That is not the same thing. A file handle must be closed with the close
command. The close command is like a destructor for an object. Java
objects have no destructor, so there is no functional mapping.
A file handle in Tcl is just a hash table mapping from the
string name to the file descriptor.
"file0" -> int or whatever
