java解析lrc文件代码
lrc可以通过如下util工具类进行转换，如果想知道结果是否读取的有问题，可以直接用记事本打开lrc文件的，之后和输出结果比对一下就行。

求教，急用！JAVA按歌词文件的时间标签从小到大排列内容，然后最好能给我做个方法，让我直接调用，排
你好，这是你要的方法，直接输入路径调用就可以了，输出结果是sorted-加原文件名
/**
* 根据路径和编码 重新排列歌词中的文件，转换后的文件是“sorted-原文件”
*
* @param source 原文件
*/
public static void sortLyric(String source) {
try {
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(source), "UTF-8"));
ListString lines = new ArrayListString();
String line;
while ((line = br.readLine()) != null) {
lines.add(line);
}
br.close();
Collections.sort(lines);
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("sorted-" + source, false), "UTF-8"));
for (String everyLine : lines) {
bw.write(everyLine);
bw.newLine();
bw.flush();
}
bw.close();
} catch (Exception e) {
e.printStackTrace();
}

在java中怎么从键盘输入一段歌词以空格用split()分割
public static void main(String[] args) {
// TODO 自动生成的方法存根
Scanner sc = new Scanner(System.in);
System.out.println("请输入歌词:");
String s = sc.nextLine();
String[] x = s.split(" ");
for(int i = 0;ix.length;i++){
System.out.println(x[i]);
}
}
JAVA截取字符串(截取歌词)
把歌词存在一个叫 geci.txt 的文本中 放在D盘根目录
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
public class SaveSong {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
BufferedReader br = null;
String lineContent = "";
String[] s = new String[100];
int i = 0;
try {
br = new BufferedReader(new FileReader("D:\\geci.txt"));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
while ((lineContent = br.readLine()) != null) {
System.out.println(lineContent);
s[i]= lineContent;
i++;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
用java写程序 显示一首歌的一段歌词 并标注和声部分
很简单啊，创建一个类，再建一个方法，在里面创建一个String类型变量，里面放入你想放入的歌词，标注也可以加在里面。
java 正则表达式 匹配[00:00.00]或者[00:00]这两种歌词时间格式的正则表达式
下面的代码就是你想要的:
public static void main(String[] args) {
String regx1="\\[\\d{2}:\\d{2}.\\d{2}\\]";
String regx2="\\[\\d{2}:\\d{2}\\]";
Pattern p = Pattern.compile(regx1);
String str = "[124:00.00]";
Matcher m = p.matcher(str);
if(!m.matches()){
p = Pattern.compile(regx2);
m = p.matcher(str);
if(!m.matches()){
System.out.println("输入格式不符合要求!");
}else{
System.out.println("输入格式正确! 匹配格式为:"+"[00:00]");
}
}else{
System.out.println("输入格式正确! 匹配格式为:"+"[00:00.00]");
}
}
