Finding All Occurrences of a Pattern

String pattern = "\\st(\\w)*o(\\w)*"; Pattern regPat = Pattern.compile(pattern); String text = "The words are town tom ton toon house."; Matcher matcher = regPat.matcher(text); while (matcher.find()) { String matchedText = matcher.group(); System.out.println("match - " + matchedText); }

The output printed from our System.out.println()statements will be the following:

town tom ton ...
