Using Java, How can I change the following code to be a GUI.

import java.text.NumberFormat; // Helps with formatting doubles as currency import java.util.Scanner; // Will be used to get input from the user

public class SavingsAccount { public static void main(String[] args) { // Create and instantiate two Account objects

Account checking = new Account(); checking.setType("Checking"); checking.setBalance(4000.00); checking.setRate(4000.00);

Account savings = new Account(); savings.setType("Savings"); savings.setBalance(4000.00); savings.setRate(4000.00);

NumberFormat formatter = NumberFormat.getCurrencyInstance(); // Creates the formatter object for currency Scanner sc = new Scanner(System.in); // Creates the sc object to read user input

boolean session = true; // This variable will break the (while) loop when false

while (session) {

// Present the user with a menu of 5 options

System.out.print("======================== " +"ATM Menu: " + "1. Deposit Money " + "2. Withdraw Money " + "3. Transfer Funds " + "4. Check Account Balance " + "5. End Session " + "======================== " + " Enter selection: ");

int selection = sc.nextInt(); // assign the user's input to the selection variable

// This switch block will handle one of five selections and deal with them appropriately

switch (selection) {

// case 1 handles the depositing of money

case 1: System.out.print("Enter (1) for Savings or (2) for Checking: "); int depAccount = sc.nextInt(); // Keeps track of which account to deposit money to

if (depAccount == 1) {

System.out.println(" Your current Savings balance is: " + formatter.format(savings.getBalance()) + " ");

System.out.println("How much money would you like to deposit?"); double deposit = sc.nextDouble();

savings.deposit(deposit);

System.out.println(" Your Savings balance is now: " + formatter.format(savings.getBalance()) + " ");

}

else if (depAccount == 2) { System.out.println(" Your current Checking balance is: " + formatter.format(checking.getBalance()) + " ");

System.out.println("How much money would you like to deposit?"); double deposit = sc.nextDouble();

checking.deposit(deposit);

System.out.println(" Checking balance is now: " + formatter.format(checking.getBalance()) + " ");

}

break;

// case 2 handles the withdrawal of money

case 2: System.out.print(" Enter (1) for Savings or (2) for Checking: "); int witAccount = sc.nextInt(); // Keeps track of which account to withdraw from

if (witAccount == 1) {

System.out.println(" Your current Savings balance is: " + formatter.format(savings.getBalance()) + " ");

System.out.println("How much money would you like to withdraw?"); double withdraw = sc.nextDouble();

savings.withdraw(withdraw);

System.out.println(" Your Savings balance is now: " + formatter.format(savings.getBalance()) + " ");

}

else if (witAccount == 2) { System.out.println(" Your current Checking balance is: " + formatter.format(checking.getBalance()) + " ");

System.out.println("How much money would you like to withdraw?"); double withdraw = sc.nextDouble();

checking.withdraw(withdraw);

System.out.println(" Your Checking balance is now: " + formatter.format(checking.getBalance()) + " ");

}

break;

// case 3 handles the transfer of funds

case 3: System.out.print(" From which account do you wish to transfer funds from?, (1) for Savings or (2) for Checking: "); int tranAccount = sc.nextInt();

if (tranAccount == 1) {

System.out.println(" Your current Savings balance is: " + formatter.format(savings.getBalance()) + " ");

System.out.print("How much money do you wish to transfer from Savings to Checking?: "); double tranAmount = sc.nextDouble();

savings.withdraw(tranAmount); checking.deposit(tranAmount);

System.out.println(" You successfully transferred " + formatter.format(tranAmount) + " from Savings to Checking");

System.out.println(" Checking Balance: " + formatter.format(checking.getBalance())); System.out.println("Savings Balance: " + formatter.format(savings.getBalance()) + " ");

}

else if (tranAccount == 2) {

System.out.println(" Your current Checking balance is: " + formatter.format(checking.getBalance()) + " ");

System.out.println(" Checking Balance: " + formatter.format(checking.getBalance())); System.out.println("Savings Balance: " + formatter.format(savings.getBalance()) + " "); }

break; // case 4 simply outputs the balances of both Checking and Savings accounts case 4: System.out.println(" Checking Balance: " + formatter.format(checking.getBalance())); System.out.println("Savings Balance: " + formatter.format(savings.getBalance()) + " "); break;

// case 5 breaks out of the (while) loop when the user is finished using the ATM

case 5: session = false; break;

}

}

System.out.println(" Thank you for banking with us! ");

}

}

class Account {

// Here we declare some variables that a typical bank account will have
