Issue with regex replaceAll

Question

I'm trying to turn, a/b/c.x.y into abc. However there seems to be an issue with my regular expression, specifically with '\\.*'.

 "a/b/c.x".replaceAll( "/|\\.*", "" );

yields:

 "abcx"

Any insight would be great, thanks!

Is that the only format it will ever be in? Because a/b.x/c would require some different logic. — TheZ

You're replacing any slash or "any number of dots" with an empty string.

I suspect you mean any slash or "a dot followed by any number of any characters" which would be:

replaceAll("/|\\..*", "");

That certainly works for me with the sample value.

Just what I was typing. Rule isn't clear from the question, but the * implies this is what the OP was after.

Your current regex matches a forward slash OR zero or more periods. I assume that you want to match forward slash OR a period plus anything after it. For that, you want

"/|\\..*"
