In the world of computer programming, developers have a plethora of options when it comes to choosing a programming language. However, Python and Java are facing severe competition for the top position of the most popular programming languages.

Though Java reigns top rank in the development industry, Python has shown significant advancement in recent times, and hence they are in head-on competition mode. Both Java and Python are the hottest programming languages in the market due to their versatility, efficiency, and automation capabilities.

So, if you’re a newbie here and are confused about choosing between the legendary Java and trending Python, then this article will provide insights to find out which one fits your goal better to give a great start to your career in 2020.

So, here we go!

What is Java?

A statically typed widely used general-purpose programming language; it is based on the simple concept of write once and runs anywhere (WORA). Java is an object-oriented programming language and is designed to run on many platforms such as Windows, Mac OS, Linux, and more.

What is Python?

An interpreted, high-level, general-purpose programming language, it is one of the most powerful object-oriented programming languages. Python is a robust language with automated memory management. It is one of the most preferred languages among developers because it is highly readable, practical, and easy to understand.

Now let’s have a look at various parameters to compare Python and Java:


Java is faster than Python as it is compiled and takes comparatively less time to execute code. Whereas, Python being an interpreted language, determines the type of data at run time, which makes it relatively slower.

•Web Development

Java and Python programming languages are widely used in the backend web development process. Spring is the most well-known backend framework of Java, having a massive community and a large community of developers. Spring is used by many large enterprises such as Orange, Dell, GE, and others. It is considered as a reliable choice for building enterprise-level applications. Whereas, Django and Flask are the two widely used frameworks for developing backend applications offered by Python. Django is a full-featured framework that enables you to create powerful backend applications, and Flask is a micro web framework. Hence, Python is getting a slight edge over Java when it comes to web development.

•Game Development

Though neither Python nor Java can compete with C++/C# when it comes to game development, yet they are reliable. Game development is a field that requires the optimal possible performance to enable users with seamless execution, and either Java or Python isn’t capable of complying with that.

JMonkeyEngine is a popular open-source game development engine built on Java. It enables programmers to develop a game with minimal graphics and a simple setup. Also, Java-based OpenGL is suitable for experimenting with computer graphics and developing the game from scratch.

However, Python isn’t considered a healthy choice for game creation on its own, but various frameworks like Panda3d, Cocos, Pygame, and more are used as a tool for building games with Python.

•Machine Learning

Machine Learning is the hottest trend these days. Python is the best-suited and the most favorable programing language for Machine Learning.

Python’s a fully-fledged general-purpose programming language having simple and easy to learn syntax makes it best-suited and popular programming language for machine learning. Keras, TensorFlow, Sickit-Learn, and Pytorch are the most popular frameworks written in Python.

While Java is also considered as one of the preferred languages when it comes to Machine Learning, Weka, Massive Online Analysis (MOA), Deeplearning4, MALLET, ELKI are the most used Machine Learning Libraries in Java.


So, with this information, we hope you might have a clear idea about which one interests you and why you should opt for pursuing it as your profession. Java and Python are offering ample of job opportunities and career options to the job aspirants. So, if you get decent command over either of the languages, you can kick start your career as a developer. If you’re looking to develop large enterprise applications, consider enrolling for the Java training course and get practical knowledge from industry experts.

PVS-Studio static analyzer team, which until recently was searching for bugs and potential vulnerabilities only in C, C++, and C# code, has prepared a new version of their tool for Java code as well. Despite the fact that in the Java world there is already a number of static analysis tools, developers believe that their analyzer can be powerful and will be a good competition.

In this article I want to tell you about the experience of developing one unpretentious game for Android, which has repeatedly paid off at the development stage!

We started developing the game in the 10th grade. Before that, we had no experience in developing and promoting mobile games. There were only basic knowledge of Java and a little experience of creating websites. And that's all!

In modern software very often there is a need to perform various operations with all kinds of money. However, until now, I have never found documentation, which would have brought together the basic rules for presenting amounts and implementing financial calculations. In this article, I will try to formulate those rules that have been compiled on the basis of personal experience.

image How does the JVM create new objects? What exactly happens when you write a new Object ()?
At conferences, it is periodically told that the allocation of objects uses the thread-local allocation buffer (TLABs): memory areas allocated exclusively to each thread, creating objects in which is very fast due to the lack of synchronization.
But how correctly to choose the size of TLAB'a? What to do if you need to allocate 10% of the size of TLAB'a, but only 9% is free? Can an object be allocated outside TLAB? When (if) is the allocated memory set to zero?
Having asked these questions and did not find all the answers, I decided to write an article to correct the situation.
Before reading it, it's useful to remember how some garbage collector works

Technology: Querydsl is a java based framework which enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files they can be constructed via a fluent API like Querydsl.we can use Querydsl in java application for creating all kinds of sql statements.Querydsl has various plugins for JPA,mongoDb, SQL,lucene and also for java collections.

Do you know how much memory the string has? I have heard all kinds of answers to this question, ranging from "do not know" to "string has 2 bytes". Here are some more questions: How much space does empty string take? How much space does the class object of Integer take? How much space will take your own class object with three Integer fields? It is funny, but none of my Java programmer friends could answer these questions ... Most of us do not need it, and nobody will think about it in the real java projects. After all, this is the same as you would not know the engine capacity of vehicle that you drive every day. You can be a great driver and did not even know what 2.4 or 1.6 means on your car. But I am sure that there are few people who are not familiar with the meaning of these numbers. So why do java programmers know so little about this part of their tool?

Integer vs int

We all know that in java - everything is an object. Except, perhaps, primitives and references to the objects themselves. Let us consider two typical situations:

This article explains how to implement some data structures in Java. It will be useful for beginners that use a programming language Java, as well as those who already know how to write a new ArrayList (), but have little knowledge what is happening inside.


Let us talk about the ArrayLists

ArrayList implements the List interface. As we know, Java arrays have a fixed length, and after the array is created, it cannot increase or decrease. ArrayList can change its size at runtime, but it does not necessarily indicate the size when an object is created. The elements of ArrayList can be any types, including null.
