Thread: Replacing text after a certain character or symbol in a text file

Can anyone lead me to the right direction on how to do this:

I want toreplace all text after a certain character or symbol

Say a line in the text file contains ":"

I want everything after the ":" on that line to replaced with other text

Store the entire line of text to a String variable.
Use String method(s) to find the location/index of the certain character or symbol,
Use other String method(s) to replace characters after the certain character or symbol with the desired characters.

There are 2 or 3 other approaches that occur to me. Perhaps those or variations on the above outline will come to you as you learn about the available String methods on the String API page.
