Java: Remove full stop in string

Question

I want to delete all the full stops ( . ) in a string.

Therefore I tried: inpt = inpt.replaceAll(\".\", \"\");, but instead of deleting only the full st

Answer 1

Don't use replaceAll(), use replace():

inpt = inpt.replace(".", "");

It is a common misconception that replace() doesn't replace all occurrences, because there's a replaceAll() method, but in fact both replace all occurrences. The difference between the two methods is that replaceAll() matches on a regex (fyi a dot in regex means "any character", which explains what you were experiencing) whereas replace() matches on a literal String.
