Convert from enum ordinal to enum type

Question

I've the enum type ReportTypeEnum that get passed between methods in all my classes but I then need to pass this on the URL so I use the ordinal method to get the int value. After I get it in my other JSP page, I need to convert it to back to an ReportTypeEnum so that I can continue passing it.

How can I convert ordinal to the ReportTypeEnum?

Using Java 6 SE.

Answer 1

To change an ordinal into its enum represantation you might require to try this:

ReportTypeEnum value = ReportTypeEnum.values()[ordinal];

Please mark the array bounds.

Remark that every call to values() delivers a newly cloned array which sways impact appearance in a negative fashion. You may require to cache the array if it's performing to be called frequently.
