java音乐剪辑代码（只能剪辑从开始到最后的部分，也可以中间截取，加个计数器就行了）

import java.io.*;

public class MusicCut {
public static void main(String[] args) throws IOException {
FileInputStream fis = new FileInputStream(“d://sss.txt”);
File sss = new File(“d://sss.txt”);
FileOutputStream fos = new FileOutputStream(“d://ss.txt” );
File ss = new File(“d://ss.txt”);
System.out.println((double) ((double)8/(double)9));
int len;
while ((len = fis.read()) != -1) {
fos.write(len);
if (((double)ss.length() / (double)sss.length()) >= 0.5) {
System.out.println(((double)ss.length() / (double)sss.length()));
System.out.println(“ss的长度：”+ss.length());
System.out.println(“sss的长度：”+sss.length());
break;
}

    }

    fos.close();
    fis.close();


}

}
