Your first task is to ensure that the following classes from Assignment 4 are fully functional . BankAccount SavingsAccount . Customer Please use the provided test cases below to test the functionality of these classes before proceeding - note that there are additional test cases against which your code must run Next, create a setter method getCustomer) for the BankAccount class Now, create a new class BankApplication, which is a subclass of javafx.application.Application It should contain the following Instance Variables Customer (give the customer a name and an account ID) SavingsAccount (starting balance of $150.00, and the customer you have created as an instance variable) . The following GUI controls: o Labels: customerNameLabel, customerlDLabel, balanceLabel o Text fields: depositTextField, withdrawTextField Button: executeButton They should be laid out as follows Bank application ustomer name: Charles Brown count ID: 123456 Amt to deposit Execute urrent balance: $150.00. Amt to withdraw Each label and button should be on its own line, but the text fields should be next to each other Hints: Recall that you can add one Group (such as a Hbox) to another Group (such as a VBox) TextFields can be initialized by calling the setPromptText) method)
