regular expression to match one or two dots [duplicate]
What is the regular expression for . and .. ?
if(key.matches(".")) {
do something
}
The matches accepts String which asks for regular expression. Now i need to remove all DOT's inside my MAP.
Solution 1:
. matches any character so needs escaping i.e. \., or \\. within a Java string (because \ itself has special meaning within Java strings.)
You can then use \.\. or \.{2} to match exactly 2 dots.
Solution 2:
...
[.]{1}
or
[.]{2}
?
