singleton

Hi,

How thread-safe is enum in java? I am implementing a Singleton using enum (as per Bloch's Effective Java), should I worry at all about thread safety for my singleton enum? Is there a way to prove or disprove that it is thread safe?

// Enum singleton - the preferred approach
public enum Elvis { 
    INSTANCE;
    public void leaveTheBuilding() { ... }
}

Thanks
