Thread:
A thread is a thread of execution in a program. The Java Virtual Machine
allows an application to have multiple threads of execution running concurrently.
Every thread has a priority. Threads with higher priority are executed in preference
to threads with lower priority. When code running in some thread creates a
new Thread object, the new thread has its priority initially set equal to the priority
of the creating thread. To create a new thread, your program will either
extend Thread or implement the Runnableinterface.
Chat applications considered a multi-user network application, the server is
going to be receiving messages from many users at once. As each message comes
in, it gets added to the transcript on the server. The client applications have to check
back periodically with the server to see if any new messages have arrived. If new
messages are available, the clients will have to ask the server to send the messages
over and then display those new messages in the GUI. The run() method in this class
implements a simple update loop.
