JAVA 添加背景音乐，网上有很多，但是要么不能用，要么报错，这个我试过可以用。

public class musicStuff {
	void playMusic(String musicLocation)
	{
		try
		{
			File musicPath = new File(musicLocation);
			
			if(musicPath.exists())
			{
				AudioInputStream audioInput = AudioSystem.getAudioInputStream(musicPath);
				Clip clip = AudioSystem.getClip();
				clip.open(audioInput);
				clip.start();
				clip.loop(Clip.LOOP_CONTINUOUSLY);
			}
			else
			{
				
			}
		}
		catch(Exception ex)
		{
			ex.printStackTrace();
		}
	}

}

主类中加入

		String filepath = "giao.wav";
		musicStuff musicObject = new musicStuff();
		musicObject.playMusic(filepath);
