Thread: Unisex batroom

I am having trouble with the Unisex problem in java using thread synchronization. I have four classes the PCB class has all of the methods in it that will be used by the other classes. Then the FemaleThread and MaleThread classes which are similar there are suppose to extend thread, have the PCB member variables ,as well as a construtor and run method that loops 10 times then sleeps random amount of time then enters the bathroom when it is time and then sleeps again, simulating using the bathroom and then finally exits the bathroom. Each thread is suppose to visit the bathroom 10 times and have 5 threads for each Male and Female and only males or females can be in the bathroom at any one time. I am having trouble with the structure of this code. I believe I got the logic behind it but I just have things in the wrong place. Any help that might be out there would be greatly appreciated. I have attached the classes and they are seperated with the file name.
