trim

The trim() function removes both the trailing and leading space, however, if I only want to remove the trailing space of a string, how can I do it? Since JDK 11 If you are on JDK 11 or higher you should probably be using stripTrailing() . Earlier JDK versions Using the regular expression \s++$ , you can replace all trailing space characters (includes space and tab characters) with the empty string ( "" ). final String text = " foo "; System.out.println(text.replaceFirst("\\s++$", "")); Output foo Online demo. Here's a breakdown of the regex: \s – any whitespace character, ++ – match one or

Among other changes, JDK 11 introduces 6 new methods for java.lang.String class: repeat(int) - Repeats the String as many times as provided by the int parameter lines() - Uses a Spliterator to lazily provide lines from the source string isBlank() - Indicates if the String is empty or contains only white space characters stripLeading() - Removes the white space from the beginning stripTrailing() - Removes the white space from the end strip() - Removes the white space from both, beginning and the end of string In particular, strip() looks very similar to trim() . As per this article strip*()

Is there any way to cut a video (mp4 or 3gp) on android, like use only the last 5 seconds of the movie... on iphone this is possible using the AVAssetExportSession but on android I haven't found anything similar, just maybe some references to ffmpeg library which seems complicated. Is there any easier way to do it? Sebastian Annies You can do this with my mp4parser library. Have a look at the ShortenExample it does exactly what the name suggests. Since the library cannot re-encode the video it can only cut the video at I-frames. So the points in time where you can make a cut are quite coarse.

Say I have a table column that has results like: ABC_blahblahblah DEFGH_moreblahblahblah IJKLMNOP_moremoremoremore I would like to be able to write a query that selects this column from said table, but only returns the substring up to the Underscore (_) character. For example: ABC DEFGH IJKLMNOP The SUBSTRING function doesn't seem to be up to the task because it is position-based and the position of the underscore varies. I thought about the TRIM function (the RTRIM function specifically): SELECT RTRIM('listofchars' FROM somecolumn) FROM sometable But I'm not sure how I'd get this to work

I have a text string that starts with a number of spaces, varying between 2 & 4. What is the simplest way to remove the leading whitespace? (ie. remove everything before a certain character?) " Example" -> "Example" " Example " -> "Example " " Example" -> "Example" coobird The lstrip() method will remove leading whitespaces, newline and tab characters on a string beginning: >>> ' hello world!'.lstrip() 'hello world!' Edit As balpha pointed out in the comments , in order to remove only spaces from the beginning of the string, lstrip(' ') should be used: >>> ' hello world with 2 spaces and a tab

What is the best way to remove all spaces from a string in SQL Server 2008? LTRIM(RTRIM(' a b ')) would remove all spaces at the right and left of the string, but I also need to remove the space in the middle. Simply replace it; SELECT REPLACE(fld_or_variable, ' ', '') Edit: Just to clarify; its a global replace, there is no need to trim() or worry about multiple spaces for either char or varchar : create table #t ( c char(8), v varchar(8)) insert #t (c, v) values ('a a' , 'a a' ), ('a a ' , 'a a ' ), (' a a' , ' a a' ), (' a a ', ' a a ') select '"' + c + '"' [IN], '"' + replace(c, ' ', '') +
