Java skills needed for deploying models

When thinking about deploying models on the web, I realize that I do not know Java, and I will appreciate any advice about the level of Java skills -and some guide about wich on line courses (preferably on Coursera)- should I take.

Most of the course is python / javascript based. There’s a bit of iOS and a section on android. You can get by without too much experience in java.

Here’s the only course that might be of concern to you. Expand the notes for each week and see if it fits your level.
