Java 文件复制函数

 Java 文件复制函数：一个参数是原文件，一个是目的文件，简单实用

    public static void copyFile(String source, String destination) {
        try {
            FileInputStream fis = new FileInputStream(source);
            FileOutputStream fos = new FileOutputStream(destination);
            byte[] buffer = new byte[1024];
            int length;
            while ((length = fis.read(buffer)) > 0) {
                fos.write(buffer, 0, length);
            }
            fis.close();
            fos.close();
            System.out.println("File copied successfully!!");
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }
}
