Sorting of Strings in a UserDefined Way

[Sarita KShetty]

Sorting of Strings in a UserDefined Way :

I have a Set of Strings in the order{This is the order in which sorting is to be done}
"Public","InternalUse","Confidential"
My requirement is that i Have to sort the column containing the above String Values in the order mentioned above.


For example: If I have
"Internal Use","Confidential","Public" as values in the column

After sorting it should be :


"Public", "InternalUse","Confidential"

Can you create a Comparator which will support your sorting order?
Can you put your Strings as keys in a Map and return a Double which indicates the sorting order? Using a Double rather than Integer allows you to insert intermediate values later on.

[David Newton]

Why not just send them to the page in that order?

Is there any other value associated with the strings?

[Paul Clapham]

Why not just use an enum with those three values?
