Behaviours 

When concerning the job done by agents it is basically carried out within “behaviours”.  Behaviours are created by extending the jade.core.behaviours.Behaviour class. If you want to make the agent execute a task then you should create an instance of the corresponding Behaviour subclass and call the addBehaviour() method of the Agent class. Each Behaviour subclass must implement following methods.

•   public void action():  what the behaviour actually does
•    public boolean done(): Whether the behaviour is finished or not

 There are some Behaviour types as listed below.

•  “One shot” behaviours.

The class is jade.core.behaviours.OneShotBehaviour . This completes immediately and the action() method is executed only once. Their done() method simply returns true.

• “Cyclic” behaviours.

The class is jade.core.behaviours.CyclicBehaviour. This never completes and their action() method executes the same operation each time it is invoked. Their done() method simply returns false.

• “Complex” behaviours.

This completes when a given condition is met.  Embed a state and execute in their action() method, different operation depending on their state.
