New Study.com courses (5/16/19)

[bluebooger]

both the intro to programming and data structures course use java

Could someone start and finish Study.com Data Structures with no prior Java knowledge? If they know some Python.

IOW, does the course review the Java concepts briefly or not?

good question

it says 

Prerequisites

There are no prerequisites for this course.

which I find amazing 

if you scroll down to -- Course Topics 
you'll see the first lesson is 

Basics of Java
Describe the fundamentals of Java and set a coding environment to test code; define important programming concepts, including pseudocode, documentation, commenting and testing.

I guess it all depends on the final exam and what you actually have to write
