plet . And we'll initially take the easiest path from ingredients to cookies before we complic-
ate it.

Example 23-5. Cooklet.java
/** A simple class, just to provide the list of methods that
* users need to provide to be usable in our application.
* Note that the class is abstract so you must subclass it,
* but the methods are non-abstract so you don't have to provide
* dummy versions if you don't need a particular functionality.
*/
public public abstract abstract class class Cooklet Cooklet {

/** The initialization method. The Cookie application will
* call you here (AFTER calling your no-argument constructor)
* to allow you to initialize your code
*/
public

public void void initialize ( ) {

}

/** The work method. The cookie application will call you
* here when it is time for you to start cooking.
*/
public public void void work ( ) {

}

/** The termination method. The cookie application will call you
* here when it is time for you to stop cooking and shut down
* in an orderly fashion.
*/
public public void void terminate ( ) {

}

Now, because we'll be baking, err, making this available to other people, we'll probably
want to cook up a demonstration version too; see Example 23-6 .

Example 23-6. DemoCooklet.java
public public class class DemoCooklet DemoCooklet extends extends Cooklet {

public public void void work () {

System . out . println ( "I am busy baking cookies." );

}
public public void void terminate () {

System . out . println ( "I am shutting down my ovens now." );

}
