Will Python replaCe JaVa ?

Is Java Dying? of course not but Python growing in popularity day by day. Each has its own strengths and weaknesses.

According to IT programming trends, Java is more popular than any other programming language in terms of number of jobs, number of existing Java developers, and overall usage statics in IT. According to the latest usage statistics posted on a popular technology survey site, Java is being used by 3.0% websites as a server-side programming language, whereas only 0.2% of websites use Python. However, all the recent reports have highlighted that the usage and popularity of Python is growing drastically compared to Java, where usage is coming down year on year.
At myTectra, we have been monitoring the trend of Python and Java since 2013 based on the number of Jobs posted in Naurki for the Bangalore region since 2013. In the below table, we can see that Java requirements are coming down year over year, whereas Python requirement has grown from 200 in 2014 to 6500+ in 2017.

Following job posting statistics from Indeed shows Python is the only programming language consistently growing, compared to Java.

Difference between Java and Python

There are three main language characteristics that make programmers more productive with Python than with Java.
In Java, all variable names (along with their types) must be explicitly declared. Attempting to assign an object of the wrong type to a variable name triggers a type exception.That’s what it means to say that Java is a statically typed language.
Java container objects (e.g. Vector and ArrayList) hold objects of the generic type Object, but cannot hold primitives such as int. To store an int in a Vector, you must first convert the int to an Integer. When you retrieve an object from a container, it doesn’t remember its type, and must be explicitly cast to the desired type.

In Python, you never declare anything. An assignment statement binds a name to an object, and the object can be of any type. If a name is assigned to an object of one type, it may later be assigned to an object of a different type. That’s what it means to say that Python is a dynamically typed language.
Python container objects (e.g. lists and dictionaries) can hold objects of any type, including numbers and lists. When you retrieve an object from a container, it remembers its type, so no casting is required.

Java is a verbose containing more words than are necessary but Python is concise expressing much in fewer words. Java is not compact but Python is a compact language.

Python  is powerful, flexible, open source language that is easy to learn, easy to use, and has powerful libraries for data manipulation and analysis. Its simple syntax is very accessible to programming novices, and will look familiar to anyone with experience in Matlab, C/C++, Java, or Visual Basic. Python has a unique combination of being both a capable general-purpose programming language as well as being easy to use for analytical and quantitative computing.

Python become a language of choice for all the current trending Technologies in IT. If the current trends continues Python will become the most sought after language and overtake the number of jobs requirement in next 2-3 years.
