ArrayList

[renu richard]

Hi,
is there something like this

ArrrayList<int> al = new ArrayList<int>();

Yes, the declaration of an ArrayList looks something like that.

Hi Renu,

I think what you're asking is whether you can use a primitive like "int" as a generic type parameter to a class. The answer is no, you can't; Java doesn't support that.

Hi,

One can only use reference types as the Type argument while using generics. You can make your own generic classes but cannot use primitives as Type arguments. You can use their wrappers as Type arguments and put the primitives directly into the ArrayList with the help of autoboxing.
