Commonly used regular expression verification tool class (instance code)

There are not many things, but the general projects are enough.

public class RegularUtil {
  //ID card  public static final String REGEX_ID_CARD = "^[1-9]\\d{5}[1-9]\\d{3}((0\\d)|(1[0-2]))(([0|1|2]\\d)|3[0-1])\\d{3}([0-9]|X)$";
  //Verify the email address  public static final String REGEX_EMAIL = "^([a-z0-9A-Z]+[-|\\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\\.)+[a-zA-Z]{2,}$";
  //Phone number  public static final String REGEX_PHONE = "0?(13|14|15|17|18)[0-9]{9}";
  //Chinese character  public static final String REGEX_TRUENAME = "^[\\u4e00-\\u9fa5]*$";
  //bank card  public static final String BANKNUMBER="^([0-9]{16}|[0-9]{19})$";

  public static boolean isPhone(String mobiles){
    if ((mobiles)){
      return false;
    }else{
      return (REGEX_PHONE);
    }
  }
  public static boolean isTel(String mobiles) {
    if ((mobiles)) {

    }
  }
}
