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

replaceAll takes a regular expressions as an argument, and . in a regex means "any character".

You can use replace instead:

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

It will remove all occurences of ..

Answer 2

replaceAll use a regex, please use the following:

inpt = inpt.replaceAll("\\.", "")

Answer 3

I think you have to mask the dot

inpt = inpt.replaceAll("\\.", "");

Answer 4

String#replaceAll(String, String) takes a regex. The dot is a regex meta character that will match anything.

Use

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

it will also replace every dot in your inpt, but treats the first parameter as a literal sequence, see JavaDoc.

If you want to stick to regex, you have to escape the dot:

inpt = inpt.replaceAll("\\.", "");

Answer 5

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.
