Casting Double object to int

How can I convert from a Double object to an int? The following code works but seems slightly unconventional (with casting twice):

Double d = new Double(4.0);
int i = (int)(double)d;

When I try int i = (int)d, I get an error from Eclipse (Cannot cast from Double to int), which makes sense. Nevertheless, is there a simpler way of converting a Double object to an int?

In your case you use 

Double.intValue()

as a method to convert the Double Object to Integer.

If you cast double to int you will loss decimal value.. so 4.99 double become 4 int. If still want to convert than try-

int i = d.intValue();
