Question

I have a java string, which has a variable length.

I need to put the piece '<br>' into the string, say each 10 characters.

For example this is my string:

`this is my string which I need to modify...I love stackoverlow:)` 

How can I obtain this string?:

`this is my<br> string wh<br>ich I nee<br>d to modif<br>y...I love<br> stackover<br>flow:)` 

Thanks

Something like:

public static String insertPeriodically(     String text, String insert, int period) {     StringBuilder builder = new StringBuilder(          text.length() + insert.length() * (text.length()/period)+1);      int index = 0;     String prefix = '';     while (index < text.length())     {         // Don't put the insert in the very first iteration.         // This is easier than appending it *after* each substring         builder.append(prefix);         prefix = insert;         builder.append(text.substring(index,              Math.min(index + period, text.length())));         index += period;     }     return builder.toString(); }
