Introduction to Threads
A thread is a single sequential flow of control within a process.
If a process has more than one thread, then each thread executes concurrently.
Any Java applet that has extensive execution or loops to repaint the window must run as a concurrent thread with the browser window.
To make an applet with a thread:
- Change your applet definition to add "implements Runnable", the interface for threads.
- Include an instance variable for the thread of your applet.
- Have a start() method that creates a thread and starts it running and a stop() method which stops it running.
- Implement a run() method containing the body of your applet code.
