Java实现的音乐播放器

由于疫情的原因在家闲着，然后就写了个播放器来练练手。

下面先放效果图：

          

 

       

          

 

 

 

这里主要实现了歌曲的播放，上一曲，下一曲，获取歌曲的时间，播放歌曲进度条滚动，获取歌曲的海报，能自动播放（顺序播放，单曲循环播放，随机播放),可以导入外部歌曲，可以定时关闭音乐并退出，可以设置两个模式（白天和黑夜）。还有一个没有完成的功能，收藏喜欢歌曲的功能，本来想通过数据库保存喜欢歌曲的路径来实现这个功能的，然后太懒了，不想写了）。

用以下代码的时候，需要导入几个java包，这里是这几个包的下载链接，链接：https://pan.baidu.com/s/1UL0IRHNK8V54lirS3SUo-g 
提取码：zkc0

然后把，下面展示代码，代码大多有注释，这里就不多解析了：
