Flask vs Java: What are the differences?
Developers describe Flask as "a microframework for Python based on Werkzeug, Jinja 2 and good intentions". Flask is intended for getting started very quickly and was developed with best intentions in mind. On the other hand, Java is detailed as "A concurrent, class-based, object-oriented, language specifically designed to have as few implementation dependencies as possible". Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!.
Flask can be classified as a tool in the "Microframeworks (Backend)" category, while Java is grouped under "Languages".
"Lightweight", "Python" and "Minimal" are the key factors why developers consider Flask; whereas "Great libraries", "Widely used" and "Excellent tooling" are the primary reasons why Java is favored.
