Threads:

• extends Thread :
  • Thread.sleep(ms)
  • Lunch in main:
    • ThreadClassName objName = new ThreadClassName(...)
    • objName.start()
• implements Runnable :
  • Lunch in main:
    • ThreadClassName objName = new ThreadClassName(...)
    • Thread thrd1 = new Thread(objName,"name1")
    • Thread thrd2 = new Thread(objName,"name2")
  • Thread.currentTread.getName() # get thread name
• synchronized(this), wait, notifyAll (watch BlockingList)
  • You can create 2 runnables one for producer and the other for consumer, both they have a while loop to the call function (put -> prod and take -> cons) of the same instance from Blocking List

• UDP (unicat/multicast)
