If you are using Java 1.8, you can choose Stream + Lambda to implement this:

public enum Period {
    DAILY, WEEKLY
};

//This is recommended
Arrays.stream(Period.values()).anyMatch((t) -> t.name().equals("DAILY1"));
//May throw java.lang.IllegalArgumentException
Arrays.stream(Period.values()).anyMatch(Period.valueOf("DAILY")::equals);
