Java Regex not recognizing the string

Question

I am trying to find if a string fits the format "name"/"version". Here is an example of what I expect to have.

VideoPart/1.2

I've tried many regexes. The closest I have come is this:

"[a-z,A-Z,0-9,\\.]*/[a-z,A-Z,0-9,\\.]"

but it doesn't recognize the format. I am being specific in this regex because I don't want anything more than just one forward-slash. Thanks!

I am under the impression that commas are like or's. The text can be any combination of those. — Stephen D

[a-z,A-Z,0-9,\\.] is the same as [a-zA-Z0-9,.]. You don't have to escape periods inside character classes. — Keppil

@StephenD Elements inside the character class are grouped together already, so [a-zA-Z0-9\.]* is the same thing. Also you may want to use + instead of * otherwise you could match single forward-slashes — Hunter McMillen

Try this:

\\b[a-zA-Z0-9.]+[/][a-zA-Z0-9.]+\\b
