最快的文件复制方法

    private static void customBufferStreamCopy(File source, File target) {        InputStream fis = null;        OutputStream fos = null;        try {            fis = new FileInputStream(source);            fos = new FileOutputStream(target);            byte[] buf = new byte[4096];            int i;            while ((i = fis.read(buf)) != -1) {                fos.write(buf, 0, i);            }        }        catch (Exception e) {            e.printStackTrace();        } finally {            close(fis);            close(fos);        }    }
