问题描述

如何为使用Java InputStream API创建和写入的文件设置只读访问权限.

How to set read-only access for a file that's been created and written using java InputStream API.

推荐答案

在我看来，最好先检查文件是否已创建或存在，然后再设置只读标志.

In my opinion, it's good to check whether the file has been created or exists first and then set the read only flag.

    File file = new File("C:/path/file.txt");
    if (file.exists()) {
        file.setReadOnly();
    } else {
        System.out.println("File does not exists.");
    }
