using Java please solve this problem

Create a program that draws a jack-o-lantern

Open the Jackolantern class. Modify the start method in the .java file so that it displays a reasonably nice-looking jack?o?lantern. The jack-o-lanterns expression should clearly indicate a strong emotion (fear, joy, disgust, etc.).
