Chapter 16 Exercise 22, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

16.22 (Play, loop, and stop a sound clip) Write a program that meets the following requirements:
■ Get an audio file from the class directory using AudioClip.
■ Place three buttons labeled Play, Loop, and Stop, as shown in Figure 16.46a.
■ If you click the Play button, the audio file is played once. If you click the
Loop button, the audio file keeps playing repeatedly.
If you click the Stop button, the playing stops.
