Oval creation w/ star inside?

Question

So I'm trying to create a framed oval and put a 5 pointed star inside as part of a class project. The design is more or less up to me- I don't have to put a star in. However, I would like to know how to do this. I am familiar with the creation of lines and ovals, but I am not familiar with the equations required to make the lines grow with the oval as the oval is resized within the program. I can't seem to get the endpoints of the lines to rest perfectly on the frame of the oval; they are either breaching it or not quite long enough. I know how to make the lines grow, just not the correct equation to make them grow properly. If anyone has any experience with this sort of thing, I'd be be quite thankful for their information.

There were some errors:  public void drawStar(Graphics g){
    int centerX=x+width/2;
    int centerY=y+height/2;
    int[] pointsX=new int[5];
    int[] pointsY=new int[5];
    for(int i=0;i<5;i++){ 
      pointsX=(int)(width/2*Math.cos(i*2*Math.PI/5));
pointsY[i]=(int)(height/2*Math.sin(i*2*Math.PI/5));
for(int i=0;i<5;i++){
g.drawLine(centerX+pointsX[i],centerY+pointsY[i],centerX+pointsX[(i+2)%5],centerY+pointsY[(i+2)%5]);}
