How to create an array of arrayList

[neha priya]

hello everyone,

i want to create an array of arrayList of type EventRow...i tried this

   List<EventRow>[]hmevents=new ArrayList<EventRow>[10];   

but it is giving the error

  Cannot create a generic array of ArrayList<EventRow>  

am unable to understand this error...please help me suggest me some way by which i can create an array of arrayList of type EventRow

You can't. I think there is an explanation in the Java™ Tutorials, but I can't remember whether it is in this part or this part.

[akhter wahab]

List<EventRow> someName = new ArrayList<EventRow>();    

list is dynamic you can't give its length.

thanks for the replies...could you please suggest me some way through which i can have a substitute for array of arraylist of type EventRow?

why you need substitute ?

[Prabhakar Reddy Bokka]

Java 5 does not permit the construction of generic arrays.
Go through the link below.

@akhter wahab:thanks for replying..i need a substitute because my implementation demands that...

i am filtering out rows and putting them in an arraylist(say events)...now i am having a hashmap that is declared as

 HashMap<Integer,List<EventRow>>tabToEventsMap= new HashMap<Integer,List<EventRow>>();   

the Integer corresponds to 1st filter,2nd filter,3rd filter and List contains the corresponding filter rows..

so i needed to have an arraylist of type eventrow...i don't know if am able to explain my point clearly.

thanks
