Survey Summary

Permission issues:Your JDK directory is on drive C, and the current user has no write permission;
Solution:1. modify directory permissions. It is best to use the Java directory 2. Because JDK environment variables are already available, change to other partitions and execute arbitrary directories.

Thinking: I found that the attributes of all directories on the computer drive C are read-only and I have never paid attention to them before (Note: I have logged on with non-administrator permissions ). In other words, except Windows folders may be protected, other folders should not be read-only.

I. Want to know why it is read-only?

2. Manually change the directory properties to remove read-only data. In addition to permission modification, is there any other way to modify or remove this attribute?

Anyone who knows about Windows permission attributes can give me some help!
