I think this is an easy one.  In the Java Language, how do I determine
if I have permission to execute a file (execute permissions for the
user the program is running under) without acutally running that
program (shell script/Unix or batch file/Windows)?

Answer

There is no answer at this time.

Hi there Dwight.

File permissions are a system specific concept, and as such, Java
doesn't have any inbuilt functionality for doing this.

If you knew that you were on a Unix system, you could use the Runtime
class to execute chmod or the like. See here for more:
