Splitting a string with a space without removing the space?

Question

Something like: How to split a String with some separator but not removing that separator in Java?

I need to take "Hello World" and get ["Hello", "," World "]

Answer 1

You can use regex, although this is probably brute force:

StringCollection resultList = new StringCollection(); Regex regexObj = new Regex(@"(?:\b\w+\b|\s)"); Match matchResult = regexObj.Match(subjectString); while (matchResult.Success) { resultList.Add(matchResult.Value); matchResult = matchResult.NextMatch(); } 

Answer 2

You can use Regex.Split() . If you attach a template to capturing parentheses, it will also be included in the result:

 Regex.Split("Hello World", "( )") 

gives you exactly what you wanted.

Answer 3

If you split only at the border of the word, you will get something very close to what you are asking.

  string[] arr = Regex.Split("A quick brown fox.", "\\b"); 

arr [] = {"," A ",", "quick", "," brown ",", "fox", "." }
