Java Vs Python

Java Vs Python – Difference Between Java and Python

The two programming languages that have taken the Software Industry by storm in today’s world are Java and Python. This is major because of the efficiency, versatility, and automation capability that both these languages have to offer to build highly scalable solutions to real-world problems. Both the languages have their own set of advantages and disadvantages and therefore, let us all dive deep into the world of Java and Python to know more about them.

What is Java?

What Is Java?

Java is a high-level programming language that is multi-platform, object-oriented, and has a network-centric approach. It has a specialty of WORA (Write Once Run Anywhere) approach. Used as a computing platform by the Sun Microsystem, Java was later acquired by Oracle Corporation.

Features of Java

The major features of Java programming are as follows:

  • Object-Oriented: Java, being an Object-Oriented Programming Language, offers a lot of important features like Data Encapsulation, Inheritance, Data Hiding, etc. This makes Java a suitable language to map real-world entities into objects and solve real-life problems.
  • Platform Independent: The compilation of code in Java is not specific to any platform but rather it happens as a platform-independent bytecode. The Java Virtual Machine (JVM) then interprets it.
  • Secure: It helps developers develop secure and tamper-free code using public-key encryption.
  • Multithreaded: It can perform many tasks simultaneously.
  • High Performance: Java provides high performance with Just In Time compilers by compiling bytecode to native machine codes at run time. This enhances the performance of Java.
  • Distributed: Java works really well for a distributed environment. It helps users to create and manage multiple distributed applications simultaneously. Hence the code can be saved on different machines and accessed at the same time. This helps in the creation of large projects (Using Remote Method Invocation this can be achieved).
  • Dynamic: It is designed to change according to the way the environment is modified.
  • Low lying constructs like pointers are not taken care of by Java. Pointers are complicated and unsafe to use by programmers at the beginning stage. As the focus in Java is around code simplicity – the usage of pointers can make it challenging. Since the memory can be directly accessed the security can be compromised. Thus, a certain level of abstraction is used as pointers are not used in Java.

Disadvantages of using Java

  • The execution of code can become slow because of the Just In Time (JIT) Compiler.
  • The hardware cost increases as there are high memory and processing requirements.
  • Java requires a significant amount of memory space as compared to other languages.

What is Python?

What Is Python?

Python is a high-level programming language that has properties which are mostly inbuilt and supports binding and type casting dynamically which makes it one of the best choices. The various modules and packages allow modularity and code reuse. It is one of the fastest-growing popular languages as the lines of codes are drastically reduced making it readable and simple to use.

Features of Python

The major features of Python programming are as follows:

  • Easy to learn and use: The syntax is pretty simple and hence easily adopted by programmers.
  • Expressive language: Huge chunks of code can be completed using small snippets of code.
  • Cross-Platform Language: Easily works through all the Operating Systems.
  • Free and Open Source: Python is a free and open-source language that can be accessed by anyone from anywhere in the world.
  • Standard Library: The offering of these libraries, for instance, MatPlotLib, Pandas, Request, NumPy, etc., are extensive and make the work of a developer really very easy.
  • Flexible with other languages and tools: Python is a diverse language that can be easily integrated with a lot of tools and frameworks to solve a variety of problems.

Disadvantages of using Java

  • Python is extremely weak in mobile computing. Therefore, it is not widely used in application development.
  • It is an interpreted language and hence slow.
  • Weak in mobile computing and hence it is not used in app development.
  • Python shows errors at run time as it is dynamic. As there is no error generated during compile time, this might result in a loss of time for developers running large chunks of code.
  • There is no commercial support.

Which is better?

Python has a simple and intuitive way of learning. Since the syntax is similar and somewhat as simple as the English Language it is easy for beginners to understand. It is an open-source nature that facilitates a new set of tools that can help improve.

Java on the other hand was developed as a programming language that would be used for general purposes. It was written with the objective of WORA (Write Once Run Anywhere) goal.

To understand which of the two languages should be used for a specific purpose comes to the two basic reasons: Nature and cost of development projects.


Java vs Python: What’s the difference?

Java and Python
Difference Between Java and Python

The difference between Java and Python based on the various factors are as follows:

ParameterJavaPython
CompilationJava is a compiled language. JVM is the core thing used for the same.Python is an interpreted language which means code is scrutinized line by line.
Static/DynamicJava is a static-typed programming language.Python is a dynamic-typed programming language.
String OperationThe scope of string operation in Java is very limited.The scope of string operation in Python is very widespread.
Learning processJava is fairly complicated and it can some time to understand and master the programming language.Python is fairly simple as it is easy to understand and hence recommended for beginners.
Multiple inheritancesJava can implement multiple inheritances partially through the usage of interfaces.Python offers single and multiple inheritances. It is simple to implement this concept easily.
Braces/IndentationJava uses braces to highlight the start/end of any function or class.Python does not use braces but a proper indentation needs to be followed for the code.
SpeedJava is slower than Python.Python is comparatively faster than Java. But in general, it is very slow as compared to other languages like C and C#, etc.
PortabilityAny device capable of running a JVM (Java Virtual Machine) is capable of running a Java Code.Python is comparatively less portable. It needs an interpreter on the local machine to execute the code.
ReadabilityJava needs 10 lines of code from a file to read.Python needs only 2 lines of code to read from a file.
ArchitectureJVM runs codes and converts bytecode into machine-readable language.Python translates into machine-independent byte code.

Conclusion

This is to note that Java and Python are both in-demand languages now. It is to note that both have their individual advantages but Java is more in demand right now. But with the advent of AI and ML – Python has started to gain more traction from the industry. It would be very interesting to note how the industry shapes up but as of now, both these languages are here to stay for a long period of time. This article adds value to your existing knowledge about Java & Python and that will help you make a judicious call about your career prospects as per your interest areas.


Frequently Asked Questions

Which is better: Java or Python?

Both have their individual advantages but Java is a bit more widespread in the industry. But with the advent of AI and ML – Python has started to gain more traction from the industry.

Should I learn Java or Python first?

Python is fairly easy to learn for beginners as the syntax and implementations are not that complexes. Learning Java initially on the other hand will help you visualize and learn some concepts better.

Can Python replace Java?

Java works on the concept of Write Once Use Anywhere(WORA) whereas python needs a python compiler to write and run the code. In the coming days, the industry demand for Python may exceed that of Java. This would not mean that Java will run out of business ( both can co-exist).

Is Python enough to get a job?

Yes, python would be enough to get a job. But most jobs require a set of skills. For example: if your Python codes are using a MYSQL database – then in that case having knowledge of both aspects helps the developer land a better job.

Which pays more Java or Python?

With the demand and changing industry trend: Python developers are getting paid a bit more than Java developers.

Can I learn Python on my own?

Absolutely, yes. A person can easily learn Python on their own but that might stretch the time for you to grasp each concept. Learning via online free resources and books would be a better approach.
