Removing Variables

Question

my work says to Remove the r, c and e variables from this how would I do this

Rectangle  r = new Rectangle(10 * iFrame, 10 * iFrame, 50, 50); r.draw(gcw);
  
Circle c= new Circle(200, 300 - iFrame*5, 100); c.draw(gcw);
  
Ellipse e = new Ellipse(150, 300, 90 + iFrame, 160); e.draw(gcw);

Answer 1

You can invoke draw(..) on the object returned by the constructor without assigning it to a variable. You are still creating an object - you just aren't assigning it to a variable so you can access it elsewhere.

new Rectangle(10 * iFrame, 10 * iFrame, 50, 50).draw(gcw);
new Circle(200, 300 - iFrame*5, 100).draw(gcw);
new Ellipse(150, 300, 90 + iFrame, 160).draw(gcw);
