How do I trim a file extension from a String in Java?

Question

What's the most efficient way to trim the suffix in Java, like this:

title part1.txt

title part2.html

=>

title part1

title part2

Answer 1

This is the sort of code that we shouldn't be doing ourselves. Use libraries for the mundane stuff, save your brain for the hard stuff.

In this case, I recommend using FilenameUtils.removeExtension() from Apache Commons IO
