Recall that we used the example of a bunch of superheroes in the last session on Creational design patterns. Let's take the same example here and try to create a Bridge pattern considering the following scenario:

Let$$s consider $2$ superheroes for now: The Magician and Avon The Slayer. There are $3$ functions that will be done by these two $-$ Appear, Attack and Retreat. There will be $2$ types of actions for each of the superheroes $-$ AvonAction and TheMagicianAction.

There will be $3$ pre$-$actions: onActivate, apply and onDeactivate. These $3$ pre$-$actions will be defined for the Superhero Action class. These $3$ pre$-$actions will define when the superhero will perfom his$/$her action.

You can refer the following steps to create the solution for the problem:

$1.$ Create an interface which declares the $3$ superhero actions

$2.$ Create $2$ classes: The Magician and Avon the Slayer which defines all $3$ actions declared in the Revenger interface

$3.$ Create the interface class for the Superhero Action which will declare the $3$ pre$-$actions

$4.$ Create the implementation of the $3$ pre$-$actions for both the superheroes

$5.$ Write the client code for the $3$ actions

Create $2$ hierarchies of the superheroes and the impact of their actions, and subsequently make appropriate function calls such that the console output looks like this$-$

The Magician receives a call from the victim.

The Magician has appeared from nowhere! $($on calling the appear function$/$method$)$

The Magician is in action. $($on calling the appear function$/$method which calls the onActivate function$)$

The Magician flies and punches the villain in the face. $($on calling the attack function$/$method$)$

The punch from The Magician goes through the face of the villain and paralyzes the villain. $($on calling the attack function$/$method which calls the apply function$)$

The Magician disappears. $($on calling the retreat function$/$method$)$

The Magician prepares for her next attack. $($on calling the retreat function$/$method which calls the onDeactivate function$)$

Avon the Slayer is being called.

Avon The Slayer has appeared from nowhere! $($on calling the appear function$/$method$)$

Avon The Slayer is in action. $($on calling the appear function$/$method which calls the onActivate function$)$

Avon the Slayer swings his sword swiftly to attack the villain. $($on calling the attack function$/$method$)$

Avon's sword is deadly and cuts of the villain's arm. $($on calling the attack function$/$method which calls the apply function$)$

Avon The Slayer disappears. $($on calling the retreat function$/$method$)$

Avon the Slayer prepares for his next attack. $($on calling the retreat function$/$method which calls the onDeactivate function$)$

Note: The action of the superhero and the impact of the action are to be separated using the concepts of the Bridge pattern.
