Python vs Java – Demystifying Crux of Programming for App Development

Programming has its fair share of contributions made to technology which is growing more advanced with each passing day, empowering the business world. 

Often hailed as a pinnacle of technology, a programming language entails a group of commands and codes for designing a software program. Technically speaking, the viability of programming languages in software development can’t be underestimated,  thanks to their virtue for developers. However, choosing the right programming language is a mind-numbing task, even for expert programmers. 

In this context, choosing between Java and Python could also be a difficult task, given both programming languages are platform-independent and supported by a large community of enterprise application developers around the world. 

When it comes to building enterprise software solutions, choosing between Python and Java requires a deep understanding of which language syntax can fulfill your project requirement on every quality parameter. 

Understanding Python and Its Key Characteristics

Developed by Guido van Rossum, Python is defined as an object-oriented, high-level GPL (general purpose programming language) with a design philosophy tied to dynamic semantics and code readability. It is also known as a programming language supporting various programming paradigms (a technique to classify programming languages based on features). It is touted as a beginners’ friendly language due to its graspable concepts. Statista reports that Python secured the top position in the list of most searchable programming languages for the year 2019.

Python is used in diverse areas

Downsides of Python Programming Language

Poor Memory Efficiency

Python is problematic because of its poor memory efficiency. In other words, it depends on too much memory consumption due to the flexibility of data type, causing problems when you want to optimize memory-intensive tasks while developing an application.

Poor Speed Of Execution

Slow speed is one of the biggest disadvantages of Python. Since it executes code one line at a time, it compromises the speed of execution. To say the least, in an enterprise application development where speed matters, employing Python for coding is an ideal recommendation.

Database Access

Python features a limited and primitive database access layer. Unlike technologies like Open Database Connectivity, Python has an underdeveloped database access layer. It simply means that the programming language is not viable for deployment to ensure hassle-free interaction of rather complex legacy data.  

Runtime Errors

Python faces several design-related issues and it requires more testing. Python’s data types of variables are volatile. Python encounters runtime errors as it is a dynamically typed language. 

Not Suitable For Front-End Programming

Python is not considered suitable for front-end programming as it is mostly heavy on memory consumption which is suitable for back-end programming.

Downsides of Java Programming Language

Average Performance and Slow Speed

Despite all the features and interesting traits, Java’s performance is slower than C/C++. The reason behind the slow performance is that its code has to be deciphered to machine-level code every single time, causing an additional step to execute the program by Java Virtual Machine.

Performance is also sluggish as the Garbage Collection piles pressure on the CPU by taking more time and memory space. This is because garbage collection is an automatic process not controlled by developers and so, it results in the overconsumption of memory space.

Without a Standby Facility for Code

As a developer, you will get excellent storage of code and data in Java but can’t leave them on standby for later use. This simply means that while you can code some programs and run them using available data and code in Java, problems will surface once you find them disappeared and you need to tweak the programs in the future.

Boring and Unworthy GUI

Though Java comes featured with many popular frameworks and builders like Swing toolkit and JavaFX to build good-looking GUI, the problem surfaces when these tools are used to build complex and rich interfaces. A programming language that doesn’t help developers build an attractive interface conclusively gets boring and useless.

Unreadable and Complex Code

Java’s syntax uses long, complex sentences and complicated words to make the program manageable. Therefore, the syntax is not easy to read and can’t be memorized as well. This means the language doesn’t appeal much to the programmers, especially when it comes to coding something long and tricky.

Overconsumption of Memory Space

Garbage Collection is an excellent Java program because of its execution. However, it results in adverse effects on the memory efficiency and CPU performance of the program. This is because Jave heavily relies on enormous memory space and storage. This problem is another reason behind Java becoming a slow programming language.

Java vs Python – The Battle Of Ascendency

In this section, we are discussing a comparative analysis between Java and Python based on different parameters to ensure they are aptly benchmarked, conforming to quality standards, viability, productivity, and efficiency.

1. Comparison Based on Popularity

Both Java and Python have massive popularity worldwide.

In 2018, python rose to fame by outpacing C++. In 2021, GitHub’s Octoverse ranked Java as the world’s 3rd most popular programming language, outpacing both JS and Python.

However, Python bounced back with a surge in popularity by 48.24% compared to Java’s 35.35%, according to Stackoverflow’s Developer Survey in 2021.

Based on popularity, both Java and Python are famous worldwide and give each other tough competition.

2. Comparison Based on Language Syntax

While using Python which is a dynamically typed language, you don’t have to define variable types or input variables during the runtime. In turn, you experience that Python gives you an impression of easy syntax.

