Welcome to JavaRanch
You can't replace part of a String, only replacing the String with a different String.

Maneesh Godbole reminded me about the replace methods in the java.lang.String class; these might produce the result you require. They don't really replace anything, but create a new String with the alterations.

Assuming this is in reference to the (regex related) replaceXXX() methods of the java.lang.String class, you can actually specify a word border with the "\\b" tag.... so, if the pattern to be replaced is "\\bam\\b", this will only replace instance of "am" which are itself a word, and not attached to a word, hence, "amammmam" won't match.
