In software development, choosing the right programming language can make or break your next big project. There is an ongoing debate about which is better – Java or Python? Both have been around for quite a while but Python has been gaining in popularity because of its vast set of libraries and ease of use.

Python is more approachable for the aspiring developers, whereas, Java has a steep learning curve.
Let’s discuss the differences between the two and explore the various advantages of using Python over Java.

What is Java?

Java Is a high-level, class-based, object-oriented programming language that was developed by Sun Microsystems and introduced on May 23, 1995. It is a widely popular framework used for designing millions of web applications and is a network-centric coding language that can be used as a platform by itself. Java is famous for being fast, secure, reliable, and can be used to design a variety of mobile apps and enterprise software, right from server-side technologies to big data applications. Java can be used to build localized software and is often referred to as WORA which stands for Write Once and Run Anywhere. It is perfect for designing decentralized cloud-based apps and can be integrated with advanced technologies like virtual reality and machine learning.

When you code with Java, the code gets automatically converted to machine-readable code and is compiled, which makes it one of the faster choices.  Java is helpful for building web applications, microservices, and enterprise-level applications for a variety of industries such as healthcare, finance, education, Fintech, governments, etc. Big companies like NASA, Google, and Facebook use Java these days too.

What is Python?

Python is an object-oriented, interpreted, general-purpose, and high-level programming language used to build dynamic enterprise-level apps and web services. It emphasizes the use of built-in data structures and combines dynamic binding with dynamic typing. Python is ideal for rapid application development, is simple to use, and is extremely easy to learn.

Its syntax is not complicated and the framework supports various packages and modules, thus encouraging program modularity and code reuse. Many standard libraries in Python are available in binary format as well as in the source code, and they can be freely distributed at no additional cost across all major platforms.

Python can be used for everything from software testing, machine learning, automation, data science, and web development. It versatility is one of the many reasons why developers are attracted to it and Python continues to be one of the most in-demand programming languages within the industry. Top companies that use Python nowadays are Industrial Light & Magic, Amazon, Stripe, Quora, Netflix, Google, and Instagram.

History of Java

Java language was initially named ‘OAK’ and designed to manage portable devices and set-top boxes. However, it failed and Sun Microsystems changed from OAK to Java in 1995. It became a popular choice in the web development business and around 2009, Oracle Corporation made an acquisition and took over all of Sun’s software assets, namely – MySQL, Java, and Solaris.

History of Python

Python was first introduced in the late 1980s but actually implemented around December 1989 across projects. Its inventor is Guido van Rossum who is from the Netherlands. Rossum launched the first version of Python (0.9.0) in February 1999, and it was initially derived from the ABC programming language.

Python soon evolved and these days, it is maintained by the core development team that is led by Rossum who still plays a vital role in its advancements.

Python vs Java: Comparison

Feature

Python

Java

Typing

Dynamically typed

Statically typed

Language

Interpreted language

Compiled and interpreted language

Popularity

Very popular according to the communities at Stackoverflow, Octovesrse, and Google Trends Python

Java is less popular than Python nowadays and has fewer users

Application development

Supports building image processing and machine learning applications, scientific & numeric computing, and language development

Can build desktop GUI apps, web apps, enterprise solutions, and embedded systems

Syntax

Syntax rules are flexible and do not require any indentation or the enclosure of braces. Variables are automatically input during runtime and developers don’t need to type them in manually

Syntax rules are very stringent and developers need to type in all the variables

Ease of learning

Java has a complex learning curve and requires dedicated training

Python is easy to learn and use

Code

The length of code for Java programs is greater than Python. For example, a simple “hello world” programs requires the following lines:

public class HelloWorld {

public static void main(String[] args) {

System.out.println(“Hello, World!”);

}

}

Python code is simple and needs only a few short lines. For example:

print(‘Hello, World!’)

Portability

Java applications can be run on any computer or mobile device using the Java virtual machine

Python programs require an interpreter to be installed first on the target machine to execute Python code, thus making it less portable

Database support

Offers stable connectivity

Connectivity is weak

Machine learning libraries

Popular offerings are Mallet, Deeplearning4j, MOA, and Weka

Popular offerings are Pytorch and Tensorflow

Speed

Java is faster than Python

Python is slower than Java

Performance

Java has a just-in-time compiler which is a part of the Java virtual machine. Byte code is generated into native code which is automatically compiled and there is no need for interpretation. Java doesn’t consume much processing power and memory.

Python uses more processing time and memory as variables are not declared by default when writing programs. It increases workloads for the interpreter which makes runtime slower.

 

If you are aiming to boost productivity, Python is a clear winner as it can speed up enterprise application development. Python offers seamless integrations and has many control capabilities that can streamline development workflows. It can model real-world entities and run type-checking at runtime as it is dynamically typed.

Python vs Java: Security

Python and Java are both secure, however, Java has advanced authentication and ccess control functionalities. Java uses bytecode and creates class files with it which is tested by the JVM to check for viruses and malware. Python is easy to debug and keeps the code simple which prevents future risks. It has advanced security measures but falls a bit short behind Java.

Python vs Java: Mobile App Development

Mobile app development is all about speed and Java performs very well when it comes to designing and deploying android mobile apps. Python has a hard time building native apps for mobile devices but can be used to design cross-platform applications using libraries like Kivy. Both Java and Python are preferred by developers in that aspect.

Advantages of Python over Java

Following are the advantages of Python over Java:

  • Python is one of the most incredibly productive frameworks in the industry out there and includes various scientific packages.
