Java: Overview

Java is one of the robust and widely used programming languages in the world. It is also known as dynamically typed general-purpose language. Java runs on almost 3 billion devices worldwide. It is the most popular object-oriented programming language. It was developed in the year 1995 by Sun Microsystem. Later Sun Microsystems acquired by Netscape.

Now Java is the product of Netscape. Java is compatible with every operating system, i.e., Mac OS, Windows, and Linux. It uses the JVM to run the program on any platform. Java has three categories, i.e., EE, ME, and SE. It is based on the simple phenomena of writing once and running everywhere. Java offers lots of features to the users, likewise secure, simple, interpreted, multithreaded, dynamic, robust, and many more. 

Python : Overview

Python is one of the most powerful object-oriented programming languages in the world. It is all in one programming language because it offers a variety of functionality to its users. It was developed in the year 1985 by Guido Van Rossum at a research institute in the Netherlands. But the first-ever release of Python was in the year 1990.

In the early days of Python, it wasn’t a popular language, likewise Java and other programming languages.  But when big data came into existence, Python got a boom and became one of the world’s highly demanding programming languages. Most programmers love Python because it is highly readable and easy to understand.

Python uses simple English keywords to write the program, whereas other programming languages use punctuation to write the program. Likewise, Java, Python is also offering some brilliant features to their users. The features are easy to learn and read, highly interactive, portable, scalable, and many more. 

Syntax class A {
 public static void main(String args[]){
     System.out.println(“Hello World”);
Hello World in Python:
print “hello world”;

Java, programs are based on strict syntax, which means that you have to write a Java program on your own. In other words, you have to declare whether the variable is int, float, double, etc. Then you need to follow some strict syntax rules on Java.

It is a statically typed programming language. It means that you need to declare the types of your variables before using them in the program. If you don’t do that, the program will not run anyhow. For most of the developer, statically typed language is the best option, because, in these types of languages, the program can get an idea about the types of variables they are using within the program. Let’s have a look at an example:-

public class Students {

 String name;

 String age;

 public Students(String name, String age){


 public void myfunction()


  System.out.println(“Hello I’m a :” +name);


 public void myage()


  System.out.println(“Hello my age is:” + age);


On the other hand, Python is a dynamically typed programming language. It means that whenever you write a program in Python. There is no need to declare the type of variables you will use within your program. In Python, the interpreter will check the types of variables at runtime.

Therefore Python is offering the most straightforward syntax that is close to plain English like pseudocode. Apart from that, there is no need to use close braces and follow other syntax rules in Python.

That’s is why the beginners find it the most user-friendly programming language. Let’s have a look at a similar example that we have written using the Java syntax. This time we will use Python programming to write the same program. 


Class Students:

  def_init_(mysillyobject, name, age);


  def myfunction(abc) :

    print(“hello I’m a “+

  def myage(abc) :

    print(“hello my Color is ” + abc.age)

p1 = Students (“Gurmeet”, “24”)



When it comes to python vs java performance, Java is quite faster than Python if we compare them based on their performance. It is using the JVM that helps Java to run faster on any platform. It means that whenever the speed is the crucial factor in your project, then you should opt for Java rather than Python. The reason behind the speed of Java is if we declared the data type within the program. Then the interpreter does not need to analyze the data type on run time. 

On the other hand, Python is considered as one of the slow programming languages in the world. It is slower than C and C++. Python is an interpreter itself. Therefore it analyzes the data type on run time. That’s why an extra process makes it a slow programming language. This point is also to showcase the Java vs python speed comparison. If you want to make a faster system, then don’t choose the Python. 

Easier to learn

Java is quite complex to learn as compared with Python. The reason is Java follows the strict syntax and pattern to write the program. If you miss the single curly braces of the semicolon, then your program will not run anymore.

But if you start learning the Object-oriented programming languages from scratch, then Java is a good option for you. Java has community support where you can get in touch with other developers. Those developers will help you to solve your queries. 

On the other hand, Python is easy to learn for beginners. Its syntax is quite similar to plain English. Python is an open-source programming language. Therefore you can find the massive community support with Python.

If you are a beginner, then you can learn Python with little or no effort. You can find the proper documentation, beginners guide, FAQs, Python books, and a lot more on their official site. All these will help you to get an excellent command of Python programming.

Web Development

If we talk about the web development uses of Java and Python. Then both of these programming languages are widely used in the backend web development process. In the backend web development, the system is designed to run on the server instead of the client browser.

There are lots of frameworks in the world that are making the developer task more straightforward than ever before to develop complex server-side applications. Java is offering excellent support to create server applications. It has a backend framework that is providing a massive ecosystem to develop backend applications. The website developed in Java is quite safer but slower.

On the other hand, Python is offering the Django and Flask framework. Both of these frameworks are widely used to develop backend applications. Flask is the micro web framework.

On the other hand, Django is a full-featured framework that allows you to create powerful backend applications. It also provides efficiency and security to users.

Django offers the ORM layer, which is quite helpful in dealing with the database to perform various data-related operations. In this comparison between Java and Python, Python is getting a slight edge over Java. 

Machine Learning

Machine learning is getting popular these days. Nowadays, the programmer prefers those languages that are compatible with machine learning. Java is one of the preferred programming languages for machine learning. The reason is that it is quite easy to do debugging in Java.

The programmers are using it on a large scale and enterprise-level applications. It is also widely used in deep learning so that here we can find the difference between Java vs Python deep learning. 

Python is the most popular and widely-used programming language for machine learning. Nowadays, programming for different disciplines is using Python for doing experiments in machine learning.

It also helps them to utilize the power of AI in their respective fields. Nowadays, more than 70% of development in AI and ML is done with Python because Python is offering vast ecosystems and libraries for ML and AI. Apart from that, it is one of the best languages for deep learning. 

Data Science

We can’t use Java directly in data science. But nowadays, it is used to create customized Hadoop for data science projects. These days data science companies need full command over the data science project. That’s why they prefer to rely on their Hadoop instead of pre-created Hadoop. Hadoop is the data warehouse, data scientist uses it to store a large amount of data collected from different sources. 

On the other hand, Python is the most popular programming language for data science. It is replacing the use of R in data science. We can perform lots of functions in data science with the help of Python programming. All the programming part in data science can be done with Python only.


Java Architecture

It uses the JVM i.e., Java Virtual Machine. It offers the run time environment to operate the Java code. JVM converts the Java Code into the bytecode and then the bytecode into machine language. JVM uses the JRE for the whole process. 

Python Architecture   

Python uses the interpreter that is used to translate the source code into the machine-independent bytecode (.pyc) and stores .pyc file __PyCache__ folder. Whenever you run the program, then the interpreter uses this byte and doesn’t translate it again. The exact bytecode shipped to PVM to execute the program. 

Job Opportunities

Java and Python both are offering lots of job opportunities and career options to the programmers. If you get decent command over either of these languages, then you can start your career as a programmer. Here are some of the job option is Java and Python
