Because I need to insert a <font ...> tag in front of every letters of every found given word and a closing</font>. The word tested is 'create'(6 letters) and it appears something like 830 times.
After using a RegEx, I got the positions of those letters so I need substrings of the main string to fill a StringBuilder with the parts not containing the letters of the words. This loop is not there just to be fancy. ----------------------------------------------- Well, if I wrote a recursive call which never returns, I could bring down any system. Can you tell us why you need loop 5000 times? Instead of using StringBuilder, did you consider using StringBuffer as an alternative? Have you check all the available method within String class itself? This is the checklist I can think of for now, hope it helps.
