Explanation

As soon as you click the "Start" button, the program creates a new thread to call the dangerousLoop() method of remote object. Now, if you click the "Exit" button, the application has the opportunity to notice the event, and process the "Exit" action. Run the program, and see the difference.

The java.lang.Thread Class

public class Thread extends Object implements Runnable

Constructor

• public Thread(Runnable target) - Allocates a new Thread object.

Methods

• public void run() - This method does nothing and returns. Subclasses should override this method.

• public void start() - Registers the thread with the thread scheduler.

There are two ways to create a thread. One is to declare a class to be a subclass of Thread class. The other way to create a thread is to declare a class that implements the Runnable interface.
