The Producer-Consumer Problem - Part V

In Java, it's idiomatic to use wait and notify, which require acquiring a lock on the object for which those methods are called:

class Shared {
static final int MAX_BUFFER_SIZE = 3;
static Queue<String> buffer = new ArrayDeque<>();
private static final Object lock = new Object();
static void waitUntilNotified() {
try {
synchronized (lock) {
lock.wait();
}
} catch (InterruptedException ex) {
System.out.println(ex);
}
}
static void notifyWaitingThread() {
synchronized (lock) {
lock.notify();
}
}
}
// {...}
public class Main {
public static void main(String args[]) throws Exception {
new Thread(new Producer(), "produce").start();
new Thread(new Consumer(), "consume").start();
}
}
