How do I cast a double to an int in Java?

Question

I'm looking at http://docs.oracle.com/javase/6/docs/api/java/lang/Double.html

I am trying

    double b = Math.sqrt(absoluteNumber);
    int c = b.intValue();

but I am getting this error:

Factorise.java:13: error: double cannot be dereferenced
int c = b.intValue();

Help please?

Answer 1

double is not an object, it is a primitive type.

Simply writing (int)b will do the job.

If you really need a Double object, you need to construct one.
