public static String regexChecker(String theRegex, String str2Check) { // You define your regular expression (REGEX) using Pattern Pattern checkRegex = Pattern.compile(theRegex); // Creates a Matcher object that searches the String for // anything that matches the REGEX Matcher regexMatcher = checkRegex.matcher(str2Check); // Cycle through the positive matches and print them to screen // Make sure string isn't empty and trim off any whitespace while (regexMatcher.find()) { if (regexMatcher.group().length() != 0) { return regexMatcher.group().trim(); // // You can get the starting and ending indexs // System.out.println("Start Index: " + regexMatcher.start()); // System.out.println("Start Index: " + regexMatcher.end()); } } return ""; } input : say("say hello 4 times"); say("say moti rulz"); say("say shouryuken 5 times"); output : hello hello hello hello moti rulz shouryuken shouryuken shouryuken shouryuken shouryuken _________________ MB over and out  | |
