Regular Expression for two or more dots should be separated as dot space

I have inputs like this.

And I walked 0.69 miles. I had a burger..I took tea...I had a coffee

And my goal is to convert two or more dots to a single dot and then a space so that input become correct according to grammar proper ending. Target output is:

And I walked 0.68 miles. I had a burger. I took tea. I had a coffee

I have made a regular expression for this is as:

[\\.\\.]+

I checked it on Regex Tester it will not work as I wished. As it will also included 0.69 and ending of this line . too which I don't want. If anybody can help me in this I will be thankful to you.

You can use String.replaceAll() to accomplish this:

myString.replaceAll("\\.[\\.]+", ". ");

Your regex is slightly wrong also it should be \.[\.]+. In Java you will have to escape the \ so it will be \\.[\\.]+...

You need to pull the first \. out to match that, then 1+ \. so like

\.\.+ or Java string escaped \\.\\.+

[\.\.] Will match \ or . or \ or . witch is a redundant check on a single character.

You can use this :

String str = "And I walked 0.69 miles. I had a burger..I took tea...I had a coffee";
String result = str.replaceAll("\\.{2,}", ". ");

Output

And I walked 0.68 miles. I had a burger. I took tea. I had a coffee

This code should work 

[\.]+[\.]+

This will match 2 or more continuous periods. You can then replace each match with a period and space

You can use:

str = str.replaceAll("\\.{2,}", ". ");

RegEx Demo

\\.{2,} matches 2 or more consecutive dots and ". " replaced them by a dot and space.
