Assignment $7$ A: Finite State Automata.

In computer architecture $($a class you might take in the future$)$ we teach a concept called $$Finite

State Automata$.$ Also known as $$State Machines$,$ these models show different states of a

system and how you can move from one to other. We are going to simulate one using objects.

First, review the following diagram:

You will create a FSA class with one attribute: int state. The valid states are shown in the

diagram above. It should also have the following methods:

$$ constructor: Takes in one integer for the state attribute. If the state is not one of the values

shown, it should be initialized to $0$ and the constructor should print out $$This is an invalid

state. Starting at state $0$

$01$

$32$

$$ int goToNextState$()$: Takes in no parameters and advances the state variable to the next

state based on the diagram above. It should then return the state variable. It should not

print anything.

$$ bool$/$Boolean end$()$: Takes in no parameters. It returns TRUE if the state is currently $3,$

and returns FALSE otherwise.

You will then create a separate class $($and file$),$ Assignment$7$A$.$ In its main method, you

should do the following:

$$ Prompt the user to enter a state

$$ Create a new FSA object using the constructor

$$ Create a loop and prompt the user with two choices

$$Go to next state$$ This should call the goToNextState$()$ function on the FSA

object and print the current state based on the value returned from the

function

$$End$$ This should call the end$()$ function. If the returned value is TRUE, end

the loop and program. Otherwise, tell the user they can only end the program

at state $3.$

Sample Output:

$[$Finite State Automata$]$

What state do you want to start at$?1$

What will you do$?$

$>$Go to next state

$>$End

Go to next state

You$$re now at state $2.$

What will you do$?$

$>$Go to next state

$>$End

END

You can$$t stop here; you can only stop at state $3.$

What will you do$?$

$>$Go to next state

$>$End

Stop

$[$Invalid command!$]$

What will you do$?$

$>$Go to next state

$>$End

Go to NEXT state

You$$re now at state $3.$

What will you do$?$

$>$Go to next state

$>$End

End

The FSA has shut down.
