Fucking Java Matcher & String class. Please add this method to String class.

RegexUtils.java

/**
 * @author Keesun Baik
 */
public class RegexUtils {

	public static String[] match(String input, String regexp) {
		Matcher matcher = Pattern.compile(regexp).matcher(input);
		String[] results = new String[matcher.groupCount() + 1];

		while (matcher.find()) {
			for(int i = 0 ; i < results.length ; i++) {
				results[i] = matcher.group(i);
			}
		}

		return results;
	}
}

RegexUtilsTest.java

/**
 * @author Keesun Baik
 */
public class RegexUtilsTest {

	@Test
	public void match() {
		String regexp = "([^:]+):([0-9]+)?(\\+)?:([^:]+)?:?([\\s\\S]*)?";
		String input = "111:222+:444:555";
		String[] results = RegexUtils.match(input, regexp);
		assertThat(results.length, is(6));
		assertThat(results[0], is(input));
		assertThat(results[1], is("111"));
		assertThat(results[2], is("222"));
		assertThat(results[3], is("+"));
		assertThat(results[4], is("444"));
		assertThat(results[5], is("555"));
	}
