Launch NetBeans, new Java application called “AtmSimulator” (without the quotation marks) (not ATMSimluator!) that simulates a simple one-transaction ATM according to the following guidelines.

The program should start with an initial account balance, which you can set to any legitimate double value. All output of currency values should include a leading dollar sign and use two decimal positions. Prompt the user with the following prompt (without the dashed lines).

Enter the number of your desired transaction type.

1. Balance
2. Deposit
3. Withdrawal
4. Quit

• If a balance is requested, the program should output “Your current balance is $X.XX” where X.XX is the initial balance, and then stop.
• If a deposit is requested, prompt the user to enter the amount of the deposit (use a double for this). Add the deposit amount to the initial balance and then print “Your current balance is $X.XX” where X.XX is the new balance after the deposit, and then stop.
• If a withdrawal is requested, prompt the user to enter the amount of the withdrawal (use a double for this). If the proposed withdrawal amount is less than or equal to the initial balance, print “Your current balance is $X.XX” where X.XX is the new balance after the withdrawal, and then stop. If the proposed withdrawal amount exceeds the initial balance, print “Insufficient funds. Your current balance is $X.XX” where X.XX is the initial balance, and then stop.
• If “Quit” is requested, the program should print “Good-bye.” and then stop.

Thoughts

• Before coding, sketch out the logic that will handle each condition appropriately. 
• Note that this ATM simulator handles, for simplicity, just a single transaction of Balance, Deposit, or Withdrawal.
• Refer to Horstmann chapter 2 for details on formatting output values.
