hi all
Class.forName(int[]) throws exception ClassNotFound Exception. I need to Class instance of primitive types . How do i do it?

[David O'Meara]

Try int[].class

primitives is not an object, hence you cannot get a class from int. If you looking at primitve wrappers then it's the Integer class that you require.

Interestingly, it looks like this may also work, but confuse the heck out of anyone who has to support it:

Class.forName("[I");

Thanks ..
[B for byte array
[I for int array
[F for float array etc works fine

   public static void main(String ar[]) {
        try {
            Class byteclass = Class.forName("[B");
            System.out.println(byteclass.isArray());
            byte[] bb = (byte[])Array.newInstance(byteclass.getComponentType(),4);
            bb[3] = 8;
            System.out.println(bb[3]);
        } catch (Exception e) {
            e.printStackTrace();
        }
 
    }

int[].class didn't work?

[David O'Meara]

I really recommend using int[], I really do. Anyone looking at the code after this won't have any idea what "[I" is. They may even slap you in the street
