Java vs Python: Spot the Difference

Java vs Python

Java vs Python

Java

Java is one of the high-level, object-oriented programming languages which has a special feature called WORA ( Write once, run anywhere) which makes this language one of the favorite languages in the programming community. Java is both interpreted and compiled language which is done by using JVM ie Java virtual machine.

Java was originally developed by James Gosling and was released in 1995. From then, there were many updates in the language, as of October 2021, Java 17 is the latest version. Oracle released the last zero cost public update for the legacy version Java 8 which means that it is made available publicly at no cost. Anyone who wants to use java can download it from the official website.

Python

Python is an interpreted, high-level programming language. It supports multiple programming paradigms such as structural, procedural, object-oriented, and functional programming. 

Python was originally developed by Guido van Rossum and was first released in the year 1991 as Python 0.9.0. Python 3.0 is the stable version of python and it was released in 2008.

Java vs Python

Java and Python are high-level languages, object-oriented, and interpreted, but there are slight differences that will be discussed in this blog. Both languages are considered to be one of the trending programming languages with rich community support all over the world.

Differences

Beginner friendly :

Python’s syntax is much easier and simpler to write or to understand compared to Java’s syntax. If you are a complete beginner and want to start with a programming language, you should definitely try learning python.

Example:

Java Code

class demo {
  public static void main(String args[]) {
    System.out.print("Hello World, Welcome to TUF");
  }
}

Output: Hello World, Welcome to TUF

Python Code

print("Hello World, Welcome to TUF")

Output: Hello World, Welcome to TUF

Frameworks : 

Java frameworks are classified into various types and programmers have multiple options to choose among them like spring boot, hibernate, etc.. . But coming to python, it has only two options: Django and flask.

Speed : 

The speed of the programming languages matters a lot when the code is being written for a larger audience. If the programming language is faster it means that it is scalable i.e., multiple persons can access the web page simultaneously. Java provides a virtual machine which is known as Java virtual machine (JVM) which makes it a compiled language by converting the java code to byte code and this increases the speed compared to python. 

Dynamic language and static language: 

Python is one of the dynamically typed languages which means that we need not declare the data type when we create any variables but java is a static language in which every data type has to be mentioned when they are declared.

Example:

Python: 

number=10  // Integer
name=”Striver” //String

Java: 

Int number=10; //Integer
String name=”Striver”; //String

Adaptability to new technologies:

Python has a huge support of libraries like Tensorflow, Pytorch, matplotlib, NumPy, pandas, Keras, etc.. to use machine learning algorithms where java has tremendous support from its libraries to work on technologies like blockchain which is used in cryptocurrency.

Advantages of Java

  1. Platform independent: As Java supports the concept of JVM, the code can be run on various systems if we have the byte code and java installed on that particular machine.
  2. Multi threading: Java supports a concept called multi-threading which is one of the powerful mechanisms when there are multiple programmers working on the same machine. 
  3. Secured: Java does not allow the programmer to directly contact the OS as C or C++ does. When programmers can’t access the resources directly from the OS, the chances of injecting malicious code into the OS will be very less which makes Java secure.

Disadvantages of Java :

  1. Speed: As the java code has to be interpreted first, this may take some time compared to compiler-based languages like C and C++.
  2. Lines of code and complex syntax: The number of lines that we write in java is much higher than in languages than in python which makes it hard to remember all the syntax.

Advantages of Python : 

  1. Simple: The syntax of the Python language is the easiest of all the programming languages that are present in the community and this is the perfect reason to choose it as the first programming language to learn for beginners.
  2. Dynamically typed: When we create any variable or create any memory, we need not mention it in the code, the interpreter will take care automatically.

Disadvantages of Python : 

  1. Absence of Pointers: Python does not support the concept of pointers which is helpful to understand memory management, if someone wants to dig deep down into it while learning, python may not be a better choice to learn about memory management.

Applications of Java : 

  1. Web development
  2. Desktop GUI
  3. Mobile Applications
  4. Distributed applications

Applications of Python : 

  1. Web development
  2. Data Science
  3. Machine learning
  4. Web Scraping

Conclusion: 

Like a coin has two sides, both languages work completely well in their respective areas. It completely depends on the requirements of the client and the interest of the programmer to choose whether python or java.
