You are provided with a starter code, which includes the classes: Machine, Person, and the

interfaces Info and Storable. Analyze the code, and then proceed with the following tasks.

Answer the following questions:

a$.$ What is the purpose of the showInfo$()$ method in the Info interface? How is it used in Person and

Machine?

b$.$ What does the store$()$ method represent in the Storable interface?

c$.$ Modify the Person class to also implement Storable. Define what it means to store a person $($e$.$g$.,$

adding them to a database$)$ and implement this in the store$()$ method.

II$.$ Add Method Overloading in the Machine Class:

Task: Overload the start$()$ method in the Machine class to accept different parameters:

$$ start$($String mode$)$: Prints "Machine started in $\{$mode$\}$ mode".

$$ start$($int powerLevel$)$: Prints "Machine started with power level $\{$powerLevel$\}".$

III. Create a New Class Robot That Extends Machine:

Task: Create a Robot class that implements Info. The Robot class should have additional methods:

$$ executeTask$($String task$)$: Prints "Robot is executing $\{$task$\}".$

$$ recharge$()$: Prints "Robot is recharging".

IV$.$ Implement aggregation:

Task: Add a field in the Person class called Machine ownedMachine to represent the machine the person

owns. Modify the greet$()$ method to print out the person's name and their machine's ID by calling the

showInfo$()$ method of Machine.

V$.$ Add a Vehicle Class That Implements Storable:

Task: Create a Vehicle class that implements Storable and adds new functionality:

$$ drive$()$: Prints "Vehicle is being driven".

$$ store$()$: Prints "Vehicle stored in garage".

$$ Demonstrate the usage of Vehicle in the Main class.

VI$.$ Create an Array of Info Objects:

Task: In the Main class, create an array of Info objects, which can include Machine, Person, and Robot.

Loop through the array and call the showInfo$()$ method for each object.

VII. Add Logging to the Machine Class:

Task: Modify the Machine class to include a logOperation$($String operation$)$ method, which prints a log

message for each operation the machine performs $($e$.$g$.,$ starting, stopping$).$ Ensure that this method is

called inside start$(),$ stop$(),$ and store$().$

VIII. Create a ControlPanel Class to Control Multiple Machines:

Task: Create a ControlPanel class that has an ArrayList of Machine objects. Add methods:

$$ addMachine$($Machine m$)$: Adds a machine to the control panel.

$$ startAllMachines$()$: Starts all machines in the list.

$$ stopAllMachines$()$: Stops all machines in the list.
