I just want to add a space between each character of a string. Can anyone help me figuring out how to do this?
E.g. given "JAYARAM", I need "J A Y A R A M" as the result.

You can use the regular expression '..' to match each two characters and replace it with "$0 " to add the space: s = s. replaceAll("..", "$0 ");
To add a space between the characters of a string, call the split() method on the string to get an array of characters, and call the join() method on the array to join the substrings with a space separator, e.g. str. split('').
Select the text that you want to change. On the Home tab, click the Font Dialog Box Launcher, and then click the Advanced tab. Note: If you're using Word 2007 the tab is called Character Spacing. In the Spacing box, click Expanded or Condensed, and then specify how much space you want in the By box.
Unless you want to loop through the string and do it "manually" you could solve it like this:
yourString.replace("", " ").trim() This replaces all "empty substrings" with a space, and then trims off the leading / trailing spaces.

An alternative solution using regular expressions:
yourString.replaceAll(".(?=.)", "$0 ") Basically it says "Replace all characters (except the last one) with with the character itself followed by a space".
