One benefit of the New AWT event model is flexibility. In the old model we were forced to write code hard for our program. But the new model we can invoke to add and delete event actions in a single method. The following example demonstrates this: : Dynamicevents.java//The new Java 1.1 event model allows to//change event behavior dynamically. Also//Demonstrates multiple actions for an event. Import
