I've got data say in following format (*there may be more than three types of exception)
Name,Exception,count
Jack,Null Pointer Exception,10
Jack,Number Format Exception,10
Jack,Other Exception,10
Tom,Null Pointer Exception,20
Tom,Number Format Exception,20
Tom,Other Exception,20
Dave,Null Pointer Exception,30
Dave,Number Format Exception,30
Dave,Other Exception,30
Required output is something like:
Name, Rank for Null Pointer Exception, Rank for Number format Exception...
Jack , 3 , 3 , 3
Tom , 2 , 2 , 2
Dave , 1 , 1 , 1
Any simple SPL can you suggest? Thank you.
