Write the code segments to create a monitor that has the same behavior as a semaphore. Monitor semaphore { //initialization // synchronization condition variable // methods wait ( ) signal ( ) } Solution I assume the code is to be written in Java as no language is specified. The solution is below: public class Monitor_Semaphore { private int count; //initialize public Semaphore (int init) { count = init; } //signal synchronized public void S() { count++; notify(); } //wait synchronized public void W() throws InterruptedException { while (count == 0) wait(); count--; } public void Method1(){ W(); //critical section S(); } }.

1. Write the code segments to create a monitor that has the same behavior as a semaphore.
Monitor semaphore {
//initialization
// synchronization condition variable
// methods
wait ( )
signal ( )
}
Solution
I assume the code is to be written in Java as no language is specified. The solution is below:
public class Monitor_Semaphore {
private int count;
//initialize
public Semaphore (int init)
{
count = init;
}
//signal
synchronized public void S() {
count++;
notify();
}
//wait
synchronized public void W()
throws InterruptedException {
while (count == 0) wait();
count--;
}

2. public void Method1(){
W();
//critical section
S();
}
}
