java写一个音乐播放程序，同时显示歌词
java写一个音乐播放程序，同时显示歌词
总的来说分为两部分：1.音乐播放 2.显示歌词（这里介绍一个好理解的算法，就不进行优化了）
一、音乐播放（这里我们在网上先下载一个wav文件来播放）
这里我们使用eclipse软件进行编程。
- 首先，我们需要知道JDK原生只支持音频格式为*.wav *.au *.aiff 的音乐
- 如果我们不希望使用JDK原生支持，就需要自己使用jar包（下面代码我是使用JDK原生支持的播放器来写的）
- 注意一下我的两个资源，一个是邓紫棋泡沫的歌曲.wav，一个是邓紫棋画的歌.lrc（因为实在没找到邓紫棋画的wav文件就先对付上了…）
// JDK自带音乐播放无需导包
public static void MusicPlayer() {
try {
AudioPlayer.player.start(new FileInputStream(new File("./music/邓紫棋 - Paomo.wav")));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}二、显示歌词（这里我们先解析已有的lrc歌词文件，存放到data里面再进行操作）
public class Demo1 {
// 定义两个存放分钟和秒的数组
private static double[] d1 = new double[55];
private static double[] d2 = new double[55];
public static void main(String[] args) throws IOException {
// 读取lrc文件并转编码到 data4中
BufferedReader reader = null;
try {
reader = new BufferedReader(new InputStreamReader(new FileInputStream("./data/画-邓紫棋.lrc"), "GBK"));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BufferedWriter writer = null;
try {
writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("./data/data4.txt"), "UTF-8"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (String i = reader.readLine(); i != null; i = reader.readLine()) {
writer.write(i);
writer.newLine();
}
reader.close();
writer.close();
// 获取秒数组 d1[]
BufferedReader reader2 = new BufferedReader(new InputStreamReader(new FileInputStream("./data/data4.txt")));
int countLine = 0;
while ((reader2.readLine()) != null) {
countLine++;
if (countLine <= 4)
continue;
for (int i = 0; i < d1.length; i++) {
d1[i] = Double.parseDouble(reader2.readLine().substring(4, 9));
// System.out.println(d1[i]);
}
}
reader2.close();
// 获取分数组d2[]
BufferedReader reader3 = new BufferedReader(new InputStreamReader(new FileInputStream("./data/data4.txt")));
int countLine2 = 0;
while ((reader3.readLine()) != null) {
countLine2++;
if (countLine2 <= 4)
continue;
for (int i = 0; i < d2.length; i++) {
d2[i] = Double.parseDouble(reader3.readLine().substring(2, 3));
// System.out.println(d2[i]);
}
}
reader3.close();
// 歌词根据时间差输出到控制面板
BufferedReader reader4 = new BufferedReader(new InputStreamReader(new FileInputStream("./data/data4.txt")));
int countLine3 = 0;
while ((reader4.readLine()) != null) {
countLine3++;
if (countLine3 <= 4)
continue;
// 延迟判断
for (int i = 0; i < 55; i++) {
// 歌词
System.out.println(reader4.readLine().substring(10));
//时间差
double num1 = d1[i] * 1000 + d2[i] * 60 * 1000;
double num2 = d1[i + 1] * 1000 + d2[i + 1] * 60 * 1000;
long num3 = Math.round(num2 - num1);
try {
Thread.sleep(num3);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
reader4.close();
}
