Replace a String between two Strings

Question

Let\'s say we have something like:

&firstString=someText&endString=OtherText

And I would like to replace \"someText\" with somethin

Answer 1

This solution checks that we're not going of the end of the string and will do it for multiple occurrences.

 int startIndex = text.indexOf(startDelim);
 while (startIndex > -1)
 {
    int endIndex = text.indexOf(endDelim, startIndex);
    String endPart = "";

    if ((endIndex + endDelim.length()) < text.length())
       endPart = text.substring(endIndex + endDelim.length());

    text = text.substring(0, startIndex) + replacementText + endPart;
    startIndex = text.indexOf(startDelim);
 }
