Differences Between Java Performance vs Python
Before comparing and analyzing the performance of both Java performance vs Python we must know the basics of Java performance and Python.
Java:-
It is platform independent (because of JVM) and a compiled language written in C++ (JVM provided by Oracle is also known as Hotspot). Oracle Java compiler is written in Java itself. Its execution model is more like machine-centered rather than purely interpreted language. Java is more than a language and libraries, it also provides a virtual machine. So it can be called an ecosystem.
It is dynamically linked allowing new code to be downloaded and run but not dynamically typed.
Python:-
It is an interpreted language and its reference implementation is written in C known as C Python and this is also available on any platform which makes it a portable option for general development purpose.
Implementations of Python are also available with different languages like C# and it offers a close integration with .NET runtime popularly known as Iron Python. There are many others like PyPy, Jython etc.
It also supports procedural programming, modular programming and some shots of functional programming.
This is some basic things about Java vs Python. In this sections, a lot of curiosity may arise for beginners about interpreted and compiled language, C Python, IronPython and a few other terms used. So you may always explode out of these things from the web.

Key Differences Between Java Performance vs Python
Below is the list of points describe the Difference between Java Performance and Python
- Following are the key difference between Java performance and Python which we have to analyze and asses before taking a decision for which language we should go.
- Java is a compiled language whereas Python is an interpreted language and due to this execution speed becomes a factor.
- Due to its simplicity codes are written in Python is usually 3-5 times shorter in length than its counterpart which is a big factor when the performance comes into the picture as the developer has to write fewer codes so development becomes easy and less time-consuming.
- Portability is also an important aspect when the performance comes into the picture. As we have already learned that both Java performance vs Python languages are portable but due to the popularity of Java, it wins.
- Database accessibility is an import factor while analyzing performance. As we also know that data access part of python is weaker than Java’s JDBC so building an enterprise application where database access is more often, python is less productive.
Comparison Table Between Java Performance vs Python
Following is the Comparison Table Between Java Performance vs Python
| The basis of Comparison between Java Performance vs Python | JAVA |
PYTHON |
| Language |
Compiled. A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not step-by-step executors of source code, where no pre-runtime translation takes place.
|
Interpreted. An interpreted language is a type of programming language for which most of its implementations execute instructions directly and freely, without previously compiling a program into machine language instructions
|
|
Declaration Type |
Statically. It means that one has to declare the type while writing code. Ex: String str=”abc”;int i=0;
|
Dynamically It means that there is no need to declare the type of the variable while writing code, it is assumed at runtime. This is also called as Duck Typing. Ex: str=”abc” i=0
|
| Syntax |
Syntactically in java, we have to write a lot. Ex: Semicolon is must to end a line. String str = “this is in Java”; For commenting out a line we can use // or /**/ To define a method or blocks with multiple lines it is necessary to put the lines inside curly brackets. |
In python, it is way easier to write code than Java because of syntax.
Ex: Semicolon is not required. str =”this is in python” For commenting outline in python, we can use #Python mandates indentation even for blocks with multiple lines. |
|
Verbosity/Simplicity
|
Lines of code written in Java is usually lengthier than Python Ex: Class A{public static void main(String args[]) { System.out.print ln(“this is in java”)}} |
Due to simple syntax code is written in python are usually 3-5 times shorter than its counterpart.
Ex: print(“this is in python”) |
| Portability | As we all know Java is a portable language so do its counterpart but due to its popularity, it wins the race when portability is a factor. | Python too is a portable language as Java is but it is somehow less popular in comparison to its counterpart. |
|
Database Access |
Java has its own database access module, JDBC which is very powerful and with JDBC it is possible to connect to almost every database available. | Python’s database access layer is weaker than Java’s JDBC so it is less used in enterprise applications where critical database application exists. |
| Speed |
|
|
| Version | Upgrading to a new version in Java is easy. Like if some code in Java version 7 and like to upgrade it to Java version 8, one can do so without any hassle. | But it Python it’s really a challenging task to switch from Python 2.x to Python 3.x. Both versions are maintained in parallel |
Conclusion – Java Performance vs Python
Java performance vs Python is both in it for a long haul. Java performance and Python are both suited for development but the choice is dependent on many aspects which once should analyze it before choosing. Under the above circumstances, we can say that both Java performance vs Python languages has their own benefits. Opting for Java or Python is based upon the choice of the developer and the business requirement.
