3. Overview
A Brief Introduction
Python vs Java differences is also an overwhelming
comparison for the students. There are hundreds of
blogs over the internet that are showcasing the
comparison between Python and Java. But no one is
giving a solid reason for “is python or java easier.” We all
know that nowadays Python is competing with almost
every programming languageJava is one of the best
programming languages to create desktop applications.
But it is also used in the field of data science. Therefore
both of these programming languages are competing
with each other in various industries. l

4. Java
Java is one of the oldest and most powerful
programming languages in the world. It is a general-
purpose and statically typed language. It means that
anyone can use it. There is not a specific purpose to use
this programming language. Java was first released in
1995 by Sun Microsystem. Oracle Corporation acquired
Sun Microsystem. The initial version of Java was to be
built for portable devices and set-top boxes. Nowadays,
you can download Java from the official site of
Oracle.Java is also an object-oriented programming
language. That makes it one of the easy to use
programming languages. Java is also a portable
programming language and works on WORA (write
once run anywhere). It means you can write the Java
Program on a specific machine and use it on any
platform.

5. Python
Python is the most popular programming language of
the 21st century. It is one of the simplest programming
languages in the world. That’s why it is becoming the
first choice for beginners. Python was invented in the
late 1980s by Guido van Rossum in the Netherlands. The
implementation of Python was started in December
1989. But the first version of Python (0.9.0) came into
existence in February 1999. Python is also a general-
purpose programming language. Most of the
programmers said that it was derived from ABC
programming language.Python is an open-source
programming language. It means that there is not any
specific owner of Python in the world. An open-source
community maintained it. Python is a high-level object-
oriented programming language. It is also offering
dynamic binding options to the programmers.Th

BASED ON CRUCIAL POINTS

7. PYTHON VS JAVA SPEED
When we talk about the speed, Python is not as fast as Java. Because
Python offers one of the slowest architectures for the programmers, which
makes it a long time process to convert the code into machine language.
Therefore it became one of the slowest programming languages to convert
the code into the machine language. It converts the source code into
machine language at the run time.
On the other hand, Java architecture is much more reliable and faster as
compared with Python. In Java, the source code is easily converted into the
machine language in the compilation time. It saves a lot of time and
memory on the computer and provides faster code execution.

8. PYTHON VS JAVA EASE OF
LEARNING
Python is the easiest programming language for beginners. It is a
dynamically typed programming language. Therefore the syntax of Python
is similar to pseudocode or plain english. You need not remember a well-
structured syntax for Python. Python community is available in many
countries around the world. And there are also many groups for the Python
developers.
On the other hand, Java is not an easy programming language for
beginners. It has one of the most complex syntaxes i.e., quite hard to
understand for the beginners. But if you know the C++ programming
language, then you will find Java quite more straightforward for you.

9. PYTHON VS JAVA GAME
DEVELOPMENT
When we talk about game development with Java or Python. Then both of
these programmings are not the best option to create high-end PC games.
But we can create some of the low-end games with the help of Java and
Python. Apart from that, these languages are also helpful in graphics
software. Python offers some of the most powerful engines or frameworks to
create games. Some of the most popular are Cocos, Panda3d, and Pygame.
On the other hand, in Java, you can use the JMonkeyEngine for game
development. It is one of the best and most powerful open source game
development engines. You can create some excellent games with the help
of this engine. Apart from that, you can also create your own engine with the
help of OpenGL in Java.

10. PYTHON VS JAVA WEB
DEVELOPMENT
Python offers us the Django and Flask framework for web development.
Flask offers us the basic functionality like routing request. While Django is
more potent than Flask, it allows you to build a robust backend with
efficiency and security. Apart from that, Django also has the ORM layer,
which makes it the best framework to deal with databases and perform
various data operations.
On the other hand, Java offers the Spring framework that is one of the well
known Java backend frameworks. It provides a massive ecosystem to the
developers. Spring is used by some of the well-known corporations i.e., GE
and dell. You can build powerful web applications with the help of this
framework.

11. PYTHON VS JAVA MACHINE
LEARNING
Python is one of the best options for machine learning. As it allows you to
perform various options without the need for complex programming. Most
of the AI and machine learning developers are using Python. It offers various
libraries and packages for AI and machine learning. It also offers huge
ecosystems to develop AI and machine learning applications.
On the other hand, Java is also one of the best options for machine learning.
The reason is you can easily debug the Python program and use it. The Java
programs are widely used to create large-scale and enterprise-level
applications. Java is offering various libraries for machine learning and AI.
You need not generate the code from scratch to use Java for machine
learning.

12. WHITESPACE
In most of the comparisons the whitespace may not be the point to
compare. But whitespace plays a crucial role in Python. In python tabs are
used for nesting and colon is used to start the loop and conditional blocks.
Python code is concise as compared to other programming languages.
Sometimes it becomes overwhelming for the programmers to do coding in
Python.
On the other hand, there is no role of whitespace in Java. Java completely
ignores whitespace. It uses the semicolons, parentheses, and braces in its
syntax.

13. PYTHON VS
JAVA PERFORMANCE
When we talk about the performance of both of these programming
languages, then both of them are compiled to bytecode and run in virtual
machines. Both of these programming languages are cross-platform. In
Python the code compiles at runtime.
On the other hand, Java compiles the code in advance. Then distributes the
code in the bytecode. That’s why Java is offering better performance over
Python. The JVM uses the JIT compilation for all the programs. It means that
the entire program is compiled in advance. The main version of Python
doesn’t have the capability for advanced compilation, but some new
variants of Python are capable of doing so, such as PyPy.

14. PYTHON VS JAVA
ARCHITECTURE
In Python architecture, the code converts the bytecode. And then, the
bytecode converts into machine code. The machine code stored in another
folder. The machine code is not translated at runtime. It means that the
bytecode is sent across the Python Virtual Machine. PVM is responsible for
running the Python code across various devices.
Java architecture is considered one of the most exquisite architectures of
any programming language. Java offers a runtime environment to operate
the code. In Java, the Java bytecode converts into machine language. The
machine language code is compiled at the time of execution.

17. PYTHON VS JAVA DATA
SCIENCE
Python is one of the most popular programming languages for data science.
It is quite helpful to perform various operations in data science. Python is
quite helpful in collecting data from multiple data sources. It is quite easy to
organize the raw data in the data warehouses with the help of Python. Apart
from that, Python is also helpful to store structured and unstructured data in
Big data operation.
On the other hand, Java is not that popular in the field of data science. But
few of the companies are using Java in the big data technologies because of
its architecture and features. Apart from that Java is also used to build the
custom data warehouses. That’s why the demand for Java developers is
increasing at a rapid pace.

18. Conclusion
Both Python and Java are powerful programming languages. Therefore it is
hard to pick anyone. But let me help you to choose the best one between
Python vs Java for the future. If you want to make a career in machine learning
and artificial intelligence, then Python is the better option for you. On the
other hand, if you’re going to make a career in web development, then you
should go with Java. For the data science field, you can pick either one.
