使用java将.mp3文件从一个文件夹复制到另一个文件夹

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

File sourceFile = new File("源文件夹路径/文件名.mp3");
File destFile = new File("目标文件夹路径/文件名.mp3");

FileInputStream fis = null;
FileOutputStream fos = null;
try {
    fis = new FileInputStream(sourceFile);
    fos = new FileOutputStream(destFile);

    byte[] buffer = new byte[1024];
    int length;

    while ((length = fis.read(buffer)) > 0) {
        fos.write(buffer, 0, length);
    }

    fis.close();
    fos.close();
} catch (IOException e) {
    e.printStackTrace();
}
