1. For the following program, draw a stack diagram showing the state of the program just before distance returns. Include all variables and parameters and the objects those variables refer to.

2. What is the output of this program?

public static double distance(Point p1, Point p2) {

int dx = p1.x - p2.x;

int dy = p1.y - p2.y;

return Math.sqrt(dx*dx + dy*dy); }

public static Point findCenter(Rectangle box) {

int x = box.x + box.width/2;

int y = box.y + box.height/2;

return new Point(x, y); }

public static void main(String[] args) {

Point pnt = new Point(5, 8);

Rectangle rect = new Rectangle(0, 2, 4, 4);

Point center = findCenter(rect);

double dist = distance(center, pnt);

System.out.println(dist); }
