Homework #3

1. (3 points) Problems 1-3 are accessed and submitted through GOAL; see Gradiance student guide for more information.
   
   
2. (29 points) In problem #3 of HW #1, you were asked to spawn and sychronize 20 processes, each with a single thread of control, to produce the desired output. In this problem, you are asked to write a Java program /home/<logname>/homeworks/hw3/Ping.java as one process with 20 threads of control, and sychronize those threads to print the following (of course, with different thread ids):

   Thread 10: ping
   Thread 11: pong
   Thread 12: ping
   Thread 13: pong
   Thread 14: ping
   Thread 15: pong
   Thread 16: ping
   Thread 17: pong
   Thread 18: ping
   Thread 19: pong
   Thread 20: ping
   Thread 21: pong
   Thread 22: ping
   Thread 23: pong
   Thread 24: ping
   Thread 25: pong
   Thread 25: ping
   Thread 26: pong
   Thread 27: ping
   Thread 28: pong
   

   Each line must be printed by a different thread, and you may not use Java synchronization mechanisms not presented in class. In other words, do not use any Java constructs not presented in class.

   Keep your program to approximately 30 lines and submit a listing of it in class using a2ps at 3:00pm.
