Subject [jira] [Commented] (LANG-1108) Function to replace multiple whitespaces by a character and trim
Date Mon, 05 Dec 2016 02:45:58 GMT

    [ https://issues.apache.org/jira/browse/LANG-1108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15721039#comment-15721039
] 

Bruno P. Kinoshita commented on LANG-1108:
------------------------------------------

Oh, today I learned :-)

I think this solves the first part, and the remainder can be solved via other existing functions
too?

{code}
    public static void main(String[] args) {
        String value = "   This is     quite the   test.  ";
        System.out.println(value);
        String value2 = StringUtils.normalizeSpace(value).replace(' ', '_');
        System.out.println(value2);
    }
{code}

Results in

{noformat}
   This is     quite the   test.  
This_is_quite_the_test.
{noformat}

So I think this can be achieved with existing functions from [lang] and JRE. What do you think
[~djmj]?

> In form applications where user can input data its very often not wished to have successive
whitespace characters.
> A function that will replace multiple whitespace characters with a single space (or passed
string/character) would be a nice feature since I myself repeat this method in many applications.
> Something like a shortcut for:
>     value.replace("\\s+", " ").trim()
