You really don’t need to know any java. I don’t know java either.

Even if you’re doing java interop, it’s quite easy to figure it out.

Last time I looked about file IO it involves calling out to some Java class that I had no clue about as I don't use Java. All the doc of the time just assumed you should be able to figure this all out.

Edit: it's been like 5 years

The docs are better now (eg https://clojure-doc.org/articles/cookbooks/files_and_directo... ) but you still need to follow a Javadoc link every now and then for the full story.

Alternatively you can use a library such as https://github.com/babashka/fs .

I agree with the GP that you don't need to know any Java.

This was my experience too, at about the same time. I should really dig back into it at some point.

Java frolicks in opaqueness.
