When attempting this exercise, you should refer to the following Java documentation for class BankAccount:

Class BankAccount

Constructor Summary

Constructor and Description

BankAccount()

Creates a new bank account, asking the user to enter the account name and initial balance.

Method Summary

Modifier and Type	Method and Description
void	deposit(double amount) Deposits the specified amount of money into this account.
double	getBalance() Gets the balance of this account.
void	showBalance() Shows the balance of this account.
void	transfer(double amount, BankAccount targetAccount) Transfers the specified amount of money from this account into the target account.
void	withdraw(double amount) Withdraws the specified amount of money into this account.

Write a program that executes the following steps:

Create a new bank account.

Show the balance of the bank account.

If the balance of the bank account is >= 20 dollars, do the following steps:

Print "Purchasing movie ticket." including the full stop at the end of the sentence.

Withdraw $20 from the account.

Show the balance of the bank account again.

Otherwise, print "You need more money to buy a movie ticket." including the full stop at the end of the sentence.

The following sample I/O shows how your program should behave when the account has at least $20:

Creating a new bank account Enter account name:  user inputs Shelly Martin  Enter initial balance: $  user inputs 567.00  Shelly Martin's account has $567.00 Purchasing movie ticket. Shelly Martin's account has $547.00 

Otherwise, your program should behave as follows:

Creating a new bank account Enter account name:  user inputs Shelly Martin  Enter initial balance: $  user inputs 7.00  Shelly Martin's account has $7.00 You need more money to buy a movie ticket. 

Hint: Apply a pair of "{" and "}" braces around the entire 3 steps of the if case, and then a separate pair of braces around the 1 step of the else case.

import java.util.Scanner;

public class Exercise6 { public static void main(String[] args) { // INSERT YOUR CODE HERE

Scanner scanner = new Scanner(System.in); BankAccount account = new BankAccount(); System.out.print("Enter account name: "); String name = scanner.nextLine(); System.out.print("enter initial balance: $ "); double bal = scanner.nextDouble(); account.deposit(bal); System.out.println(name + "\'s account has $" + account.getBalance()); account.withdraw(20); if (account.getBalance() >= 20) { System.out.println("Purchasing movie ticket."); System.out.println(name + "\'s account has $" + account.getBalance()); } else { System.out.println("You need more money to buy a movie ticket."); }

} }

Output:

Question: It asks the question twice because the BankAccount account = new BankAccount(); line of code asks the question already. How can I adjust my code as it seems to add the two sets of prompts together.
