Question

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).

Then create a 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.
• If a number other than 1, 2, 3, or 4 is received, output "Invalid menu choice." and then stop.

/* Please change the class name to same as the file name of .java file and then compile and run it.

I am also attaching the output for the same. You can run it here also https://www.onlinegdb.com/online_java_compiler but of you are running here make sure to change classname to Main. All the functions and outputs are according to the specifications provided in the question. Thank You*/
