by the day.  But we cannot deny the facts that support the sustained and consistent performance of Java that makes it the most vibrant programming language for over 20 years.

Let’s first discuss why there lies a common perception that it’s more fun to be a Python programmer than a Java one: 

The answer is simple: because Python is a really simple language which is why it has succeeded in garnering more attention among coders who tend to have more fun working with it.

The basic motto behind its design is to express and to promote the readability of code. It allows a simple expression of concepts in very few lines of coding, unlike Java. And it can run almost anywhere.

More ever it is a programming language having win-win characteristics concerned with memory management. 

Python supports automatic memory management and can function properly in both imperative and object-oriented paradigms equally. Supported by these characteristics, Python is doing excellent and scaling up rapidly to match the demands of complex programs.

Python's unit time per solution is lower than any other language such as Java, C++ or C because it is really fast to write and relatively easy to use leading Python to be used rapidly to build projects at scale.

As a strong server-side scripting language, it is one of the fastest-growing open-source programming languages and is mostly used in industries such as:


The largest stock exchange applications in the world.

Air traffic control

cell phones

High-end publication websites

Shipbuilding

Animation movies, among others


Moreover, Python was built so that the programmer could focus on the business rules for the application instead of the commands they should use. 

In short, Python can win over Java when there is an immediate demand to get up and start running quickly with a new project.

Despite these outstanding benefits of Python, we feel coders and programmers should go with Java in terms of overall performance and an agile expressiveness. We can actualize the ease of use of Python and can adopt the same in our future projects but Java does few things better than Python and other programming languages such as those listed below:


Pure object-oriented programming language

JVM makes it easy to create cross-platform compatibility

Supports multi-threading (but Python is effectively single-threaded)

Building large traditional applications

Faster than other languages as it is a compiled language

More popular for mobile and web applications

Used by 90% of the Fortune 500! In fact, tech giants such as Google, Pinterest, Airbnb, Netflix, and LinkedIn are just some of the companies that still use Java one way or another.

Database access layers of Python are weaker than Java’s JDBC. This is why it is rarely used in enterprises.


Let’s not forget – The Impact of the GraalVM in the future of Java


At the outset, we know that today's market is dominated by cloud-native application development, IoT, open-source, Function-as-a-Service (FaaS), reactive and 12-factor. To match all these new tactics of programming, Java is the all-suite presented by the Java development team of Oracle Labs that took seven years to develop the GraalVM.


GraalVM provides a framework that supports Java and other JVM-based languages including Python, C/C++, JavaScript, Ruby, R, and other LLVM-based languages. It includes many deployment outlines like Oracle Database, Node.js and OpenJDK to run codes.


GraalVM offers different kinds of native binary compilation. It is crafted as the best-of-the-breed Java libraries and functions on high standards that result in higher levels of productivity, proficiency and efficiency for Java and all other JVM-based languages.


So, what’s the verdict?


It cannot be denied that Python is an exceptionally popular language, in demand in most industries. However, performance is a factor where Java has a substantial advantage over Python. For instance, Java’s just-in-time compilation has an advantage over the interpreted performance of Python.


And although both Java and Python are mostly used in companies, departments, and commonly famous among their developers, Java finds more use in contemporary times because of its widely used API’s.


Java application code- and Java programming jobs- aren’t going away any time soon. The difference in performance between Java and Python becomes significantly apparent in cases, such as a simple binary tree program that runs ten times faster in Java than in Python. What’s more, with the continued boom in Android and enterprise-level applications, Java is far from being imperiled by the onslaught of newer languages flooding the tech space every now and then. Java is certainly here to stay. For many more years to come.
