本文實(shí)例為大家分享了java音樂(lè)播放器的具體代碼，供大家參考，具體內(nèi)容如下
這個(gè)是源碼結(jié)構(gòu)介紹
這個(gè)是界面，有點(diǎn)簡(jiǎn)陋，見笑了，但是基本上的東西都有了，沒辦法，沒有美工的程序?qū)懙慕缑?/p>
直接上源代碼Player.java

剩下的代碼在后面附件上有，現(xiàn)在主要是有幾個(gè)小問(wèn)題，第一，我還沒有找到獲取音樂(lè)文件具體信息比較好的辦法，所以每一首暫時(shí)還沒有歌手，作曲的信息，第二界面有點(diǎn)難看，見諒了，第三個(gè)是打包成jar文件會(huì)有路徑問(wèn)題，暫時(shí)還沒辦法解決，我是直接在myeclipse上運(yùn)行，一切正常，就是打包有點(diǎn)小問(wèn)題
暫時(shí)先說(shuō)這些了，這個(gè)是我業(yè)余時(shí)間的項(xiàng)目，有什么不足的，大家都可以提出來(lái)。
