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
1 One can implement threads in two ways:
  • First, by subclassing the Thread class
  • Second, by implementing the Runnable interface
2 A class that implements the Runnable interface (including the Thread class itself) must implement the run() method containing the "body" of the thread.
3 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.)
