Usage

From source file:Main.java

    StringBuilder phrase = new StringBuilder("java2s.com");
    int position = phrase.lastIndexOf(".com");

    System.out.println(position);
}

From source file:txyd.util.StringUtils.java

public static void main(String[] args) {
    System.out.println(5 % 5);//  ww  w.  j a v  a  2  s . c o m
    System.out.println(isLong("1111111111111111111111"));
    StringBuilder sb = new StringBuilder("1_2_3_4_5_");
    System.out.println(sb.substring(0, sb.lastIndexOf("_")));
}

 * N.b. do not call this method from a persistent program, because it

 * <p>
 * Any long-running program should use the lower-level methods in this

 * instances).
 * </p> <p>
 * This method executes with all JCreole privileges.

 * This method sets up the following htmlExpander mappings (therefore you
 * can reference these in both Creole and boilerplate text).<p>
 * <ul>
 *   <li>sys|*: mappings for Java system properties
 *   <li>isoDateTime
 *   <li>isoDate
 *   <li>pageTitle: Value derived from the specified Creole file name.

 *
 * @throws IOException for any I/O problem that makes it impossible to
 *         satisfy the request.
 * @throws CreoleParseException
 *         if can not generate output, or if the run generates 0 output.
 *         If the problem is due to input formatting, in most cases you
 *         will get a CreoleParseException, which is a RuntimException, and
 *         CreoleParseException has getters for locations in the source
 *         data (though they will be offset for \r's in the provided
 *         Creole source, if any).
