Modified code:

“Account.java”:

    //Private variable

    private double balance;

    //Define a constructor

    public Account()

    //Function to get balance

    public double getBalance()

    {

        //Return the amount

        return balance;

        //Else

        Else

            //return -1;

            //Throw an exception

            throw new NegativeAmountException();

        //Return the balance

        return balance;

        //Else

        else

            //Calculate the balance
