WebJul 6, 2016 · As of Java 5, write access to a volatile variable will also update non-volatile variables which were modified by the same thread. This can also be used to update values within a reference variable, e.g. for a volatile variable person. In this case you must use a temporary variable person and use the setter to initialize the variable and then assign the … WebFeb 3, 2024 · The solution is to use Stream I/O which was introduced with the Fortran 2003 Standard and is now widely implemented. Stream I/O, as with sequential and direct-access I/O comes in two flavours: formatted and unformatted. It is the unformatted form which provides the more powerful facilities, so I will describe this first.
