Recall that to solve a readers/writers problem (Operating Systems), create a multi-thread program to simulate the problem. The following conditions must be satisfied:

1. Any number of readers may simultaneously read the file.

2. Only one writer at a time may write to the file.

3. If a writer is writing to the file, no reader may read it.

Please use semaphore to implement mutual exclusion. Please also create some-sort of GUI Interface to choose between Readers having priority or Writers having priority. In Java
