We'll cover the following...

Monitor Implementation

We can also implement the bounded buffer using the Monitor class. In fact, using the Monitor class saves us from busy-waiting, as a blocked thread can relinquish the monitor until it gets signaled.

Let's implement the enqueue() method first. We'll define the entire method as a critical section as we manipulate shared data-structures within it. Below is the implementation:

Press + to interact
public void enqueue(int data)
{
    Monitor.Enter(items);
    while (currentSize == maxSize)
    {
        Monitor.Wait(items);
    }
    if (tail == maxSize) tail = 0;
    items[tail] = data;
    currentSize++;
    tail++;
    Monitor.PulseAll(items);
    Monitor.Exit(items);
}

The enqueue() implementation should look eerily similar to the one which ...
