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

As I understood the question, you should do something like this, but I'm not sure I totally got what you asked:

yourString = firstString + replacingString + endString;

If you want the "replaced" string:

replacedString = wholeString.substring(0, wholeString.lastIndexOf(endString) - 1);
replacedString = tempString.substring(firstString.length() + 1);
