Foil 4 How to Use Threads

From Java Tutorial 98- 4: Multi-Treading, Useful Java Classes, I/O and Networking NAVO Tutorial -- Sept 23 1998. by Geoffrey C. Fox, Nancy McCracken
API to show relationship between Thread class and Runnable interface for Foil 4
One can implement threads in two ways:
  • First, by subclassing the Thread class
  • Second, by implementing the Runnable interface
A class that implements the Runnable interface (including the Thread class itself) must implement the run() method containing the "body" of the thread.
The Runnable interface makes it possible for an applet to utilize threads. (Remember, an applet extends the Applet class and so cannot multiply inherit from the Thread class.)
