This week's book giveaways are in the iOS and Features new in Java 8 forums. We're giving away four copies each of Barcodes with iOS: Bringing together the digital and physical worlds and Core Java for the Impatient and have the authors on-line! See this thread and this one for details.
What is the logic behind the synchronization on the letter object? Can you put just any object inside the synchronization parentheses just to satisfy the requirement of synchronizing a block of code? I'm trying to learn the synchronization concepts of threads and I'm looking for a clear cut explanation on this concept.
Yes, you can practically use any object as the synchronization lock... but there is a reason why the stringbuffer was chosen. It is the same instance with all three threads, and synchronization was done to prevent the threads from stepping on each other.
So if you use any other object, you have to make sure that the three threads are using the same instance / object.
