楼主新人,很多都不懂,只有一些思路,但不知如何实现 希望能给些意见
思路一:
看到时间戳有规律,都是以"00:"开头,共有12+5+12共29个字符(空格和符号都算上),想到用String类的方法,文本转为String,找到"00:",向后取26个字符,去除,但好像只有split能用,正则表达式不太懂,无法下手
思路二:
想到bufferedReader.readLine()方法.既然是一行一行读取,独到包含有"00:"这一行时不把它写入文本不就行了?
根据思路写下如下代码:
public class ReadUtils {
public static void main(String[] args) {
try {
String encoding = "UTF-8"; // 字符编码(可解决中文乱码问题 )
File file = new File("f:/作业/House_Of_Cards_S01E01.lrc");
if (file.isFile() && file.exists()) {
InputStreamReader read = new InputStreamReader(
new FileInputStream(file), encoding);
BufferedReader bufferedReader = new BufferedReader(read);
FileWriter fw = new FileWriter("buf_copy.txt");
BufferedWriter bufw = new BufferedWriter(fw);
String lineTXT=null;
while(((lineTXT = bufferedReader.readLine()).contains("00:"))){
bufw.write(lineTXT);
String str= lineTXT.toString().trim();
System.out.println(str);
}
read.close();
bufw.close();
}
} catch (Exception e) {
System.out.println("读取文件内容操作出错");
e.printStackTrace();
}
}
}
结果控制台和txt文件都只有"1",不明白为什么不循环 while(((lineTXT = bufferedReader.readLine()).contains("00:")))这是自己瞎写的,没有编译错误,可我看不出啥错,为什么不向下循环?
为什么while ((lineTXT = bufferedReader.readLine()) != null)这个就能循环呢?
求指点,可能都是小错误,小知识点,轻拍
------解决方案--------------------
没看清要求，你把输出的那个位置改成*.txt就好了
