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]");

}

}