Besides, the language doesn’t rely on enclosing braces or indention rules so the code doesn’t seem complex to read and people can write pseudocode.

On the other hand, Java performs in a way that is considered diametrically opposite to Python’s syntax rules.

A programmer has to involve all the variables while ruling out any room for erroneous or anomalous code. If it happens, the program will run into errors. It simply means that Java follows strict syntax rules, considering it is a statically typed language in which developers have to clearly define the variable types to avoid the detection of an anomaly in the code.

Moreover, a block or method with various lines needs to be defined in Java by putting the lines in curly brackets. In Python, indentation for writing blocks with various lines is allowed.

Does that make Java less popular than Python?

Well, it depends on your perspective of you as a developer. If you are okay with following indentation rules, you will lean on Java quite naturally. On the other hand, if you want your program simple without many variables and anomalies in large codebases, Python is good to go for your requirements.

3. Comparison Based on Performance

The performance-based difference between Java and Python is that Java uses a static-typing syntax which allows easy code compilation and is faster compared to the dynamically-typed syntax of Python.

So, Java has less likelihood of risking errors. It targets the platform that expects better performance. Moreover, Java’s Just-in-time (JIT) compiler compiles bytecode into the native machine to call compiled code directly to ensure the speed and efficiency of the Java program.

It, however, doesn’t belie the fact of how difficult and complex Java codes are.

On the other hand, Python is believed to outpace Java based on its highest market share of more than 15.42%, according to the TIOBE index (August 2022).

4. Comparison Based on the Architecture

Java’s runtime environment for code execution pans out a seamless architectural experience for the developers, helping them convert Java bytecode into machine language. Contact a reliable Java software development company to design your app maximizing core Java architecture.

On the other hand, in Python, bytecode is converted into machine code that is stored in a different folder that is not processed at runtime. As a result, the bytecode is received by a Python Virtual Machine in which the actual code is executed.

The above comparison suggests how Java architecture performs more seamlessly than Python.

5. Comparison Based on Code Readability

The coding format of Python is linear and less dispersed as compared to Java.

Python eliminates the need for putting a semicolon at the end of every station and rules out too much practicing of curly braces.

Example of Code Readability of Python

Based on the pictorial comparison above, Python conclusively wins in terms of ‘code readability’ points as compared to Java.

6. Comparison Based on Machine Learning

Since Machine Learning (ML) is a key part of programming languages for driving data-backed insights, let’s discuss how Java and Python perform respectively under this comparison.

Python, as a language of syntactically easy to read and understandable, appears as a comfortable choice to experiment with the algorithm-intense field of machine learning. Besides, the language hosts top libraries for machine learning, including NumPy, SciPy, and Scikit-learn.

On the other hand, Java’s easy debugging and usage features make it an optional choice for enterprise-level programs, though it is considered a bit old for machine learning due to its complex syntax.

Conclusively, we can say that Python has a winning edge over Java for ML.

7. Comparison Based on Gaming Development Functions

Since the PC Game development market is ruled by C++/C# programming languages, both Java and Python, therefore, seem to rule the roost in this comparison. However, Python is better at gaming development due to its low syntax complexities. It is also a user-friendly language for beginners. On the other hand, Java is reputed to be a good data science language supporting Big Data.

On that note, Python seems to be a winner.

8. Comparison Based on Programs

Python is used in various programs if speaking from a language development standpoint.

Python-based programs –

• Software prototyping
• Language development
• Machine learning apps
• Games
• Graphic designing, image processing
• Operating Systems

Java-based programs –

• Desktop GUI apps
• Mobile applications
• Middleware products
• Enterprise solutions
• Embedded Systems

Concluding Statements

While we have jotted down exclusive details based on comparative analysis between Java and Python, we conclude that either programming language can’t be disputed for their respective prominence in diverse application areas. While Java can be said as a language with massive popularity and broad application areas in various fields, it, however, doesn’t belie the fact that it is also disputed for having complex syntax and code readability issues.

On the other hand, Python is said to be a language that is widely used across the enterprise application development industry for organizational purposes and is considered an ideal language for algorithm-intensive ML tasks. Java is relatively faster than Python and preferred choice for enterprise-level programs whereas Python seems to have credibility for language development purposes, including Machine Learning applications.

Conclusively, both programming languages feature their respective essence, though it largely depends on the application areas for which either is demanded. That said, it depends on project size and complexity among other factors to finally decide whether you need Java or Python.

Should I hire a Java or Python development company for my project?

An ideal recommendation for hiring Python software development services is when you want to have a less complex application, given Python is simpler than Java. On the other hand, you can consider hiring a Java application development company for developing an enterprise application, as the language is more succinct than Python.
