Write a Java application or applet program that (1) plays a sound file; (2) displays an image moving from the top to the bottom of the panel, and if the image reaches the bottom of the panel it will be randomly and vertically bounced back. This process will run forever unless you terminate the program; and (3) displays a randomly colored circle moving from the top to the bottom of the panel, and if the circle reaches the bottom of the panel it will be randomly and vertically bounced back. This process will run forever unless you terminate the program. A sample run of the program is shown in Appendix 1.
