已知E盘根目录存有一音频文件：mymusic.mp3。 编写程序，要求将该文件数据复制到E盘根目录的mylove.mp3文件中。 说明：用字节流和缓冲流两种办法实现。

使用字节流实现：

import java.io.*;

public class FileCopy {
    public static void main(String[] args) {
        String sourceFilePath = "E:\\mymusic.mp3";
        String targetFilePath = "E:\\mylove.mp3";
        FileInputStream fis = null;
        FileOutputStream fos = null;
        try {
            fis = new FileInputStream(sourceFilePath);
            fos = new FileOutputStream(targetFilePath);
            byte[] buffer = new byte[1024];
            int length;
            while ((length = fis.read(buffer)) > 0) {
                fos.write(buffer, 0, length);
            }
            System.out.println("文件复制成功！");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (fis != null) {
                    fis.close();
                }
                if (fos != null) {
                    fos.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

使用缓冲流实现：

import java.io.*;

public class FileCopy {
    public static void main(String[] args) {
        String sourceFilePath = "E:\\mymusic.mp3";
        String targetFilePath = "E:\\mylove.mp3";
        BufferedInputStream bis = null;
        BufferedOutputStream bos = null;
        try {
            bis = new BufferedInputStream(new FileInputStream(sourceFilePath));
            bos = new BufferedOutputStream(new FileOutputStream(targetFilePath));
            byte[] buffer = new byte[1024];
            int length;
            while ((length = bis.read(buffer)) > 0) {
                bos.write(buffer, 0, length);
            }
            System.out.println("文件复制成功！");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (bis != null) {
                    bis.close();
                }
                if (bos != null) {
                    bos.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
