The right and wrong approach to writing Java Enums
public interface Base<T> {

    public T fromValue(String v);

}

public enum AddressType implements Base<AddressType> {

    NotSpecified("Not Specified."),

    Physical("Physical"),

    Postal("Postal");

    private final String label;

    private AddressType(String label) {
        this.label = label;
    }

    public String getLabel() {
        return this.label;
    }

    @Override
    public AddressType fromValue(String v) {
        return valueOf(v);
    }
}

AddressType type = AddressType.Postal.valueFrom("Physical");
