Introduction
The Java.io.FilePermission class represents access to a file or directory.It consists of a pathname and a set of actions valid for that pathname. Following are the important points about FilePermission −
- The actions to be granted are passed to the constructor in a string containing a list of one or more comma-separated keywords. The possible keywords are “read”, “write”, “execute”, and “delete”.
- Code can always read a file from the same directory it’s in (or a subdirectory of that directory); it does not need explicit permission to do so.
