Exercise $4$

Create the Atm class. This class has the attribute money that gets its value as an argument from the constructor.

money $-$ double that represents the amount of money in the account

This attribute should have a getter method, but not a setter. The class should have two method, deposit and withdrawal. The deposit method should contain data validation to check if the amount of money deposited is positive. Print a message if the data validation fails. The withdrawal method should check the data to see if there is enough money to withdraw and that the amount is positive. Print a message to the user if data validation fails.

Expected Output

Verify that your program works for each of the following scenarios.

Scenario $1-$ Deposit and withdraw valid amounts of money

$//$add code below this line

Atm myAtm $=$ new Atm$(1000)$;

myAtm.deposit$(50)$;

System.out.println$($myAtm$.$getMoney$())$;

myAtm.withdraw$(925)$;

System.out.println$($myAtm$.$getMoney$())$;

$//$add code above this line

This code should produce the following output:

$1050\mathrm{.}0$

$125\mathrm{.}0$

Try it

Scenario $2-$ Deposit amount is not positive

$//$add code below this line

Atm myAtm $=$ new Atm$(1000)$;

myAtm.deposit$(-50)$;

System.out.println$($myAtm$.$getMoney$())$;

$//$add coExercise $4$

Scenario $2-$ Deposit amount is not positive

$//$add code below this line Atm myAtm $=$ new Atm$(1000)$; myAtm.deposit$(-50)$; System.out.println$($myAtm$.$getMoney$())$; $//$add code above this line

This code should produce the following output:

You cannot deposit a negative amount of money. $1000\mathrm{.}0$

Try it

Scenario $3-$ Withdrawal amount is too large

$//$add code below this line Atm myAtm $=$ new Atm$(1000)$; myAtm.withdraw$(5000)$; System.out.println$($myAtm$.$getMoney$())$; $//$add code above this line

This code should produce the following output:

You do not have enough funds to withdraw that amount. $1000\mathrm{.}0$

Try it

Scenario $4-$ Withdrawal amount is not positive

$//$add code below this line Atm myAtm $=$ new Atm$(1000)$; myAtm.withdraw$(-50)$; System.out.println$($myAtm$.$getMoney$())$; $//$add code above this line

This code should produce the following output:

You cannot withdraw a negative amount of money. $1000\mathrm{.}0$
