Not all platforms have the ability to identify an "executable"
attribute of a file.

: Tell us non-Unix types what this method does. Perhaps the reason is
: it would only have meaning on Unix platforms.

It could mean the system knows what to do with the file when the user
changes the CSD to its directory and types its name in at the prompt.

Not all platforms can print. Not all platforms have colour screens.

If not all platforms support something, that is not sufficient reason
for Java not to support it.

Windows has a flag for marking executable files (Properties>
Security>Advanced).

Unix does also - I guess that covers Linux, Solaris and OSX as well.

attribute of a file.

windows itself does not have such an attribute bit. What determines if
something is executable is if there is a hook for the extension in the
registry. For example you can make .html executable in that clicking
an HTML file will execute the html by starting a browser and rendering
it.
