Explanation:
Following are the Semaphores:
Customers: Counts waiting customers;
Barbers: Number of idle barbers (0 or 1)
mutex: Used for mutual exclusion.
Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves
Shared data variable:
count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.
// shared data
semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;
int count_cust= 0;
void barber() {
while(true) { //shop is always open
wait(customers); //sleep when there are no waiting customers
wait(mutex); //mutex for accessing customers1
count_cust= count_cust-1; //customer left
signal(barbers);
signal(mutex);
cut_hair();
}
}
void customer() {
wait(mutex); //mutex for accessing count_cust
if (count_cust< n) {
count_cust= count_cust+1; //new customer
signal(customers); signal(mutex);
wait(barbers); //wait for available barbers get_haircut();
}
else { //do nothing (leave) when all chairs are used. signal(mutex);
}
}
cut_hair(){ waiting(cutting);
}
get_haircut(){
get hair cut for some time; signal(cutting);
}
Answer: Cyber warfare is a real threat since being able to hack another computer especially a countries computer with lots of info in their weaknesses can lead to their downfall. Since they can even possibly if their skilled enough hack their entire data base system and leak it to the public and that wouldn't be good for them not in a single possible way. That's the reason it's dangerous not only that but also because they can access their servers; which can let them access anything online from the whole country including banking information military info which can let them know which area there gonna go to next equipment there gonna bring and where they're gonna launch missiles, bombs, even nukes if they decide to launch one. And being able to hijack the computer that launches the nukes can make the hacker launch the nuke to a different place or launch the nuke on the country trying to launch the nuke.
Explanation:
Answer:
The main method should simply terminate if the FileNotFoundException occurs.
Explanation:
Considering the full code snippet
snippet:public static void main(String[] args) throws FileNotFoundException
public static void main(String[])
represent the entry point method to a java main method
The addition of
throws FileNotFoundException
widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.
So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.
By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method
This is required by the compiler to terminate the program if the FileNotFoundException occurs.
