Describe the outcome. Why is the order of the execution of the two processes important?
This exercise guides you through experiment with connectionless datagram socket via code sample Example2
Compile the .java classes. Then start Example2ReceiverSender, then Example2SenderReceiver. An example of the commands for running the programs is:
java Example2ReceiverSender localhost 10000 20000 msg1
java Example2SenderReceiver localhost 20000 10000 msg2
The ReceiverSender receives and displays msg2, the SenderReceiver receives and display msg1.
The order of executing the two processes is important because the receiver must be initiated before the senderReceiver sends its message. If the order is reversed, the receiverSender will be blocked indefinitely for data that has already been sent and lost, and the senderReceiver will be blocked on a receive for data that now has no chance of being sent. Thus a deadlock will result.

Which of the following is false?
a. You should not call overridable methods from constructors—when creating a subclass object, this could lead to an overridden method being called before the subclass object is fully initialized. b. It’s OK to any of a class’s methods from its constructors. c. When you construct a subclass object, its constructor first calls one of the direct superclass’s constructors. If the superclass constructor calls an overridable method, the subclass’s version of that method will be called by the superclass constructor. d. It’s acceptable to call a static method from a constructor.
