Software Development is a dynamic field.
In Software Industry there are lots of new technologies that come-in emerge as giants, rise to fame and then eventually fade away.
Developers need to constantly be learning new skills to stay relevant.
According to TIOBE Index for July 2018, JAVA still tops the chart followed by C, C++ and Python.
But, yes it is true that JAVA is getting down these days with python emerging as next giant and growing at a brisk rate.
Java is over 2 decades old, used by millions of developers and billions of devices worldwide, and able to run on any hardware and operating system through the Java Virtual Machine. All Android apps are based on Java and 90 percent of Fortune 500 companies use Java as a server-side language for backend development but the number of jobs have decreased over-time.
One the other hand Python is a general-purpose programming language used for web development and as a support language for software developers. It’s also widely used in scientific computing, data mining and machine learning. The continued growth and demand for machine learning developers may be driving the popularity of Python.
Hence, we can conclude that the boom of Artificial Intelligence, Machine Learning and Data Mining has led to the downfall of JAVA. But then again, it won’t be obsolete.
