    Default StringBuffer Problem

    I have user input in a StringBuffer. I need to search for the word "the" and replace every occurrence with another string, "zee." How do I do this?

    int theStart = sentence.indexOf("the");
    		int theEnd = theStart + "the".length();
    		sentence.replace(theStart, theEnd, "zee");

    What I have only works for the FIRST occurrence.
    Thanks!

    only works for the FIRST occurrence.
    Put the code in a loop and have the indexOf method start each search past the changed location.
    Or read the API doc for the String class to see if it has other useful methods.
    If you don't understand my answer, don't ignore it, ask a question.

    take a peek at java.util.regex?

    edit:
    Nevermind, follow Norm's advice and look at the Java String API

    If the sentence variable is a StringBuffer, then you'll have to use its methods.
