java - If you pass another object a current object's Graphics2D, would it paint on the current object? -

-

for example have class extends jpanel, , want pass it's graphics2d class b. if operations on graphics2d instance in class b paint on class a?

  public void paintcomponent(graphics g){      super.paintcomponent(g);      graphics2d g2d = (graphics2d)g;      ...      b.dosomepainting(g2d);      ...   }

yes. make think otherwise? you're doing delegating painting of graphics2d object of class a class b. it's simple.
