How to look for a particular phrase in a document???

Question

Hey guys, I'm a little new at this thing... I need to figure out a way to make Java search through a document looking for instances of particular phrases, and replacing them with something else. For example, have it look for "A B C" and replace each such combination of words with "D E F". The search/replace needs to look for a few different phrases at once.

String.replaceAll is a fine answer, but you are creating Strings left, right & center, tis best to use a StringBuilder/Buffer.
    private static void replaceAll( StringBuilder sb, String search, String replace ) {
     int index = sb.indexOf( search, 0 );
     while( index >= 0 ) {
         sb.replace( index, index+search.length(), replace );
         index = sb.indexOf( search, index );
    }
