Hi! question again.

I wanna know how to convert double to int? From my work i read data from file to double and i wanna use this double to deal with degree in pie chart but i cannot use double in my pie chart. looklike only int can be use overthere.

From program below, degree2[n] is double
but i need to convert degree2[n] to int to use with fillArc.

Any advice please?

public void paint(Graphics g)
{
double degree2[] = new double[datas.size()];

for (int n=0; n<datas.size(); n++ )
{
String string = (String) datas.elementAt(n);
double num = TButils.str2double(string);
degree2[n] = Math.round(num*360/all);
System.out.print(degree2[n]);
}
a=degree2[3]; ** Error here**
super.paint(g);
g.setColor(Color.red);
g.drawOval(75,75,150,150);
g.fill Arc(75,75,150,150,0,a);
}


thanawat
