### Question:
AdapterUtils { public static Boolean parseBoolean(String s) { Objects.requireNonNull(s); Boolean b = BOOLEAN_STRINGS.get(s.toUpperCase()); if (b == null) { throw new ParserException( "Cannot convert \"" + s + "\" to " + Boolean.class.getName() + " type."); } return b; } private  AdapterUtils(); static Boolean parseBoolean(String s); static Date parseDate(String s); static LocalDate parseLocalDate(String s); static LocalDateTime parseLocalDateTime(String s); static String withoutDecimals(String s); static Enum<?> findEnumIgnoreCase(Class<? extends Enum<?>> enumType, String name); static Class<?> uncheckedClassForName(String s);  }### Answer:
