Answer 5

R Yuvaraj there are wrong spellings
g.draw RoundedRect(20,20,140,100,10,10);
should be
g.drawRoundRect(20,20,140,100,10,10);

and

g.filledOval(65,43,50,50)
should be
g.fillOval(65,43,50,50)

and as others suggested, don't use applet and just modify this tutorial:

I successfully compiled and ran the codes below on my laptop. The second version used Graphics2D for anti-aliasing.

Unfortunately Sololearn cannot display them.

I trust you know how to compile and run a java class and you have the necessary sdk installed.
