Java Solutions
Solution 1 - Java
If you really should use Double instead of double you even can get the int Value of Double by calling:
Double d = new Double(1.23);
int i = d.intValue();
Else its already described by Peter Lawreys answer.
Solution 2 - Java
All other answer are correct, but remember that if you cast double to int you will loss decimal value.. so 2.9 double become 2 int.
You can use Math.round(double) function or simply do :
(int)(yourDoubleValue + 0.5d)
Solution 3 - Java
double myDb = 12.3;
int myInt = (int) myDb;
Result is: myInt = 12
Solution 4 - Java
try casting the value
double d = 1.2345;
long l = (long) d;
Solution 5 - Java
int average_in_int = ( (Double) Math.ceil( sum/count ) ).intValue();
