Why not :

  java.io.File.setReadOnly(boolean mode)

to be able to set it true/false as for a lock-file
mechanism ?

in the java.io.class there is a method to make a file read only.
however this can't be undone. we need a methos like setReadOnly(boolean).
calling this method with a false argument should make the file modifiable.
we also need a method isReadOnly() to test this condition.
thanks

java.io.File class can set read-only attribute on a file
(with setReadOnly() method) but it cannot clear it. If a
Java program encounters a read-only file which it needs
to write or delete, it can only do that using JNI. It's
also unable to undo the effect of previous setReadOnly()
call if it makes one. IMO there should be a method like
setReadOnly(boolean) so that setReadOnly(false) would make
the file writeable or throw an IOException is such operation
is not allowed
