A convenience method to set the owner's read permission for this abstract pathname. On some platforms it may be possible to start the Java virtual machine with special privileges that allow it to read files that are marked as unreadable.

An invocation of this method of the form file.setReadable(arg) behaves in exactly the same way as the invocation


     file.setReadable(arg, true)

Parameters:

readable If true, sets the access permission to allow read operations; if false to disallow read operations

Returns: true if and only if the operation succeeded. The operation will fail if the user does not have permission to change the access permissions of this abstract pathname. If readable is false and the underlying file system does not implement a read permission, then the operation will fail.

Exceptions:

SecurityException If a security manager exists and its java.lang.SecurityManager.checkWrite(java.lang.String) method denies write access to the file
