How to draw a hexagon in java

This should be easy, but I'm having a difficult time finding the answer. I'm trying to draw a regular hexagon.

How do I draw a line 100 pixels long, then draw another line that is 100 pixels long at a 120 degree angle from where the first line ended?

If it's not much harder, what is the best way to draw an entire hexagon like this given the absolute center?

try the following:

    Polygon getHexagon(int x, int y, int h)
    {
        Polygon hexagon = new Polygon();

        double a;
        for (int i=0; i < 7; i++)
        {
           double a = Math.PI / 3.0 * i;
           hexagon.addPoint((int)(Math.round(x + Math.sin(a) * h)), (int)(Math.round(y + Math.cos(a) * h)));
        }
        return hexagon;
    }
