Ashwin you said, “Tools like Play Framework helps for this purpose and Java development can be done quite fast compared to some other Frameworks.”
Can you explain this a little bit, I’m confused? Can you tell me why Play Framework is better than others?
Hi Gagan, I never said Play is better than Django or Ruby. I said that it is a bit for fast in development compared to Django. I haven’t used Play, but this is what I heard other developers say about the Play framework.
You said this – “Heroku is an example of a cloud platform that uses Java. Both Microsoft Azure and Google Cloud Platform have provisions to host java applications and to also manage them efficiently.”
Nowadays I’m learning developing Python Applications, then deploying them on Cloud Computing Platforms. Do you recommend that I should also learn developing Java Applications and How to deploy them on Cloud.????????
After going through your article Ashwin, it seems to me that there are some opportunities available out there for Java Developers. Nowadays I’m primarily focused on getting my hands dirty with Python only, Do you recommend that I should also learn Java? ????????
There are opportunities for every language. Don’t learn a language just for the sake of learning it. If you think Java will be useful for you in the future, then you can definitely learn it. But, Python also has plenty of opportunities just like Java.
