How to cast double to int??

[muraj]

Hi I'm trying to draw a line in java using g.drawLine

g.drawLine (int, int, int, int) || x1, y1, x2, y2

im trying to draw this :
g.drawLine (xCenter + 200 * Math.cos(2 * Math.PI * 3 / 7), yCenter + 200 * Math.sin(2 * Math.PI * 3 / 7), 70 ,336);

but that above is (double, double, int, int)

I made a cast for Math.PI like :
int pi = (int) Math.PI;
this worked

I then tried to do
int cos = (int) Math.cos;
this did not work

so i still get a (double, double, int, int) and g.drawLine wont compile that.
any ideas on how to fix? thanks!!!!

note xCenter and yCenter were both suppose to equal 250

In this case you should cast the result of the evaluation of "xCenter + 200 * Math.cos(2 * Math.PI * 3 / 7)" or "yCenter + 200 * Math.sin(2 * Math.PI * 3 / 7)":

g.drawLine ((int)(xCenter + 200 * Math.cos(2 * Math.PI * 3 / 7)),(int)(yCenter + 200 * Math.sin(2 * Math.PI * 3 / 7)), 70 ,336);

That worked, although it didn't draw anything
