Usage

From source file:MainClass.java

public static void main(String[] args) {
    ExecutorService application = Executors.newFixedThreadPool(2);

    Buffer sharedLocation = new UnsynchronizedBuffer();

    System.out.println("Action\t\tValue\tProduced\tConsumed");
    System.out.println("------\t\t-----\t--------\t--------\n");

        application.execute(new Consumer(sharedLocation));
    } catch (Exception exception) {
        exception.printStackTrace();
    }

    application.shutdown(); // terminate application when threads end
