JavaFX example of a MP3 player

This is a simple example of a mp3 player created with JavaFX. It has a button to open and play the track, pause, resume and stop buttons with their respective functionalities. To play the music we use MediaPlayer class -> The MediaPlayer class provides the controls for playing media.

MediaPlayer provides the pause(), play(), stop() and seek() controls as well as the rate and autoPlay properties which apply to all types of media. It also provides the balance, mute, and volume properties which control audio playback characteristics.
