Java中用正则表达式验证邮政编码和EMail

public class MatchZipCodes
...{

  public static void main(String args[])
  ...{
    isZipValid("45643-4443");
    isZipValid("45643");
    isZipValid("443");
    isZipValid("45643-44435");
    isZipValid("45643 44435");
    isZipValid("45643-2123");
    isEmail("[e-mail]");
  }

  public static boolean isZipValid(String zip)
  ...{
    boolean retval = false;
    String zipCodePattern = "\d{5}(-\d{4})?";
    retval = zip.matches(zipCodePattern);

    String msg = "NO MATCH: pattern:" + zip + "              regex: "
                 + zipCodePattern;

    if (retval) ...{
      msg = "MATCH   : pattern:" + zip + "              regex: "
            + zipCodePattern;
    }

    System.out.println(msg + " ");
    return retval;
  }

  public static boolean isEmail(String email)
  ...{
    boolean retval = false;
    String emailPattern = "^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+[.]([a-zA-Z0-9_-])+";
    retval = email.matches(emailPattern);
    String msg = "NO MATCH: pattern:" + email + "              regex: "
                 + emailPattern;

    if (retval) ...{
      msg = "MATCH   : pattern:" + email + "              regex: "
            + emailPattern;
    }

    System.out.println(msg + " ");
    return retval;
  }
}

zipCodePattern好像有点问题，博主把程序跑过没？
